title: UICollectionView is scrolling when selecting a cell
body: <p>I'm having trouble when i try to select an item inside a <code>UICollectionView</code> since when I click on it it scrolls a little bit.</p>
  <p>I know <code>didSelectItemAtIndexPath</code> is being called but I want to prevent the scrolling when selecting. I only want the collection view to scroll when the user is scrolling through but if the user is just tapping the cell it shouldn't move. Only should be selected.</p>
  <p>I hope you can help me since I don't know how to prevent this problem.</p>
  <p>Any help will be really appreciated.</p>
