在选项卡栏控制器的层次结构内旋转视图控制器->导航控制器->查看控制器

我的应用程序具有如下设置的视图控制器层次结构:

My app has a view controller hierarchy set up like this:

UITabBarController
    |
    UINavigationController
    |  |
    |  UIViewController
    |
    UINavigationController
       |
       UIViewController

此层次结构中的所有视图控制器都覆盖该方法:

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

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation

并返回YES-因此，视图控制器应该能够旋转至任何旋转-甚至可以上下颠倒.

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

但是，在此设置中，没有一个视图控制器成功旋转.我的印象是，如果导航和标签栏控制器的视图控制器响应旋转，它们将旋转.

However, within this setup none of the view controllers successfully rotate. I was under the impression that navigation and tab bar controllers would rotate if their view controllers respond to rotating.

为什么我的视图控制器不旋转?

Why won't my view controllers rotate?

我能够使它们旋转的唯一方法是对UINavigationController进行子类化并覆盖它的shouldAutorotate方法，但这对我来说是不必要的，我想知道是否有一些我想念的东西工作.

The only way I've been able to get them to rotate is by subclassing UINavigationController and overriding it's shouldAutorotate method, but this feels unnecessary to me and I was wondering if there's something I've missed to make this work.

根据用户体验编码方法:

According to the User Experience Coding How-to:

如果还使用工具栏，则每个工具栏项的视图控制器必须实现shouldAutorotateToInterfaceOrientation:方法，并为要支持的每个方向返回YES.如果您有用于工具栏项目的导航控制器，则该导航控制器的根视图控制器必须实现shouldAutorotateToInterfaceOrientation:方法并返回YES.

If you are also using a toolbar, the view controller for each toolbar item must implement the shouldAutorotateToInterfaceOrientation: method and return YES for each of the orientations you wish to support. If you have a navigation controller for a toolbar item, the root view controller of that navigation controller must implement the shouldAutorotateToInterfaceOrientation: method and return YES.

上面写着工具栏"-但是我认为这是一个错字，可能应该是标签栏".

It says 'toolbar' - but I think this is a typo and is probably supposed to be 'tab bar'.

因此，看来我正确实现了这一点，但我的控制器仍然无法自动旋转.

So it seems that I'm implementing this correctly, yet my controllers still do not auto rotate.
