title: Can't set custom class name
body: <p>I can't seem to be able to set the identity of my view to <code>GraphViewController</code> in Xcode 4.2.</p>
  
  <p>I dragged a regular <code>UIView</code> in storyboard on a <code>UIScrollView</code>.</p>
  
  <p>I create a new file called <code>GraphViewController</code> extending <code>UIViewController</code> (<code>.h</code> and <code>.m</code>) but when I click on my view in storyboard and try to set the custom class name (its identity) to <code>GraphViewController</code>, it doesn't set it. It doesn't even show it in the dropdown list. </p>
  
  <p>Am I missing something here a connection or something?</p>
