Followed tutorial and all I got was a black screen in the simulator

I'm not sure what I am doing wrong, or how to fix it. I have tried twice now following along the "Ribbit" tutorial, and all I get is a black screen in the simulator when I hit run. When I started with the empty application it ran fine, but once I deleted the code in didFinishLaunchingWithOptions in the AppDelegate all I got was a black screen. The tabbed interface still didn't appear after creating a ViewController for the Inbox. Should they all have ViewControllers before any of them will appear?

Thank You.

I tried targeting iOS 6.1 as well as restarting my computer as well as following the same steps on a different computer with the same version of Xcode. All with the same result, a black screen, no tabbed interface or login screen.

Make sure that you set the default storyboard that the project is using. Under General-> Deployment Info-> Main Interface in the project settings.

In your didFinishLaunchingWithOptions Remove the below code if using Storyboards. or add it back if not using Storyboards to set the rootViewController

    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    [self.window makeKeyAndVisible];
    self.window.rootViewController = yourViewController;

The Main Interface setting did it. So simple, I don't know how I missed that step. Thank you very much. =]

Thank you! I was having the same issue and was getting really frustrated (thought it might have been an Xcode 4 thing when I was using Xcode 5)
