UICollectionView setLayout:animated: not preserving zIndex

Question

I\'ve noticed that when calling setLayout:animated in a UICollectionView to switch between two layouts, the currently visible cell doesn\'t adhere to t

Answer 1

I have had the same problem. Switching the layout will disregard the zIndex for the cell.

I have managed to make it "look right" by applying a translation on the z-axis like this:

attributes.transform3D = CATransform3DMakeTranslation(0, 0, indexPath.row);

But it is just a visual fix, if you try to click on the item you will realize that the zIndex is still wrong until it is recycled by scrolling it offscreen.
