iOS 5.0模式视图不旋转（故事板）

Question

I use story boards. In every view controler I want to rotate I included this method like this:

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

in iOS 6 it rotates just fine to the proper views I have for landscape and portrait in my story boards.

in iOS 5 the parent view contoller rotates but the modals don't rotate while they are on the screen, they only rotate before they are on the screen but never during. So when a user changes orientation it remains the same. A parent will change while on screen but the modal will take on the orientation the parent had but will not change while on screen. How do I get my modal views to work like iOS 6 where they will rotate when on the screen. The modal view were created via the storyboard.

Edit*

When I do a popover to a modal, the modal doesn't rotate. How can I fix this?

Answer 1

Rotation is handled differently in iOS5 and iOS6. I use the below code to support both versions.

// iOS5
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return YES;
}

// iOS6
- (NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskAll;
}

- (BOOL)shouldAutorotate
{
    return YES;
}

shouldAutorotateToInterfaceOrientation: is deprecated in iOS6.
