This is an iPad project implementing a simple one-screen app with a UICollectionView. PintCollectionViewLayout is the custom UICollectionViewLayout for the collection view.
The layout supports one section only and does not support decoration or supplemental views.
Inserts and deletes are animated. See the video: PintLayout.mov
