title: Objective-C: UITabBarController Black Screen
body: <p>Bellow i have some code that is place in the <code>app delegate.m</code> and is used to create a c between two ViewControllers. The creation of the tab bar works fine but when i select the setting tab there is no view it is just black.</p>
  
  <p>Here is the code:</p>
  
  <pre><code>import "ViewController.h"
  #import "Settings.h"
  
  @implementation AppDelegate
  
      - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
      {
          self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
          // Override point for customization after application launch.
          self.viewController = [[ViewController alloc] initWithNibName:@"ViewController" bundle:nil];
          self.window.rootViewController = self.viewController;
          [self.window makeKeyAndVisible];
  
          UITabBarController *tbc = [[UITabBarController alloc]init];
  
          ViewController *vc1 = [[ViewController alloc]initWithNibName:@"ViewController" bundle:nil];
          Settings *vc2 = [[Settings alloc]init];
  
          [vc1.tabBarItem setTitle:@"Browse"];
          [vc2.tabBarItem setTitle:@"Settings"];
  
          [tbc setViewControllers:[NSArray arrayWithObjects:vc1, vc2, nil]];
          [self.window setRootViewController:tbc];
  
          return YES;
      }
  </code></pre>
