iOS 6 AutoRotate在UiNavigationController中

Question

我的应用程序中有UiNavigationController.我希望只有一个屏幕可以旋转,所以我放入这个类:

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

-(BOOL)shouldAutorotate {
    return YES;
}

-(NSInteger)supportedInterfaceOrientations {
    return UIInterfaceOrientationMaskAll;
}

但发生的问题是在ecery屏幕上应用程序旋转发生.我怎么能禁用它？

对于iOS 6,我在我的应用程序中使用以下代码,它允许您单独指定每个viewcontroller的旋转:

AppDelegate.m -

- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window{NSUInteger orientations =UIInterfaceOrientationMaskAllButUpsideDown;
if(self.window.rootViewController){
UIViewController *presentedViewController = [[(UINavigationController *)self.window.rootViewController viewControllers] lastObject];
orientations = [presentedViewController supportedInterfaceOrientations];
}
return orientations;
}

ViewController.m -

- (NSUInteger)supportedInterfaceOrientations{
return UIInterfaceOrientationMaskPortrait;
}
