title: UICollectionView: minimumInteritemSpacing change on cell selection
body: <p>In my collection view I want to scale the collection view cell that is selected. Along with that I also want to maintain same interItemSpacing between cells before the selection and after the selection, including enlarged cell. But if I just scale the cell by setting cell.transform property scaled cell overlaps on the neighbor cell.Other cells should adjust themselves to maintain the space. How do I solve this ?</p>
  
  <p>i.e,</p>
  
  <pre><code>  cell -50pix- cell -50pix- cell
  
    cell -50pix- scaled cell -50pix- cell
  </code></pre>
