Requirements

PortalTransition supports iOS 7.0 and later,

Dependencies:

• CoreGraphics.framework
• QuartzCore.framework

Usage

Copy PortalTransition folder to your project

Present a UIViewController

Set a viewControllerTransitionDelegate

#import "CYViewControllerTransitioningDelegate.h"

@interface ViewController ()

@property (nonatomic, strong) CYViewControllerTransitioningDelegate *viewControllerTransitionDelegate;

@end


// Instatiate transitionDelegate
self.viewControllerTransitionDelegate = [CYViewControllerTransitioningDelegate new];

NewViewController *newVC = [NewViewController new];
newVC.modalPresentationStyle = UIModalPresentationCustom;
// Set the presentedViewController to delegate's viewController, it will implemente delegate methods for you
self.viewControllerTransitionDelegate.viewController = newVC;
// Just push your viewController
[self presentViewController:newVC animated:YES completion:nil];

Use custom category methods

#import "UIViewController+PortalTransition.h"

// Just call the custom present method
[self presentPortalTransitionViewController:newVC completion:nil];

Push a UIViewController to your UINavigationController's viewcontroller stack

Set a viewControllerTransitionDelegate

#import "CYNavigationControllerDelegate.h"

@interface ViewController ()

@property (nonatomic, strong) CYNavigationControllerDelegate *navDelegate;

@end


// Instatiate transitionDelegate
self.navDelegate = [CYNavigationControllerDelegate new];

NewViewController *newVC = [NewViewController new];
// Set your navigation controller to your navDelegate
self.navDelegate.navController = self.navigationController;
[self presentViewController:newVC animated:YES completion:nil];

Use custom category method

#import "UINavigationController+PortalTransition.h""

// Just call the custom present method
[self.navigationController pushPortalTransitionViewController:vc completion:nil];

Custom animator parameters configuration

*  Gap between the target view and reflection, default is 8.0
*/
@property (nonatomic, assign) CGFloat reflectionGap;


/**
*  ReflectionHeight / targetViewHeight, default is 0.5
*/
@property (nonatomic, assign) CGFloat reflectionScale;

/**
*  Opacity of reflectionView, default is 0.5
*/
@property (nonatomic, assign) CGFloat reflectionAlpha;

/**
*  Target view size / origin view size, default is 0.5
*/
@property (nonatomic, assign) CGFloat targetViewScale;

/**
*  Portal animation duration, default is 2.0
*/
@property (nonatomic, assign) CGFloat portalAnimationDuration;

/**
*  Animation duration, default is 3.O
*/
@property (nonatomic, assign) CGFloat scaleAnimationDuration;

/**
*  Target view scale animation delay after portal animation, default is 0.5
*/
@property (nonatomic, assign) CGFloat delay;

/**
*  UIViewController Transition Style, support UINavigationViewController Push, UIViewController present
*/
@property (nonatomic, assign) CYPortalTransitionStyle portalTransitionStyle;

TODO

• Implemente interactive transition for pop & dismiss view controller
• Cocoapods
• Unit Test
