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
There are two options:
- Via CocoaPods.
- Manually add the files into your Xcode project. Slightly simpler, but updates are also manual.
- In storyboard add 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 self.selectedIndexPath property in your didSelectItemAtIndexPath method implementation.
override func collectionView(collectionView: UICollectionView, didSelectItemAtIndexPath indexPath: NSIndexPath) {
self.selectedIndexPath = indexPath
...
}internal let animationDuration: Double! = 1.0Total animation duration
internal let kCellAnimSmallDelta: Double! = 0.01Small delay between cell animations
internal let kCellAnimBigDelta: Double! = 0.03Big delay between cell animations
