title: Navigation Bar not visible in simulator but visible in storyboard
body: <p>Additional info >></p>
  
  <p>Just noticed that in my application didFinishLaunchingWithOptions: i've got this</p>
  
  <pre><code>self.window = [[UIWindow alloc] initWithFrame:UIScreen.mainScreen.bounds];
  UIViewController *viewController = [[UIViewController alloc]  init];
  viewController = [storyboard instantiateViewControllerWithIdentifier:@"frontScreen"];
  self.window.rootViewController = viewController;
  [self.window makeKeyAndVisible];
  </code></pre>
  
  <p>Is this part of the problem?</p>

  <p>=================</p>
  
  <p>Hi I'm developing an app in storyboard.
  I'm using the publicly available <code>SWRevealViewController</code> to manage some navigation bar reveal menus.</p>
  
  <p>I've set up a simple <code>UIViewController</code>, lets call it <code>WelcomeViewController</code>. I've dragged a segue from the <code>RevealViewController</code> to my new <code>WelcomeViewController</code> and then I've embed in a <code>Navigation Controller</code>. To the navigation bar I've added a menu reveal button.</p>
  
  <p>All looks good in the storyboard, however when I run in the simulator the navigation bar isn't there.
  I've added </p>
  
  <pre><code>self.navigationController.navigationBarHidden = NO;
  </code></pre>
  
  <p>in the <code>viewWillAppear</code> method - to no avail.</p>
  
  <p>I should mention that I've got an entire branch of viewcontrollers and functionality already coming off the revealviewcontroller with no problems.</p>
  
  <p>Any help. I've search stack overflow but found nothing that matches my specific problems. All advice gratefully received.</p>
