Here is a sample code from Apple to create tab bar programmatically:

- (void)applicationDidFinishLaunching:(UIApplication *)application {
   tabBarController = [[UITabBarController alloc] init];

   MyViewController* vc1 = [[MyViewController alloc] init];
   MyOtherViewController* vc2 = [[MyOtherViewController alloc] init];

   NSArray* controllers = [NSArray arrayWithObjects:vc1, vc2, nil];
   tabBarController.viewControllers = controllers;

   // Add the tab bar controller's current view as a subview of the window
   [window addSubview:tabBarController.view];
}

It's worth noting that a tab bar controller implemented inside a navigation controller is unsupported by Apple. From the same doc linked to by vodhkang above:

Note: Although a navigation controller can be embedded inside a tab, the reverse is not true. Presenting a tab bar interface from within a navigation interface is potentially confusing for users. A navigation interface uses one or more custom view controllers to present an interface focused on one goal, which is usually the management of a specific type of data. By contrast, the tabs of a tab bar interface can reflect completely different purposes in an application and need not be related in any way. In addition, pushing a tab bar controller on a navigation stack would cause the tabs to be displayed for that screen only and not for any others.

So instead of using UITabBarController consider implementing a tab bar with a UIViewController as the tab bar's delegate.
