iOS 6 ViewController正在旋转，但不应该 [英] iOS 6 ViewController is rotating but shouldn't

问题描述

我希望我的几个应用程序视图控制器不在iOS 6.0中旋转。
这就是我在iOS 6中进行旋转所做的事情：

I want several of my app viewcontrollers to not rotate in iOS 6.0. This is what i did to make the rotation in iOS 6 possible:

1。）在应用程序中设置windows rootviewController：didFinishLaunchingWithOptions：

1.) Set the windows rootviewController in application:didFinishLaunchingWithOptions:

self.window.rootViewController = self.tabBarController;

2。）在我的目标中设置支持的接口方向（在XCode中），这样我就可以使用所有方向

2.) Set the "Supported Interface Orientations" in my Target (in XCode) so i can use all orientations

3。）实施新的iOS 6.0轮换功能

3.) Implemented the new iOS 6.0 rotation functionality

- (BOOL) shouldAutorotate {

    return YES;
}


-(NSUInteger)supportedInterfaceOrientations{

    return UIInterfaceOrientationMaskAll;
}

4。）由于某些原因，我将UINavigationController子类化并实现了这些新的功能和使用这个新的NavigationController而不是原来的。

4.) For some reasons, i subclassed the UINavigationController and implemented also these new functionalities and used this new NavigationController in stead of the original one.

到目前为止，一切都很好，所有的视图控制器现在都可以旋转到每个方向。现在我想要几个viewController不旋转，只留在肖像。但是当我在这样的特定视图控制器中设置新的旋转方法时，它仍然会旋转到每个方向：

So far so good, everything works fine and all viewcontrollers are now able to rotate to every orientation. Now i want several viewController to not rotate and only stay in portrait. But when i set the new rotations methods in those specific viewcontrollers like this, it still rotates to every orientation:

- (BOOL) shouldAutorotate {

    return NO;
}


-(NSUInteger)supportedInterfaceOrientations{

    return UIInterfaceOrientationMaskPortrait;
}

同样设置navigationController的旋转功能如上所述不会改变任何东西。 （所有视图控制器都可以旋转到每个方向）

Also setting the navigationController's rotationsfunctionality like above doesn't change anything. (All viewcontrollers can rotate to every orientation)

我做错了什么？

编辑：

同样设置首选的Interfaceorientation不会改变任何内容：

Also setting the preferred Interfaceorientation doesn't change anything:

- (UIInterfaceOrientation) preferredInterfaceOrientationForPresentation {

    return UIInterfaceOrientationMaskPortrait;
}

推荐答案

如果你想要我们所有的导航控制器尊重顶视图控制器，您可以使用类别。我发现它比继承更容易。

If you want all of our navigation controllers to respect the top view controller you can use a category. I've found it easier than subclassing.

@implementation UINavigationController (Rotation_IOS6)

-(BOOL)shouldAutorotate
{
    return [[self.viewControllers lastObject] shouldAutorotate];
}

-(NSUInteger)supportedInterfaceOrientations
{
    return [[self.viewControllers lastObject] supportedInterfaceOrientations];
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
    return [[self.viewControllers lastObject] preferredInterfaceOrientationForPresentation];
}
