title: iOS UIBarButtonItem link to ViewController
body: <p>I have a question about the <code>UIBarButtonItem</code> to link to another ViewController in the Storyboard. In this top bar I have 2 icons on the Right do this with a array:</p>
  
  <pre><code>[self.navigationItem setRightBarButtonItems:[NSArray arrayWithObjects:_meetupButton, _searchButton, nil]];
  </code></pre>
  
  <p>Both buttons work in the console, but when I want to navigate with the <code>meetupButton</code> to another ViewController, it doesn't work.</p>
  
  <p>Storyboard name is Main
  ViewController is correctly linked to <code>MeetupStartViewController</code>.</p>
  
  <p>When he runs the following code he crashes. What am I doing wrong?</p>
  
  <pre><code>- (void)toggleMeetup:(UIButton *)button {
      UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle: nil];
      UIViewController * vc = [storyboard instantiateViewControllerWithIdentifier:@"MeetupStartViewController"];
      [self presentViewController:vc animated:YES completion:nil];
  }
  </code></pre>
  
  <p>Error log:</p>
