title: XCode5 self.navigationController pushViewController:animated: doesn't open the new viewcontroller
body: <p>I'm not sure why but in Xcode 5 working on a project of IOS6.1 I have a button connected to a IBAction in which I'm trying to navigate to a new view controller.</p>
  
  <p>I've tried two different codes to create the viewController and then push it to the navigation in both cases the view controller is not nil and both cases the viewController doesn't appear.</p>
  
  <p>first try: with story Id - I've set the story id of the view controller to imageCapture and set the class to VSImageCaptureViewController </p>
  
  <pre><code>VSImageCaptureViewController* imageCaptureViewController = (VSImageCaptureViewController*)([self.storyboard instantiateViewControllerWithIdentifier:@"imageCapture"]);
  
  [self presentViewController:imageCaptureViewController animated:NO completion:nil];
  </code></pre>
  
  <p>second try: with the name of the viewcontroller </p>
  
  <pre><code>VSImageCaptureViewController *imageCaptureViewController = [[VSImageCaptureViewController alloc] initWithNibName:@"VSImageCaptureViewController" bundle:nil];
  
  [self.navigationController pushViewController:imageCaptureViewController animated:YES]; 
  </code></pre>
  
  <p>can you see something wrong or do you think I forgot to initialize something</p>
