UITabBar with UINavigationController in code

Question

Hi Everyone,

I've currently got a UITabBar with 5 screens calling UIViews. That part works fine but I want to put in a UINavigationController in a couple of them. I have found a few tutorials that work fine but all of them implement it in IB and I want to avoid that if possible.

I'm lost as to where to implement the UINavigationController, should I do it in the App Delegate with the UITabBar and call the navigation controller from the UIView or should I create it in the UIView class?

I've tried about 8 different ways and always ends up with either the Navbar not working, no nav bar at all or the app crashing.

Currently I create the tab bar like this:

tabBarController = [[UITabBarController alloc] init];
ScreenA *screenA = [[ScreenA alloc] initWithNibName:@"ScreenA" bundle:nil];
//more here
tabBarController.viewControllers = [NSArray arrayWithObjects:screenA, ...., nil];
[window addSubview:tabBarController.view];

And in the initWithNibName I have this:

self.title = @"Screen A";
self.tabBarItem.image = [UIImage imageNamed:@"someImage.png"];

Thanks for any help you can offer.
