Question

I am trying to load a UIStoryboard from the app delegate .m in this way:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{    
    UIStoryboard *storybord = [UIStoryboard storyboardWithName:@"MainStoryboard_iPhone" bundle:[NSBundle mainBundle]];
    UIViewController *vc =[storybord instantiateInitialViewController];
    [self.window addSubview:vc.view];

    return YES;
}

What is the problem with this code?? any idea?

Answer 1

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

   UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard_iPhone" bundle:[NSBundle mainBundle]];
   UIViewController *vc =[storyboard instantiateInitialViewController];

   // Set root view controller and make windows visible
   self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
   self.window.rootViewController = vc;
   [self.window makeKeyAndVisible];

   return YES;
}

Try this. I think is missing set root view controller and make windows visible.
