title: UITabBarController not showing title of other tabs
body: <p>I'm trying to make a UITabBarController programmatically. This seem to work, i have 2 tabs, the issue it does not show the second tab title in the RootViewController when it is loaded first time. How come?</p>
  
  <p>This is when RootViewController is loaded:</p>

  <p>When i go back the second tab title is still there:</p>

  <p>My question is why it is not showing when the RootViewController is loaded.</p>
  
  <p>my appDelegate method in didFinishLaunchingWithOptions:</p>
  
  <pre><code>tabBarController = [[UITabBarController alloc] init];
  
  MenuViewController *firstTab = [[MenuViewController alloc] initWithNibName:@"MenuViewController" bundle:nil];
  UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:firstTab];
  
  
  FixtureViewController *secondTab = [[FixtureViewController alloc] initWithNibName:@"FixtureViewController" bundle:nil];
  UINavigationController *navController2 = [[UINavigationController alloc] initWithRootViewController:secondTab];
  
  
  self.tabBarController = [[UITabBarController alloc] init];
  self.tabBarController.viewControllers = @[navController, navController2];
  
  [self.window setRootViewController:tabBarController];
  </code></pre>
