SPA*_*SPA 8 iphone storyboard uinavigationcontroller subclassing uiinterfaceorientation
我在界面构建器中使用故事板使用Xcode菜单'Editor ... Embed in ... Navigation Controller'.
似乎在iOS 6中你必须将UINavigationController子类化为允许所有方向
- (NSUInteger)supportedInterfaceOrientations {
return (UIInterfaceOrientationMaskAll );
}

但是,如何将UINavigationController与故事板应用程序子类化,因为代码中没有对它的引用?

您可以从故事板中选择导航控制器场景的导航控制器:

然后使用右侧的身份检查器来更改类:

例如,将"Class"更改为MyCustomNavigationController,然后在项目中创建一个名为的新类MyCustomNavigationController:
MyCustomNavigationController.h:
#import <UIKit/UIKit.h>
@interface MyCustomNavigationController : UINavigationController

- (NSUInteger)supportedInterfaceOrientations {
return UIInterfaceOrientationMaskAll;
}
... any other methods you want ...
