UICollectionVIew: Animate cells as the view is scrolled

Question

I would like items in my UICollectionView to animate as the user scrolls through the list.

More specifically, I would like each item to gradually flip around as it "leaves" the visible part of the scroll view.

Any suggestions?

You probably want to use UIKit dynamics. Here is a good example: http://www.objc.io/issue-5/collection-views-and-uidynamics.html

There are some pre-set dynamic behaviours described at Apple's documentation ,

The best choice seems to be the UIDynamicItemBehavior , as it has an allowsRotation property.
