title: iOS UITableViewCell cell.imageView setting rounded corner
body: <p>Hey all I am trying to set <code>cell.imageView</code>'s <code>cornerRadius</code>, but it doesn't seem to work.</p>
  
  <pre><code>cell.imageView.layer.cornerRadius=9;
  </code></pre>
  
  <p>Will it work or should I add a custom <code>UIImageView</code> in my cell to have rounded corners?</p>
  
  <p>I also tried this</p>
  
  <pre><code>cell.imageView.layer.borderWidth=2;
  cell.imageView.layer.borderColor=[[UIColor blackColor]CGColor];
  </code></pre>
  
  <p>But it also doesn't seem to work. Has anybody faced a similar issue?</p>
