UINavigationController displaying title, but not view

Question

In my app, I've got a mainViewController that I'm trying to use for holding and controlling a couple of main view for my app. I first loaded up a splash screen, but then am wanting to have it so that when a user taps on the splash screen, they are taken to the main menu.

I've got the splash screen part working fine, but I'm having trouble with the NavigationController part.

[splashView.view removeFromSuperview];

mainMenu = [[menuScreenViewController alloc] initWithNibName:@"menuScreenViewController" bundle:nil]; mainMenu.title = @"Menu"; mainNavController = [[UINavigationController alloc] init]; [mainNavController pushViewController:mainMenu animated:NO];

[MAINVC.view addSubview:mainNavController.view];

[mainMenu release]; [mainNavController release];

[splashView release];

(MAINVC is defined elsewhere to be my main view controller).

Anyway, when I do this, I get the navigation controller with the title 'Menu', but the view contained in the mainMenu view controller do not show up in the navigation controller.

If I simply add the mainMenu's view ass a subview of MAINVC.view, it shows up correctly.

Any suggestions on how to get it to show up in my navigation controller?

avery, you're going to need to initialize the navigation controller with the mainMenu as its root view controller, instead of just initializing and then pushing a new view on. It needs that root view controller to work.

mainMenu = [[menuScreenViewController alloc] initWithNibName:@"menuScreenViewController" bundle:nil];
mainMenu.title = @"Menu";
mainNavController = [[UINavigationController alloc] initWithRootViewController:mainMenu];

//ADD MODAL SPLASH SCREEN HERE

[MAINVC.view addSubview:mainNavController.view];

[mainMenu release];
[mainNavController release];

[splashView release];

As the comment above shows, I'll suggest that you initialize this way, and then then add your splash screen to the nav controller as a modalViewController. This will prevent any delay you might have from the mainMenu initialization, when you tap the touchscreen. Then, when the modal view receives a touch, you can call:

[self.parentViewController dismissModalViewControllerAnimated:YES];
