Rotating view controllers in the tab bar controller hierarchy & # 8594; Navigation Controller & # 8594; View controller

Question

My application has a view controller hierarchy configured as follows:

UITabBarController
    |
    UINavigationController
    |  |
    |  UIViewController
    |
    UINavigationController
       |
       UIViewController

All my view controllers that are inside this hierarchy override the method:

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation

and return YES- therefore, the view controller must be able to rotate before any rotation - even upside down.

However, in this setting, none of the view controllers will spin successfully. I got the impression that the navigation controllers and tab bars would rotate if their controllers represented rotation.

Why won't my view controllers spin?

Answer 4

Subclass of UITabBarController as well as UINavigationController. It works using xCode 4.4.

Answer 5

I developed an extension that allows you to do this without a subclass of UITabBarController https://github.com/piercifani/TabBarBetterRotation
