Pushing a navController not supported, in a UITabBarController

Just created a new project and I have 4 view controllers which I add to UINavigationController like this:

WatchViewController *first = [[WatchViewController alloc] init];
BetViewController *second = [[BetViewController alloc] init];
Settings *third = [[Settings alloc] init];
Account *forth = [[Account alloc] init];

UINavigationController *navFirst = [[UINavigationController alloc]initWithRootViewController:first];
UINavigationController *navSecond = [[UINavigationController alloc]initWithRootViewController:second];
UINavigationController *navThird = [[UINavigationController alloc]initWithRootViewController:third];
UINavigationController *navForth = [[UINavigationController alloc]initWithRootViewController:forth];

Load them into an array:

NSArray *viewArray = [[NSArray alloc] initWithObjects:navFirst, navSecond, navThird, navForth, nil];

Load the tab bar and window:

self.tabController = [[UITabBarController alloc] init];
[self.tabController setViewControllers:viewArray animated:YES];

[self.window setRootViewController:self.tabController];

self.window.backgroundColor = [UIColor whiteColor];
[self.window makeKeyAndVisible];

All the view are just standard views. When I try and run the app it responds with :

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Pushing a navigation controller is not supported'

I can't figure out what I've missed. Any help?

Sorry, I had annoyingly subclassed UINavigationController instead of UIViewController. I hadn't picked up on it because if I didn't use the NavControllers the App would run fine, add the nav controllers and it broke. :(

Why don't you try UINavigationController inside UITabBarController by setting controllers in xib. It worked for me.

Try this one:

WatchViewController *first = [[WatchViewController alloc] initWithNibName:@"WatchViewController" bundle:Nil];
BetViewController *second = [[BetViewController alloc] initWithNibName:@"BetViewController" bundle:Nil];
Settings *third = [[Settings alloc] initWithNibName:@"Settings" bundle:Nil];
Account *forth = [[Account alloc] initWithNibName:@"Account" bundle:Nil];

/*Your View Navigation Stuff and your viewArray*/

self.tabController.viewControllers = viewArray;

Don't create 4 navigation controllers. Controllers that are needed to navigate through should be assigned to viewControllers property in UINavigationController via setViewControllers:animated: method.

You should create 1 NavigationController and add array of 4 UIViewControllers.

A very good example is given here: example and don't forget to look here UINavigationClass
