ios - Preview UICollectionViewCell -


how add preview of next cell in uicollectionview revealed current cell swiped away? such feels stack of cards. borrowing lot of inspiration chrome's ios app , implementation of tab switcher. appreciated.

the best approach i've found far follows:
disable scrolling on uicollectionview,
setup pan gesture,
as pan gesture starts, take screenshot of current cell , add screenshot on top of uicollectionview,
scroll uicollectionview next cell (or previous depending on direction of gesture),
and move screenshot view gesture.
