CKWaveCollectionViewTransition

This is a cool custom transition between two or more UICollectionViewControllers with wave like cell animation. Could be used in e.g. galleries.

Animation idea was taken from Łukasz Frankiewicz Dribble project

Installation

There are two options:

Via CocoaPods.
Manually add the files into your Xcode project. Slightly simpler, but updates are also manual.

Usage

In storyboard add object in your NavigationController.

Set it's class to NavigationControllerDelegate

Set NavigationController delegate to this object.

Implement UINavigationControllerDelegate in your ViewController:

func navigationController(navigationController: UINavigationController, animationControllerForOperation operation: UINavigationControllerOperation,
        fromViewController fromVC: UIViewController, toViewController toVC: UIViewController) -> UIViewControllerAnimatedTransitioning? {
            
            let animator = CKWaveCollectionViewAnimator()
            
            if operation != UINavigationControllerOperation.Push {
                
                animator.reversed = true
            }
            
            return animator
    }

Properties
