title: UICollectionView Cell Overlap
body: <p>I have a horizontal UICollectionView. I want to make the cells overlap each other by a certain amount of 60 pixels so that the second cells overlaps the first by 60 pixels and the third overlaps the second by the same amount and so on.</p>
  
  <p>I tried sub classing UICollectionViewFlowLayout. But I am not able to place the UICollectionviewCell on top of one another. </p>
