UINavigationController not showing the Root View controller

Question

I have a UIView (menuView in code below) of size 320x218 inside a view. I want to load a navigation controller into this view. Im using the following code to do that:

MenuViewController *menuController = [[MenuViewController alloc] initWithNibName:@"MenuViewController" bundle:nil];

UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:menuController];
navigationController.navigationBarHidden = YES;

[menuView addSubview:navigationController.view];
[menuController release];
[navigationController release];

When I execute it, the root view is not displayed in that view. Only a navigation bar is displayed and the rest of the view is empty.

Edit:

I just placed an NSLog() in both initWithNibName: and viewDidLoad: of MenuViewController. The one in initWithNibName: gets called but the one in viewDidLoad: doesn't :S

Update:

I tried to push menuController to my navigationController thinking since its not appearing, it might not be on the stack. Exception:

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Pushing the same view controller instance more than once is not supported

Yes and yes. I just placed an NSLog() in both initWithNibName: and viewDidLoad: of MenuViewController. The one in initWithNibName: gets called but the one in viewDidLoad: doesn't :S — Bushra Shahid, Aug 02 '11 at 09:37
Ok after reading your comment, can you place a line menuController.view; after you create the navigationController? Just add that line and let me know the result. — Praveen S, Aug 02 '11 at 09:38
Just add that line as part of code, you will get a warning but thats ok. — Praveen S, Aug 02 '11 at 09:40
Nothing happened. Got the warning like you said but no exceptions or errors when executed — Bushra Shahid, Aug 02 '11 at 09:42
Were you able to solve this? If not we can continue over chat to discuss in detail. — Praveen S, Aug 02 '11 at 11:42

call layoutsubviews do work.

[super loadView];
[self.view addSubview:navigationController.view];
[navigationController.view layoutSubviews];

I found the answer here:

UIViewController -viewDidLoad not being called

I had to add these lines of code after -initWithRootViewController in order to load the view of my root view Controller:

navigationController.navigationBarHidden = YES;
[navigationController setView:menuController.view];

self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
// Override point for customization after application launch.

ViewController *viewController = [[[ViewController alloc] initWithNibName:@"ViewController" bundle:nil] autorelease];

navController = [[UINavigationController alloc]initWithRootViewController:viewController];

self.window.rootViewController = self.navController;

Try this code in your appdelegate method

You should not add the navigationViewController as an subview To your MenuViewController. As the navigationViewController already already holds the MenuViewController.

Just display the navigationViewController.
