UITabBarController + autorotation

问题

I created an application with a TabBarController using IB who have 4 TabBarItems and so display 4 differents ViewControllers. To allow a landscape orientation I must add this code in all of my ViewController:

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
     return (interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown ? NO : YES);
}

The problem is I don't want for example the secondViewController to autorotate, How can I do that? Because everytime I delete the code above in one of my ViewController, every ViewControllers not rotate anymore.

Thanks

Leave the code in there, but you'll want to do one of two things:

1. Disable the non-rotatable tab when showing landscape view OR
2. In the viewWillAppear or viewDidAppear for that tab, force rotation to portrait.

eg:

[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationPortrait animated:YES]
