Tabbar controller in a navigation stack is complicated. Since each tab controller can have also navigation controller itself.

Have a WindowManager class. It should own both
– FirstViewController and
– TabbarController

All components and the UITabbarControllers themselves should be instantiated in the WindowManager class.
Its init may have code like this, make similar for two tabbarcontrollers.

self.tabBarController = [[UITabBarController alloc] init];
    self.controllers = [[NSMutableArray alloc] init];

// initialize the view controllers and navigation controllers for the tab bar

self.friendsVC = [[FriendsVC alloc] initWithNibName:@"FriendsView" bundle:nil];
UINavigationController *friendsNVC = [[UINavigationController alloc] initWithRootViewController: friendsVC];
friendsNVC.navigationBar.barStyle = UIBarStyleBlack;
[controllers addObject:friendsNVC];  
[friendsNVC release];

self.paymentsVC = [[PaymentsVC alloc] initWithNibName:@"PaymentsView" bundle:nil];
UINavigationController *paymentsNVC = [[UINavigationController alloc] initWithRootViewController: paymentsVC];
paymentsNVC.navigationBar.barStyle = UIBarStyleBlack;
[controllers addObject:paymentsNVC];
[paymentsNVC release];  

tabBarController.viewControllers = controllers;
tabBarController.selectedIndex = 0; 
tabBarController.delegate = self;

self.view = tabBarController.view;

In the WindowManager, you can have two methods like,

[WindowManager showViewController] and
[WindowManager showTabbarController].

- showViewController {
  //Initiate View controller and use [self.window addSubView:vc.view];
}

- showTabbarController {
  // initiate the tabbar manager
}

You can have a “back” button on top of your first tabbar controller left side, to call the

[WindowManager showViewController];
