shouldAutoRotate Method Not Called in iOS6
提问by GuybrushThreepwood
I have a UIViewControllerdetail view which is pushed from a UITableViewin a UINavigationController. In the UIViewControllerI add a number of subviews (e.g a UITextView, UIImageView).
我有一个UIViewController从 a UITableViewin a推送的详细视图UINavigationController。在UIViewControllerI 添加多个子视图（例如 a UITextView, UIImageView）。
In iOS5I used this code to stop autorotation if my picture view was enlarged :
在iOS5我用这个代码，以停止自转，如果我的图片视图被扩大了：
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
// Return YES for supported orientations
if (scrollView.isZoomed) {
return NO;
}
else {
return YES;
}
}
}
I am trying to achieve the same thing under iOS6using :
我试图在iOS6using下实现同样的事情：
- (BOOL)shouldAutorotate {
return FALSE;
}
However this method is never called and the app continues rotating.
然而，这个方法永远不会被调用，应用程序会继续旋转。
Can anyone help ?
任何人都可以帮忙吗？

If you have a Navigation Controller managing these views, the shouldAutorotatemethod won't be called. You would have to subclass UINavigationControllerand override methods shouldAutorotateand supportedIntervalOrientations.
如果您有一个 Navigation Controller 管理这些视图，则不会调用shouldAutorotate方法。您必须继承 UINavigationController并覆盖方法shouldAutorotate和supportedIntervalOrientations。
From the docs:
从文档：
Now, iOS containers (such as UINavigationController) do not consult their children to determine whether they should autorotate
现在，iOS 容器（例如 UINavigationController）不会咨询他们的孩子来确定他们是否应该自动旋转

As mentioned below by Lomax, subclassing UINavigationController is discouraged by Apple. You should try a category instead (this SO question explains it well):
正如 Lomax 在下面提到的，Apple 不鼓励子类化 UINavigationController。你应该尝试一个类别（这个 SO question 很好地解释了它）：
@implementation UINavigationController
-(BOOL)shouldAutorotate
{
// your code
}
-(NSUInteger)supportedInterfaceOrientations
{
(...)
}
@end
