UINavigationController + shouldAutoRotate +没有子类化 [英] UINavigationController + shouldAutoRotate + no subclassing

问题描述

我有一个导航驱动的应用程序。我需要该应用程序旋转。 UINavigationController是窗口中的根控制器/视图。我知道（并且已经体验过为什么）UINavigationController的子类是禁止的。我知道我所要做的就是插入：

I have a navigation driven app. I need that app to rotate. The UINavigationController is the root controller/view in the window. I know (and have experienced why) it is a no-no to subclass UINavigationController. I know all i have to do is insert:

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

进入UINavigationController并且它将正常旋转。

into the UINavigationController and it will rotate fine.

所以我的问题是：如何在根视图控制器（UINavigationController）上启用旋转而不进行子类化？

So my question is: how do I enable rotation on the root view controller (UINavigationController) WITHOUT subclassing it?

推荐答案

您需要在 rootViewController 中覆盖此方法，而不是在 UINavigationController 中。

You need to override this method in your rootViewController, not in UINavigationController.

UIViewController *rootViewController = [[MyRootViewController alloc] init];
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:rootViewController];
[rootViewController release];
