title: Swift : How to set Custom UICollectionViewCell as circle?
body: <p>I've custom <code>UICollectionViewCell</code> that contains <code>UILabel</code> and <code>UIImage</code>.
  I want to set the cell in circular format.</p>
  
  <p><strong>Note:-</strong> <code>sizeForItemAtIndexPath</code> cannot be changed due to AutoLayout.</p>
  
  <p>Below is code that I've used :</p>
  
  <pre><code>func collectionView(collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout,sizeForItemAtIndexPath indexPath:NSIndexPath ) -&gt; CGSize {
  
            return CGSize(width: (self.objKeypadCollectionView.frame.size.width/3)-10, height: (self.objKeypadCollectionView.frame.size.height/4)-10)
      }
  
  func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -&gt; UICollectionViewCell {
  
          let objKeypadCollectionViewCell = collectionView.dequeueReusableCellWithReuseIdentifier("idKeypadCollectionViewCell", forIndexPath: indexPath) as! KeypadCollectionViewCell
  
          if (self.numberArray[indexPath.item])=="asda" {
              objKeypadCollectionViewCell.lblNumber.text = ""
              objKeypadCollectionViewCell.imgPrint.hidden = false
          }
          else if (self.numberArray[indexPath.item])=="Derterel" {
              objKeypadCollectionViewCell.lblNumber.text = self.numberArray[indexPath.item]
              objKeypadCollectionViewCell.imgPrint.hidden = true
          }
          else {
              objKeypadCollectionViewCell.imgPrint.hidden = true
              objKeypadCollectionViewCell.lblNumber.text = self.numberArray[indexPath.item]
              objKeypadCollectionViewCell.layer.borderColor = UIColor.lightGrayColor().CGColor
              objKeypadCollectionViewCell.layer.borderWidth = 1
              objKeypadCollectionViewCell.layer.cornerRadius = objKeypadCollectionViewCell.frame.size.width/2
          }
          return objKeypadCollectionViewCell
      }
  </code></pre>
