title: UIImagePickerController.frame is not full screen
body: <p>I'm initializing an <strong>UIImagePickerController</strong> like this:  </p>
  
  <pre><code>    self.cameraController = [[UIImagePickerController alloc] init];
  
      self.cameraController.sourceType = UIImagePickerControllerSourceTypeCamera; 
      self.cameraController.showsCameraControls = NO;
      self.cameraController.navigationBarHidden = YES;
      self.cameraController.wantsFullScreenLayout = YES;
  </code></pre>
  
  <p>The problem is that when this is shown, instead of the camera controls,
  I get a black bar in its place. </p>
  
  <p>How can I make <strong>UIImagePickerController.frame</strong> take all the screen space?</p>
  
  <p>Thanks!</p>
