Consider the following code:

(BOOL)application:(UIApplication )application didFinishLaunchingWithOptions:(NSDictionary )launchOptions {

    // Set Background Color/Pattern

    self.window.backgroundColor = [UIColor blackColor];

    self.tabBarController.tabBar.backgroundColor = [UIColor clearColor];

    //self.window.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"testbg.png"]];

    // Set StatusBar Color

    [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleBlackTranslucent];

    // Add the tab bar controller's current view as a subview of the window

    self.window.rootViewController = self.tabBarController;

    [self.window makeKeyAndVisible];

    return YES;

}

How can the error be corrected that gets thrown in the console, "Applications are expected to have a root view controller at the end of application launch"?

self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];

MenuViewController *menuViewController = [[MenuViewController alloc]init]; self.window.rootViewController = menuViewController;
