xcode - iOS UICollectionView not scrolling when cell is touched -


i've created simple grid based uicollectionview i'm having trouble scrolling. if touch view rather cell within seems scroll correctly if touch 1 of cells , try scroll nothing happens. bit of issue, want grid of cells fill view, , when view filled there touch make scroll! guess easiest way describe i'm trying achieve table view 2 columns of cells rather one.

i can't seem find in documentation talks issue , i've tried various combinations of "user interaction enabled" settings etc.

one final thing, require cells respond single tap touch (basically toggle them on , off) don't want disable them responding touches.
