title: How to change an UIImageView into a custom cell
body: <p>I have an UIImageView in a custom cell (<code>@IBOutlet var imageSquadra: UIImageView!</code>) and in the TableViewController I initialize this imageView:</p>
  
  <pre><code>let squadra = DataManager.sharedInstance.arrayCori[indexPath.row]
  
          cell.imageSquadra.image = squadra.sfondo1
  </code></pre>
  
  <p>Now I need to change the image touching up inside the cell with an other image, and return to the previous image touching up into an other cell.
  Is it hard to do?</p>
  
  <p>EDIT: or if was easier, would be fine apply a CAFilter like a shadow to the image.</p>
