title: UIView in nib not connecting to IBOutlets
body: <p>I am adding on screen a UIView in this way:</p>
  
  <pre><code>ViewController2 *detailViewController = [[ViewController2 alloc] initWithNibName:@"MJDetailViewController" bundle:nil];
  [self presentPopupViewController:detailViewController animationType:MJPopupViewAnimationFade];
  </code></pre>
  
  <p>since MJDetailViewController is a nib and holds a UIView, I have created a custom class of UIView and selected it as class for the view in the inspector. When the window is loaded, the UIButtons do actions in the class that has been created, but the IBOutlets don't work. Even if I decided to add a UIButton programmably, it doesn't appear on screen. Why is this? </p>
  
  <p>I thought of changing the UIView to a UIViewController, but it won't work because you can't present it with an animation.</p>
