UICollectionViewCell not calling updateConstraints automatically when dequeued?

autolayout, ios7, uicollectionview

Solution

Implement this method and return YES. This could probably help.

Problem

I have a UICollectionViewCell subclass. I wrote an `updateConstraints` method as I've done a hundred times before. For some reason that is never called when the cell is dequeued. I had to add a manual call to `[cell setNeedsUpdateConstraints]` after dequeueing it. Any idea what could be going on here?
