title: Back button from xib to storyboard
body: <p>Currently I develop with a StoryBoard for the iPad. Additionally I add a ViewController.xib file with a view. Now I want to back button from xib to storyboard. My code is below but this is not working.</p>
  
  <pre><code>UIStoryboard *storyBoard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];
  UIViewController *initViewController = [storyBoard instantiateInitialViewController];
  [self.navigationController pushViewController:initViewController animated:YES];
  </code></pre>
