Rotate interface with UITabBarController

I've created a new "Tab Bar project" with the new Xcode 4.2. The "new" way to work with UITabBar is different: Xcode doesn't create a xib file (with the UITabBarController), but it does everything via code. Ok, let's do it.

So my code in didFinishLaunchingWithOptions is this:

UIViewController *viewController1, *viewController2, *viewController3;
UINavigationController *nav1, *nav2, *nav3;

if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {

    viewController1 = [[gemboy_iphone alloc] initWithNibName:@"vc1" bundle:nil];
    viewController2 = [[concerti_iphone alloc] initWithNibName:@"vc2" bundle:nil];
    viewController3 = [[discografia_iphone alloc] initWithNibName:@"vc3" bundle:nil];

    nav1 = [[UINavigationController alloc] initWithRootViewController:viewController1];
    nav2 = [[UINavigationController alloc] initWithRootViewController:viewController2];
    nav3 = [[UINavigationController alloc] initWithRootViewController:viewController3];

}
else {
  //same thing for the iPad version
}
self.tabBarController = [[UITabBarController alloc] init];
self.tabBarController.viewControllers = [NSArray arrayWithObjects:nav1, nav2, nav3, nil];
self.window.rootViewController = self.tabBarController;
[self.window addSubview:self.splash.view];
[self.window makeKeyAndVisible];
return YES;

And it works.

My three .m files vc1.m, vc2.m and vc3.m (and also my iPad UIViewControllers) has this method

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
     return YES;
}

The problem is that when I rotate the iPhone, it rotates only the status bar, and not the TabBarController!

Do you know why? Thanks

You absolutely do not have to subclass UITabBarController, nor should you.

A tab bar controller will auto-rotate just fine IF all of its view controllers implement shouldAutorotateToInterfaceOrientation and return YES for the same orientations.

If you create a new project in Xcode 4.2 with the Tabbed Application template, you will see that it auto-rotates just fine.
