title: UITableViewController Refresh control is nil
body: <p>I have a UITableViewController in my project and set the "Refreshing" to enabled in Storyboard. However, the outlet of that is nil.</p>
  
  <p>Using it like this</p>
  
  <pre><code>self.refreshControl
  </code></pre>
  
  <p>Even if I make I custom outlet from the storyboard to the viewcontrolelr it is nil. 
  It works for other table views in my project, just not for this.</p>
  
  <p>Is there anything quick I probably have missed?</p>
