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 an object in your NavigationController.
- Set it's class to NavigationControllerDelegate
- Set NavigationController delegate to this object.
or
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
}
- The last thing you have to set is selectedIndexPath property in your didSelectItemAtIndexPath method implementation.
override func collectionView(collectionView: UICollectionView, didSelectItemAtIndexPath indexPath: NSIndexPath) {
selectedIndexPath = indexPath
}
Properties
internal let animationDuration: Double! = 1.0
Total animation duration.
internal let kCellAnimSmallDelta: Double! = 0.01
internal let kCellAnimBigDelta: Double! = 0.03
Properties you can change to adjust animation.
Requirements
- iOS 7.0+
