title: supportedInterfaceOrientations not working
body: <p>I have Tab Bar Controller app with three UIViewController, all done in storyboard.<br>
  Device orientation is set to all, except Upside Down.</p>
  
  <p>For one UIViewController, I have following code:</p>
  
  <pre><code>- (BOOL) shouldAutorotate {
       return NO;
  }
  
  -(NSUInteger)supportedInterfaceOrientations
  {
      return UIInterfaceOrientationPortrait;
  }
  </code></pre>
  
  <p>But still  I can rotate.<br>
  Should not supportedInterfaceOrientations limit that ?</p>
