It is in early development, but Alamofire does support its use on supported platforms. + +Once you have your Swift package set up, adding Alamofire as a dependency is as easy as adding it to the `dependencies` value of your `Package.swift`. + +#### Swift 3 + +```swift +dependencies: [ + .Package(url: "https://github.com/Alamofire/Alamofire.git", majorVersion: 4) +] +``` + +#### Swift 4 + +```swift +dependencies: [ + .package(url: "https://github.com/Alamofire/Alamofire.git", from: "4.0.0") +] +``` + +### Manually + +If you prefer not to use any of the aforementioned dependency managers, you can integrate Alamofire into your project manually. + +#### Embedded Framework + +- Open up Terminal, `cd` into your top-level project directory, and run the following command "if" your project is not initialized as a git repository: + + ```bash + $ git init + ``` + +- Add Alamofire as a git [submodule](http://git-scm.com/docs/git-submodule) by running the following command: + + ```bash + $ git submodule add https://github.com/Alamofire/Alamofire.git + ``` + +- Open the new `Alamofire` folder, and drag the `Alamofire.xcodeproj` into the Project Navigator of your application's Xcode project. + + > It should appear nested underneath your application's blue project icon. Whether it is above or below all the other Xcode groups does not matter. + +- Select the `Alamofire.xcodeproj` in the Project Navigator and verify the deployment target matches that of your application target. +- Next, select your application project in the Project Navigator (blue project icon) to navigate to the target configuration window and select the application target under the "Targets" heading in the sidebar. +- In the tab bar at the top of that window, open the "General" panel. +- Click on the `+` button under the "Embedded Binaries" section. +- You will see two different `Alamofire.xcodeproj` folders each with two different versions of the `Alamofire.framework` nested inside a `Products` folder. + + > It does not matter which `Products` folder you choose from, but it does matter whether you choose the top or bottom `Alamofire.framework`. + +- Select the top `Alamofire.framework` for iOS and the bottom one for OS X. + + > You can verify which one you selected by inspecting the build log for your project.

Dynamic data such as an `Authorization` header whose value can changed based on an authentication system belongs in a `RequestAdapter`. + +The reason the dynamic data MUST be placed into the `RequestAdapter` is to support retry operations. When a `Request` is retried, the original request is not rebuilt meaning the `Router` will not be called again. The `RequestAdapter` is called again allowing the dynamic data to be updated on the original request before retrying the `Request`. + +## Credits + +Alamofire is owned and maintained by the [Alamofire Software Foundation](http://alamofire.org). You can follow them on Twitter at [@AlamofireSF](https://twitter.com/AlamofireSF) for project updates and releases. + +### Security Disclosure + +If you believe you have identified a security vulnerability with Alamofire, you should report it as soon as possible via email to security@alamofire.org. Please do not post it to a public issue tracker. + +## Donations + +The [ASF](https://github.com/Alamofire/Foundation#members) is looking to raise money to officially register as a federal non-profit organization. Registering will allow us members to gain some legal protections and also allow us to put donations to use, tax free. Donating to the ASF will enable us to: + +- Pay our legal fees to register as a federal non-profit organization +- Pay our yearly legal fees to keep the non-profit in good status +- Pay for our mail servers to help us stay on top of all questions and security issues +- Potentially fund test servers to make it easier for us to test the edge cases +- Potentially fund developers to work on one of our projects full-time + +The community adoption of the ASF libraries has been amazing. We are greatly humbled by your enthusiasm around the projects, and want to continue to do everything we can to move the needle forward. With your continued support, the ASF will be able to improve its reach and also provide better legal safety for the core members. If you use any of our libraries for work, see if your employers would be interested in donating. Our initial goal is to raise $1000 to get all our legal ducks in a row and kickstart this campaign.

Data(contentsOf: url) +let image = UIImage(data: data, scale: UIScreen.main.scale)! + +image.af_inflate() +``` + +> Inflating compressed image formats (such as PNG or JPEG) in a background queue can significantly improve drawing performance on the main thread. + +#### Scaling + +```swift +let image = UIImage(named: "unicorn")! +let size = CGSize(width: 100.0, height: 100.0) + +// Scale image to size disregarding aspect ratio +let scaledImage = image.af_imageScaled(to: size) + +// Scale image to fit within specified size while maintaining aspect ratio +let aspectScaledToFitImage = image.af_imageAspectScaled(toFit: size) + +// Scale image to fill specified size while maintaining aspect ratio +let aspectScaledToFillImage = image.af_imageAspectScaled(toFill: size) +``` + +#### Rounded Corners + +```swift +let image = UIImage(named: "unicorn")! +let radius: CGFloat = 20.0 + +let roundedImage = image.af_imageRounded(withCornerRadius: radius) +let circularImage = image.af_imageRoundedIntoCircle() +``` + +#### Core Image Filters + +```swift +let image = UIImage(named: "unicorn")! + +let sepiaImage = image.af_imageFiltered(withCoreImageFilter: "CISepiaTone") + +let blurredImage = image.af_imageFiltered( + withCoreImageFilter: "CIGuassianBlur", + parameters: ["inputRadius": 25] +) +``` + +### Image Filters + +The `ImageFilter` protocol was designed to make it easy to apply a filter operation and cache the result after an image finished downloading. It defines two properties to facilitate this functionality. + +```swift +public protocol ImageFilter { + var filter: Image -> Image { get } + var identifier: String { get } +} +``` + +The `filter` closure contains the operation used to create a modified version of the specified image. The `identifier` property is a string used to uniquely identify the filter operation. This is useful when adding filtered versions of an image to a cache. All identifier properties inside AlamofireImage are implemented using protocol extensions. + +#### Single Pass + +The single pass image filters only perform a single operation on the specified image. + +```swift +let image = UIImage(named: "unicorn")! +let imageFilter = RoundedCornersFilter(radius: 10.0) + +let roundedImage = imageFilter.filter(image) +``` + +The current list of single pass image filters includes: + +- `ScaledToSizeFilter` - Scales an image to a specified size. +- `AspectScaledToFitSizeFilter` - Scales an image from the center while maintaining the aspect ratio to fit within a specified size. +- `AspectScaledToFillSizeFilter` - Scales an image from the center while maintaining the aspect ratio to fill a specified size. Any pixels that fall outside the specified size are clipped. +- `RoundedCornersFilter` - Rounds the corners of an image to the specified radius. +- `CircleFilter` - Rounds the corners of an image into a circle. +- `BlurFilter` - Blurs an image using a `CIGaussianBlur` filter with the specified blur radius. + +> Each image filter is built ontop of the `UIImage` extensions. + +#### Multi-Pass + +The multi-pass image filters perform multiple operations on the specified image. + +```swift +let image = UIImage(named: "avatar")! +let size = CGSize(width: 100.0, height: 100.0) +let imageFilter = AspectScaledToFillSizeCircleFilter(size: size) + +let avatarImage = imageFilter.filter(image) +``` + +The current list of multi-pass image filters includes: + +- `ScaledToSizeWithRoundedCornersFilter` - Scales an image to a specified size, then rounds the corners to the specified radius. +- `AspectScaledToFillSizeWithRoundedCornersFilter` - Scales an image from the center while maintaining the aspect ratio to fit within a specified size, then rounds the corners to the specified radius. +- `ScaledToSizeCircleFilter` - Scales an image to a specified size, then rounds the corners into a circle. +- `AspectScaledToFillSizeCircleFilter` - Scales an image from the center while maintaining the aspect ratio to fit within a specified size, then rounds the corners into a circle. + +### Image Cache + +Image caching can become complicated when it comes to network images. `URLCache` is quite powerful and does a great job reasoning through the various cache policies and `Cache-Control` headers. However, it is not equipped to handle caching multiple modified versions of those images. + +For example, let's say you need to download an album of images. Your app needs to display both the thumbnail version as well as the full size version at various times. Due to performance issues, you want to scale down the thumbnails to a reasonable size before rendering them on-screen. You also need to apply a global CoreImage filter to the full size images when displayed. While `URLCache` can easily handle storing the original downloaded image, it cannot store these different variants. What you really need is another caching layer designed to handle these different variants. + +```swift +let imageCache = AutoPurgingImageCache( + memoryCapacity: 100_000_000, + preferredMemoryUsageAfterPurge: 60_000_000 +) +``` + +The `AutoPurgingImageCache` in AlamofireImage fills the role of that additional caching layer. It is an in-memory image cache used to store images up to a given memory capacity. When the memory capacity is reached, the image cache is sorted by last access date, then the oldest image is continuously purged until the preferred memory usage after purge is met. Each time an image is accessed through the cache, the internal access date of the image is updated. + +#### Add / Remove / Fetch Images + +Interacting with the `ImageCache` protocol APIs is very straightforward. + +```swift +let imageCache = AutoPurgingImageCache() +let avatarImage = UIImage(data: data)! + +// Add +imageCache.add(avatarImage, withIdentifier: "avatar") + +// Fetch +let cachedAvatar = imageCache.image(withIdentifier: "avatar") + +// Remove +imageCache.removeImage(withIdentifier: "avatar") +``` + +#### URL Requests + +The `ImageRequestCache` protocol extends the `ImageCache` protocol by adding support for `URLRequest` caching. This allows a `URLRequest` and an additional identifier to generate the unique identifier for the image in the cache. + +```swift +let imageCache = AutoPurgingImageCache() + +let urlRequest = URLRequest(url: URL(string: "https://httpbin.org/image/png")!) +let avatarImage = UIImage(named: "avatar")!.af_imageRoundedIntoCircle() + +// Add +imageCache.add(avatarImage, for: urlRequest, withIdentifier: "circle") + +// Fetch +let cachedAvatarImage = imageCache.image(for: urlRequest, withIdentifier: "circle") + +// Remove +imageCache.removeImage(for: urlRequest, withIdentifier: "circle") +``` + +#### Auto-Purging + +Each time an image is fetched from the cache, the cache internally updates the last access date for that image. + +```swift +let avatar = imageCache.image(withIdentifier: "avatar") +let circularAvatar = imageCache.image(for: urlRequest, withIdentifier: "circle") +``` + +By updating the last access date for each image, the image cache can make more informed decisions about which images to purge when the memory capacity is reached. The `AutoPurgingImageCache` automatically evicts images from the cache in order from oldest last access date to newest until the memory capacity drops below the `preferredMemoryCapacityAfterPurge`. + +> It is important to set reasonable default values for the `memoryCapacity` and `preferredMemoryCapacityAfterPurge` when you are initializing your image cache. By default, the `memoryCapacity` equals 100 MB and the `preferredMemoryCapacityAfterPurge` equals 60 MB. + +#### Memory Warnings + +The `AutoPurgingImageCache` also listens for memory warnings from your application and will purge all images from the cache if a memory warning is observed. + +### Image Downloader + +The `ImageDownloader` class is responsible for downloading images in parallel on a prioritized queue. It uses an internal Alamofire `SessionManager` instance to handle all the downloading and response image serialization. By default, the initialization of an `ImageDownloader` uses a default `URLSessionConfiguration` with the most common parameter values. + +```swift +let imageDownloader = ImageDownloader( + configuration: ImageDownloader.defaultURLSessionConfiguration(), + downloadPrioritization: .fifo, + maximumActiveDownloads: 4, + imageCache: AutoPurgingImageCache() +) +``` + +> If you need to customize the `URLSessionConfiguration` type or parameters, then simply provide your own rather than using the default. + +#### Downloading an Image + +```swift +let downloader = ImageDownloader() +let urlRequest = URLRequest(url: URL(string: "https://httpbin.org/image/jpeg")!) + +downloader.download(urlRequest) { response in + print(response.request) + print(response.response) + debugPrint(response.result) + + if let image = response.result.value { + print(image) + } +} +``` + +> Make sure to keep a strong reference to the `ImageDownloader` instance, otherwise the `completion` closure will not be called because the `downloader` reference will go out of scope before the `completion` closure can be called. + +#### Applying an ImageFilter + +```swift +let downloader = ImageDownloader() +let urlRequest = URLRequest(url: URL(string: "https://httpbin.org/image/jpeg")!) +let filter = AspectScaledToFillSizeCircleFilter(size: CGSize(width: 100.0, height: 100.0)) + +downloader.download(urlRequest, filter: filter) { response in + print(response.request) + print(response.response) + debugPrint(response.result) + + if let image = response.result.value { + print(image) + } +} +``` + +#### Authentication + +If your images are behind HTTP Basic Auth, you can append the `user:password:` or the `credential` to the `ImageDownloader` instance. The credentials will be applied to all future download requests. + +```swift +let downloader = ImageDownloader() +downloader.addAuthentication(user: "username", password: "password") +``` + +#### Download Prioritization + +The `ImageDownloader` maintains an internal queue of pending download requests. Depending on your situation, you may want incoming downloads to be inserted at the front or the back of the queue. The `DownloadPrioritization` enumeration allows you to specify which behavior you would prefer. + +```swift +public enum DownloadPrioritization { + case fifo, lifo +} +``` + +> The `ImageDownloader` is initialized with a `.fifo` queue by default. + +#### Image Caching + +The `ImageDownloader` uses a combination of an `URLCache` and `AutoPurgingImageCache` to create a very robust, high performance image caching system. + +##### URLCache + +The `URLCache` is used to cache all the original image content downloaded from the server. By default, it is initialized with a memory capacity of 20 MB and a disk capacity of 150 MB. This allows up to 150 MB of original image data to be stored on disk at any given time. While these defaults have been carefully set, it is very important to consider your application's needs and performance requirements and whether these values are right for you. + +> If you wish to disable this caching layer, create a custom `URLSessionConfiguration` with the `urlCache` property set to `nil` and use that configuration when initializing the `ImageDownloader`. + +##### Image Cache + +The `ImageCache` is used to cache all the potentially filtered image content after it has been downloaded from the server. This allows multiple variants of the same image to also be cached, rather than having to re-apply the image filters to the original image each time it is required. By default, an `AutoPurgingImageCache` is initialized with a memory capacity of 100 MB and a preferred memory usage after purge limit of 60 MB. This allows up to 100 MB of most recently accessed filtered image content to be stored in-memory at a given time. + +##### Setting Ideal Capacity Limits + +Determining the ideal the in-memory and on-disk capacity limits of the `URLCache` and `AutoPurgingImageCache` requires a bit of forethought. You must carefully consider your application's needs, and tailor the limits accordingly. By default, the combination of caches offers the following storage capacities: + +- 150 MB of on-disk storage +- 20 MB of in-memory original image data storage +- 100 MB of in-memory storage of filtered image content +- 60 MB preferred memory capacity after purge of filtered image content + +> If you do not use image filters, it is advised to set the memory capacity of the `URLCache` to zero to avoid storing the same content in-memory twice. + +#### Duplicate Downloads + +Sometimes application logic can end up attempting to download an image more than once before the initial download request is complete. Most often, this results in the image being downloaded more than once. AlamofireImage handles this case elegantly by merging the duplicate downloads. The image will only be downloaded once, yet both completion handlers will be called. + +##### Image Filter Reuse + +In addition to merging duplicate downloads, AlamofireImage can also merge duplicate image filters. If two image filters with the same identifier are attached to the same download, the image filter is only executed once and both completion handlers are called with the same resulting image. This can save large amounts of time and resources for computationally expensive filters such as ones leveraging CoreImage. + +##### Request Receipts + +Sometimes it is necessary to cancel an image download for various reasons. AlamofireImage can intelligently handle cancellation logic in the `ImageDownloader` by leveraging the `RequestReceipt` type along with the `cancelRequestForRequestReceipt` method. Each download request vends a `RequestReceipt` which can be later used to cancel the request. + +By cancelling the request through the `ImageDownloader` using the `RequestReceipt`, AlamofireImage is able to determine how to best handle the cancellation. The cancelled download will always receive a cancellation error, while duplicate downloads are allowed to complete. If the download is already active, it is allowed to complete even though the completion handler will be called with a cancellation error. This greatly improves performance of table and collection views displaying large amounts of images. + +> It is NOT recommended to directly call `cancel` on the `request` in the `RequestReceipt`. Doing so can lead to issues such as duplicate downloads never being allowed to complete. + +### UIImageView Extension + +The [UIImage Extensions](#uiimage-extensions), [Image Filters](#image-filters), [Image Cache](#image-cache) and [Image Downloader](#image-downloader) were all designed to be flexible and standalone, yet also to provide the foundation of the `UIImageView` extension. Due to the powerful support of these classes, protocols and extensions, the `UIImageView` APIs are concise, easy to use and contain a large amount of functionality. + +#### Setting Image with URL + +Setting the image with a URL will asynchronously download the image and set it once the request is finished. + +```swift +let imageView = UIImageView(frame: frame) +let url = URL(string: "https://httpbin.org/image/png")! + +imageView.af_setImage(withURL: url) +``` + +> If the image is cached locally, the image is set immediately. + +#### Placeholder Images + +By specifying a placeholder image, the image view uses the placeholder image until the remote image is downloaded. + +```swift +let imageView = UIImageView(frame: frame) +let url = URL(string: "https://httpbin.org/image/png")! +let placeholderImage = UIImage(named: "placeholder")! + +imageView.af_setImage(withURL: url, placeholderImage: placeholderImage) +``` + +> If the remote image is cached locally, the placeholder image is never set. + +#### Image Filters + +If an image filter is specified, it is applied asynchronously after the remote image is downloaded. Once the filter execution is complete, the resulting image is set on the image view. + +```swift +let imageView = UIImageView(frame: frame) + +let url = URL(string: "https://httpbin.org/image/png")! +let placeholderImage = UIImage(named: "placeholder")! + +let filter = AspectScaledToFillSizeWithRoundedCornersFilter( + size: imageView.frame.size, + radius: 20.0 +) + +imageView.af_setImage( + withURL: url, + placeholderImage: placeholderImage, + filter: filter +) +``` + +> If the remote image with the applied filter is cached locally, the image is set immediately. + +#### Image Transitions + +By default, there is no image transition animation when setting the image on the image view. If you wish to add a cross dissolve or flip-from-bottom animation, then specify an `ImageTransition` with the preferred duration. + +```swift +let imageView = UIImageView(frame: frame) + +let url = URL(string: "https://httpbin.org/image/png")! +let placeholderImage = UIImage(named: "placeholder")! + +let filter = AspectScaledToFillSizeWithRoundedCornersFilter( + size: imageView.frame.size, + radius: 20.0 +) + +imageView.af_setImage( + withURL: url, + placeholderImage: placeholderImage, + filter: filter, + imageTransition: .crossDissolve(0.2) +) +``` + +> If the remote image is cached locally, the image transition is ignored. + +#### Image Downloader + +The `UIImageView` extension is powered by the default `ImageDownloader` instance. To customize cache capacities, download priorities, request cache policies, timeout durations, etc., please refer to the [Image Downloader](#image-downloader) documentation. + +##### Authentication + +If an image requires and authentication credential from the `UIImageView` extension, it can be provided as follows: + +```swift +ImageDownloader.default.addAuthentication(user: "user", password: "password") +``` + +--- + +## Credits + +Alamofire is owned and maintained by the [Alamofire Software Foundation](http://alamofire.org).

[] // optional + default value +} +``` + +#### `mutating func mapping(map: Map)` + +这个方法是在 Model 转回 JSON 时调用的。因为不可变的属性不能被 `<-` 映射，所以映射回来时需要使用 `>>>` 。 + +```swift +mutating func mapping(map: Map) { + name >>> map["name"] + createdAt >>> (map["createdAt"], DateTransform()) + updatedAt >>> (map["updatedAt"], DateTransform()) + posts >>> map["posts"] +} +``` +# 轻松映射嵌套对象 + +ObjectMapper 支持使用点语法来轻松实现嵌套对象的映射。比如有如下的 JSON 字符串： + +```json +"distance" : { + "text" : "102 ft", + "value" : 31 +} +``` +你可以通过这种写法直接访问到嵌套对象： + +```swift +func mapping(map: Map) { + distance <- map["distance.value"] +} +``` +嵌套的键名也支持访问数组中的值。如果有一个返回的 JSON 是一个包含 distance 的数组，可以通过这种写法访问： + +``` +distance <- map["distances.0.value"] +``` +如果你的键名刚好含有 `.` 符号，你需要特别声明关闭上面提到的获取嵌套对象功能： + +```swift +func mapping(map: Map) { + identifier <- map["app.identifier", nested: false] +} +``` +如果刚好有嵌套的对象的键名还有 `.` ,可以在中间加入一个自定义的分割符（[#629](https://github.com/Hearst-DD/ObjectMapper/pull/629)）: +```swift +func mapping(map: Map) { + appName <- map["com.myapp.info->com.myapp.name", delimiter: "->"] +} +``` +这种情况的 JSON 是这样的： + +```json +"com.myapp.info" : { + "com.myapp.name" : "SwiftOldDriver" +} +``` + +# 自定义转换规则 +ObjectMapper 也支持在映射时自定义转换规则。如果要使用自定义转换，创建一个 tuple（元祖）包含 ```map["field_name"]``` 和你要使用的变换放在 ```<-``` 的右边： + +```swift +birthday <- (map["birthday"], DateTransform()) +``` +当解析 JSON 时上面的转换会把 JSON 里面的 Int 值转成一个 NSDate ，如果是对象转为 JSON 时，则会把 NSDate 对象转成 Int 值。 + +只要实现```TransformType``` 协议就可以轻松的创建自定义的转换规则： + +```swift +public protocol TransformType { + associatedtype Object + associatedtype JSON + + func transformFromJSON(_ value: Any?) -> Object? + func transformToJSON(_ value: Object?) -> JSON? +} +``` + +### TransformOf +大多数情况下你都可以使用框架提供的转换类 ```TransformOf``` 来快速的实现一个期望的转换。 ```TransformOf``` 的初始化需要两个类型和两个闭包。两个类型声明了转换的目标类型和源类型，闭包则实现具体转换逻辑。 + +举个例子，如果你想要把一个 JSON 字符串转成 Int ，你可以像这样使用 ```TransformOf``` ： + +```swift +let transform = TransformOf(fromJSON: { (value: String?) -> Int? in + // 把值从 String? 转成 Int? + return Int(value!) +}, toJSON: { (value: Int?) -> String? in + // 把值从 Int? 转成 String? + if let value = value { + return String(value) + } + return nil +}) + +id <- (map["id"], transform) +``` +这是一种更省略的写法： + +```swift +id <- (map["id"], TransformOf(fromJSON: { Int($0!) }, toJSON: { $0.map { String($0) } })) +``` +# 继承 + +实现了 ```Mappable``` 协议的类可以容易的被继承。当继承一个 mappable 的类时，使用这样的结构： + +```swift +class Base: Mappable { + var base: String? + + required init?(map: Map) { + + } + + func mapping(map: Map) { + base <- map["base"] + } +} + +class Subclass: Base { + var sub: String? + + required init?(map: Map) { + super.init(map) + } + + override func mapping(map: Map) { + super.mapping(map) + + sub <- map["sub"] + } +} +``` + +注意确认子类中的实现调用了父类中正确的初始化器和映射函数。 + +# 泛型对象 + +ObjectMapper 可以处理泛型只要这个泛型也实现了`Mappable`协议。看这个例子： + +```swift +class Result: Mappable { + var result: T? + + required init?(map: Map){ + + } + + func mapping(map: Map) { + result <- map["result"] + } +} + +let result = Mapper>().map(JSON) +``` +# 映射时的上下文对象 + +`Map` 是在映射时传入的对象，带有一个 optional `MapContext` 对象，开发者可以通过使用这个对象在映射时传入一些信息。 + +为了使用这个特性，需要先创建一个对象实现了 `MapContext` 协议（这个协议是空的），然后在初始化时传入 `Mapper` 中。 + +```swift +struct Context: MapContext { + var importantMappingInfo = "映射时需要知道的额外信息" +} + +class User: Mappable { + var name: String? + + required init?(map: Map){ + + } + + func mapping(map: Map){ + if let context = map.context as? Context { + // 获取到额外的信息 + } + } +} + +let context = Context() +let user = Mapper(context: context).map(JSONString) +``` + +# ObjectMapper + Alamofire + +如果网络层你使用的是 [Alamofire](https://github.com/Alamofire/Alamofire) ，并且你希望把返回的结果转换成 Swift 对象，你可以使用 [AlamofireObjectMapper](https://github.com/tristanhimmelman/AlamofireObjectMapper) 。这是一个使用 ObjectMapper 实现的把返回的 JSON 自动转成 Swift 对象的 Alamofire 的扩展。 + + +# ObjectMapper + Realm + +ObjectMapper 可以和 Realm 一起配合使用。使用下面的声明结构就可以使用 ObjectMapper 生成 Realm 对象： + +```swift +class Model: Object, Mappable { + dynamic var name = "" + + required convenience init?(map: Map) { + self.init() + } + + func mapping(map: Map) { + name <- map["name"] + } +} +``` + +如果你想要序列化相关联的 RealmObject，你可以使用 [ObjectMapper+Realm](https://github.com/jakenberg/ObjectMapper-Realm)。这是一个简单的 Realm 扩展，用于把任意的 JSON 序列化成 Realm 的类（ealm's List class。） + +注意：使用 ObjectMappers 的 `toJSON` 函数来生成 JSON 字符串只在 Realm 的写事务中有效（write transaction）。这是因为 ObjectMapper 在解析和生成时在映射函数（ `<-` ）中使用 `inout` 作为标记（ flag ）。Realm 会检测到标记并且强制要求 `toJSON` 函数只能在一个写的事务中调用，即使这个对象并没有被修改。 + +# 待完成 +- 改善错误的处理。可能使用 `throws` 来处理。 +- 相关类的文档完善 + +# 安装 +### Cocoapods +如果你的项目使用 [CocoaPods 0.36 及以上](http://blog.cocoapods.org/Pod-Authors-Guide-to-CocoaPods-Frameworks/) 的版本，你可以把下面内容添加到在 `Podfile` 中，将 ObjectMapper 添加到你的项目中: + +```ruby +pod 'ObjectMapper', '~> 2.2' +``` + +### Carthage +如果你的项目使用 [Carthage](https://github.com/Carthage/Carthage) ，你可以把下面的内容添加到 `Cartfile` 中，将 ObjectMapper 的依赖到你的项目中： + +``` +github "Hearst-DD/ObjectMapper" ~> 2.2 +``` + +### Swift Package Manager +如果你的项目使用 [Swift Package Manager](https://swift.org/package-manager/) ，那么你可以把下面内容添加到 `Package.swift` 中的 `dependencies` 数组中，将 ObjectMapper 的依赖到你的项目中： + +```swift +.Package(url: "https://github.com/Hearst-DD/ObjectMapper.git", majorVersion: 2, minor: 2), +``` + + +### Submodule +此外，ObjectMapper 也可以作为一个 submodule 添加到项目中： + +1. 打开终端，使用 `cd` 命令进入项目文件的根目录下，然后在终端中输入 `git submodule add https://github.com/Hearst-DD/ObjectMapper.git` ，把 ObjectMapper 作为项目的一个 [submodule](http://git-scm.com/docs/git-submodule) 添加进来。 +2. 打开 `ObjectMapper` 文件，并将 `ObjectMapper.xcodeproj` 拖进你 app 项目的文件导航中。 +3. 在 Xcode 中，文件导航中点击蓝色项目图标进入到 target 配置界面，在侧边栏的 "TARGETS" 下选择主工程对应的target。 +4. 确保 `ObjectMapper.framework` 的部署版本( deployment target )和主工程的部署版本保持一致。 +5. 在配置界面的顶部选项栏中，打开 "Build Phases" 面板。 +6. 展开 "Target Dependencies" 组，并添加 `ObjectMapper.framework` 。 +7. 点击面板左上角的 `+` 按钮,选择 "New Copy Files Phase"。将这个阶段重命名为 "Copy Frameworks"，设置 "Destination" 为 "Frameworks"，最后添加 `ObjectMapper.framework` 。 + + diff --git a/TradeRev-coding-challenge/Pods/ObjectMapper/Sources/CustomDateFormatTransform.swift b/TradeRev-coding-challenge/Pods/ObjectMapper/Sources/CustomDateFormatTransform.swift new file mode 100644 index 00000000..3cd5c596 --- /dev/null +++ b/TradeRev-coding-challenge/Pods/ObjectMapper/Sources/CustomDateFormatTransform.swift @@ -0,0 +1,40 @@ +// +// CustomDateFormatTransform.swift +// ObjectMapper +// +// Created by Dan McCracken on 3/8/15. +// +// The MIT License (MIT) +// +// Copyright (c) 2014-2016 Hearst +// +// Permission is hereby granted, free of charge, to any person obtaining a copy +// of this software and associated documentation files (the "Software"), to deal +// in the Software without restriction, including without limitation the rights +// to use, copy, modify, merge, publish, distribute, sublicense, and/or sell +// copies of the Software, and to permit persons to whom the Software is +// furnished to do so, subject to the following conditions: +// +// The above copyright notice and this permission notice shall be included in +// all copies or substantial portions of the Software. +// +// THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR +// IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, +// FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
