Answer 1

On the view controller that you dont want rotating, make sure that on the:

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation

You return NO;

You are returning it for the tabBar controller, not the actual viewController.

Answer 2

When using a UITabBar controller, all orientation messages goes to the tab bar and stop there.

So, to accomplish what you are trying to do, you have to create a new class inherited from UITabBarController and use that instead.

@interface CustomUITabBarController : UITabBarController

After that you have 2 options to control the orientation of your controllers and both of them you will have touse the shouldAutorotateToInterfaceOrientation selector.

You can either use the tab bar current selected index to return YES or NO for the orientation

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{

    if(self.selectedIndex == 0) {
        return NO;
    } else {
        return YES;
    }

}

OR you could let the controller decide for itself (as you were trying to do before)

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{

    if (self.selectedViewController) {
        return [self.selectedViewController shouldAutorotateToInterfaceOrientation:interfaceOrientation];
    } else {
        return YES;
    }
}
