I’ve mentioned a number of custom UICollectionView layouts such as SACollectionViewVerticalScalingFlowLayout which automatically scales cells up and down as they get in or out of view.
Here’s an open source UICollectionView layout called StickyCollectionView from Bogdan Matveev.
StickyCollectionView allows you to present cells in an manner in which the cells can overlap and stick to each other, and then when the user scrolls the cells will stop at the top of the view.
This image from the readme shows the included example project in action:
You can find StickyCollectionView on Github here.
