View Controller not presenting from App Delegate

Question

I am trying to load a viewController if there are no accounts logged in however it gives me this error Warning: Attempt to present <DefaultViewController: 0xb96cac0> on <MainViewController: 0xb95c320> whose view is not in the window hierarchy! Here is the code that I am using right now:

BOOL returnAllOff = [[User data] returnAllOff];

if (returnAllOff) {
    DefaultViewController *viewController =[[DefaultViewController alloc]
    init];
    UIViewController *presentingController = [[[[UIApplication sharedApplication] delegate] window] rootViewController];
    [presentingController presentViewController:viewController animated:YES completion:nil];

}

Where is that code? The error is quite clear about the reason. — Wain, Aug 23 '13 at 06:39
Would i Have to add DefaultViewController in the mainviewcontroller class. FYI i am using storyboards. — Prad, Aug 23 '13 at 06:40

Actually this is the correct way of loading a ViewController from AppDelegate..

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

    DefaultViewController *viewController = [[DefaultViewController alloc] initWithNibName:@"DefaultViewController" bundle:nil];
    self.window.rootViewController = viewController;
    [self.window makeKeyAndVisible];

It now gives this issue instead... `*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Could not load NIB in bundle: 'NSBundle (loaded)' with name 'DefaultViewController''` – Prad Aug 23 '13 at 06:42
you are using Storyboards? – Ahmed Z. Aug 23 '13 at 06:43
I added that line now, however when the view loads its all black even though there are 2 buttons and the page is filled with color. @preetam – Prad Aug 23 '13 at 07:04

Try this one by importing DefaultViewController in appDElegate.

self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
DefaultViewController *viewController = [[DefaultViewController alloc] init];
self.window.rootViewController = viewController;
[self.window makeKeyAndVisible];

which color you are giving to view? – Preetam Jadakar Aug 23 '13 at 07:14
its actually a ui image view – Prad Aug 23 '13 at 07:15
I think you are setting view background color to default color that clears everything on view – Preetam Jadakar Aug 23 '13 at 07:16
try taking a new view controller...first check it navigates or not then correspondingly make your required changes to that new view controller so that you can easily track where you were wrong? – Preetam Jadakar Aug 23 '13 at 07:19
