title: Set rounded corners on UIimage in UICollectionViewCell in swift
body: <p>I have a simple problem that I cannot find a solution to on google, the docs or here.</p>
  
  <p>I have a Collectionview in my view controller. I have created a custom cell, DescriptionCell, that contains a UIImage. I want this image to have rounded corners. However, I don't know where to set the cornerradius on the UIImage layer. I have tried in the cells' awakeFromNib method, in the delegate method CellForRowAtIndexPath and overriden LayoutSubview in the cell but it does not work.
  Where should I put the code to set the radius for the UIImage?</p>
  
  <p>To specify, I know how to create rounded corners of a UIImage. But if it is a subview of a Collectionview cell, I do not know where to set the cornerradius.</p>
  
  <p>Here is code for my descriptionCell</p>
  
  <pre><code>class DescriptionCell: UICollectionViewCell {
      @IBOutlet weak var mImage: UIImageView!
  
      override func awakeFromNib() {
      //mImage.layer.cornerradius = 5 
      //Does not work, the image is still square in the cell
      }
  </code></pre>
  
  <p>And in the cellforRowAtIndePath</p>
  
  <pre><code> func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -&gt; UICollectionViewCell {
  var cell = collectionView.dequeueReusableCellWithReuseIdentifier("descriptioncell", forIndexPath: indexPath) as! DescriptionCell
      //cell.mImage.layer.cornerradius = 5 
      //Does not work, the image is still square in the cell
  return cell    
  }
  </code></pre>
  
  <p>Thanks in advance!</p>
