Summary: A collection view cell cannot be **selected** if the collection view delegate indicates that the cell should not be **highlighted**. These should be independent factors, as the collection view delegate also has a method to indicate that a cell should not be highlighted. Steps to Reproduce: 1. Create a collection view 2. Click on a cell; it is selected normally. 3. Implement the UICollectionViewDelegate method collectionView:shouldHighlightItemAtIndexPath: and return NO 4. Click on a cell; it is NOT selected. Expected Results: collectionView:shouldHighlightItemAtIndexPath: should not have any impact on whether the cell is selected. After all, that's what collectionView:shouldSelectItemAtIndexPath: is for. Actual Results: Returning NO from collectionView:shouldHighlightItemAtIndexPath: prevents the cell from being selected. setSelected: on the UICollectionViewCell object is not called. Version: iOS 7.1 (11D167) Notes: Potentially related to rdar://16645887 It's possible that this is the intended behavior, and the documentation needs to be updated.
