Easy QR code scanning on iOS 7.
Add the dependency to your Podfile:
platform :ios
pod 'CDZQRScanningViewController'
...Run pod install to install the dependencies.
#import "CDZQRScanningViewController.h", then:
// assume this text field is defined elsewhere:
UITextField *field = self.someTextField;
[field becomeFirstResponder];
// create the scanning view controller and a navigation controller in which to present it:
CDZQRScanningViewController *scanningVC = [CDZQRScanningViewController new];
UINavigationController *scanningNavVC = [[UINavigationController alloc] initWithRootViewController:scanningVC];
// configure the scanning view controller:
scanningVC.resultBlock = ^(NSString *result) {
field.text = result;
[scanningNavVC dismissViewControllerAnimated:YES completion:nil];
};
scanningVC.cancelBlock = ^() {
[scanningNavVC dismissViewControllerAnimated:YES completion:nil];
};
scanningVC.errorBlock = ^(NSError *error) {
// todo: show a UIAlertView orNSLog the error
[scanningNavVC dismissViewControllerAnimated:YES completion:nil];
};
// present the view controller full-screen on iPhone; in a form sheet on iPad:
scanningNavVC.modalPresentationStyle = UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone ? UIModalPresentationFullScreen : UIModalPresentationFormSheet;
[self presentViewController:scanningNavVC animated:YES completion:nil];If you don't want to present the scanner in its own modal UIViewController, use view controller containment to embed it in your own view controller, instead of presenting it inside a nav controller as in this example.
Tap and hold on the live video view for 0.25 seconds to activate the device's flashlight for use in low-light.
