title: Identify Cell after Tap Location in UICollectionView
body: <p>I have attached a UILongPressGestureRecognizer to a Collection View with the aim of the user hold finger on a cell in the table and being asked if they want to remove it.</p>
  
  <p>The problem I have is that I can not get the indexPath like I would with a table cell (using indexPathForRowAtPoint), is there an equivalent?</p>
  
  <p>If not I have thought about adding the gesture to each cell, but then how do I identify the which gesture (I can not see a "tag" for a gesture), e.g. can I send indexPath.item in the selector? Or some other method?</p>
