RZTransitions: An Objective-C repository from enze0923

RZTransitions is a library to help make iOS7 custom View Controller transitions slick and simple.

Installation

CocoaPods (Recommended)

Add the following to your Podfile:

pod 'RZTransitions'

RZTransitions follows semantic versioning conventions. Check the releases page for the latest updates and version history.

Manual Installation

Copy and add all of the files in the RZTransitions directory (and its subdirectories) into your project.

Setting a New Default Transition

Swift

RZTransitionsManager.shared().defaultPresentDismissAnimationController = RZZoomAlphaAnimationController()
RZTransitionsManager.shared().defaultPushPopAnimationController = RZCardSlideAnimationController()

Objective-C

id<RZAnimationControllerProtocol> presentDismissAnimationController = [[RZZoomAlphaAnimationController alloc] init];
id<RZAnimationControllerProtocol> pushPopAnimationController = [[RZCardSlideAnimationController alloc] init];
[[RZTransitionsManager shared] setDefaultPresentDismissAnimationController:presentDismissAnimationController];
[[RZTransitionsManager shared] setDefaultPushPopAnimationController:pushPopAnimationController];

When Presenting a View Controller

Swift

self.transitioningDelegate = RZTransitionsManager.shared()
let nextViewController = UIViewController()
nextViewController.transitioningDelegate = RZTransitionsManager.shared()
self.presentViewController(nextViewController, animated:true) {}

Objective-C

[self setTransitioningDelegate:[RZTransitionsManager shared]];
UIViewController *nextViewController = [[UIViewController alloc] init];
[nextViewController setTransitioningDelegate:[RZTransitionsManager shared]];
[self presentViewController:nextViewController animated:YES completion:nil];

When creating a Navigation Controller ( or use RZTransitionsNavigationController )

Swift

let navigationController = UINavigationController()
navigationController.delegate = RZTransitionsManager.shared()

Objective-C

UINavigationController *navigationController = [[UINavigationController alloc] init];
[navigationController setDelegate:[RZTransitionsManager shared]];

Specifying Transitions for Specific View Controllers

Swift

RZTransitionsManager.shared().setAnimationController( RZZoomPushAnimationController(),
    fromViewController:self.dynamicType,
    toViewController:RZSimpleCollectionViewController.self,
    forAction:.PushPop)

Objective-C

// Use the RZZoomPushAnimationController when pushing from this view controller to a
// RZSimpleCollectionViewController or popping from a RZSimpleCollectionViewController to
// this view controller.
[[RZTransitionsManager shared] setAnimationController:[[RZZoomPushAnimationController alloc] init]
                                   fromViewController:[self class]
                                     toViewController:[RZSimpleCollectionViewController class]
                                            forAction:RZTransitionAction_PushPop];

Hooking up Interactors

Swift

override func viewDidLoad() {
    super.viewDidLoad()

    self.presentInteractionController = RZVerticalSwipeInteractionController()
    if let vc = self.presentInteractionController as? RZVerticalSwipeInteractionController {
        vc.nextViewControllerDelegate = self
        vc.attachViewController(self, withAction:.Present)
    }
}

override func viewWillAppear(animated: Bool)
{
    super.viewWillAppear(animated)
    RZTransitionsManager.shared().setInteractionController( self.presentInteractionController,
        fromViewController:self.dynamicType,
        toViewController:nil,
        forAction:.Present)
}

Objective-C

@property (nonatomic, strong) id<RZTransitionInteractionController> presentInteractionController;

- (void)viewDidLoad
{
   [super viewDidLoad];
	// Create the presentation interaction controller that allows a custom gesture
	// to control presenting a new VC via a presentViewController
   self.presentInteractionController = [[RZVerticalSwipeInteractionController alloc] init];
   [self.presentInteractionController setNextViewControllerDelegate:self];
   [self.presentInteractionController attachViewController:self withAction:RZTransitionAction_Present];
}

- (void)viewWillAppear:(BOOL)animated
{
   [super viewWillAppear:animated];
	//  Use the present interaction controller for presenting any view controller from this view controller
   [[RZTransitionsManager shared] setInteractionController:self.presentInteractionController
                                        fromViewController:[self class]
                                          toViewController:nil
                                                 forAction:RZTransitionAction_Present];
}

Features

A comprehensive library of animation controllers
A comprehensive library of interaction controllers
Mix and match any animation controller with any interaction controller
A shared instance manager that helps wrap the iOS7 custom transition protocol to expose a friendlier API

You can use any of the animation controllers or interaction controllers without the RZTransitionsManager and simply use them with the iOS7 custom View Controller transition APIs.
