IO6不调用 - （BOOL）shouldAutorotate

问题描述

我的应用中有一些观点，我不想支持方向。
在 didFinishLaunchingWithOptions 我添加导航：

I have some views in my app that I don't want to suport orientation.In didFinishLaunchingWithOptions I add navigation:

...
UINavigationController *nav = [[UINavigationController alloc]initWithRootViewController:self.viewController];

    self.window.rootViewController = nav;
    [self.window makeKeyAndVisible];
...

在每个 ViewController中我有 UITabBar （我不知道这是否重要）。

In each ViewController I have UITabBar (I don't know if this is important).

在第一个视图控制器中我补充说：

In the first view controller I add:

-(BOOL)shouldAutorotate {
        return NO;
    }

    - (NSUInteger)supportedInterfaceOrientations {
        return UIInterfaceOrientationMaskPortrait;
    }

supportedInterfaceOrientations 被调用在视图加载但 shouldAutorotate 没有调用我旋转设备。

我在这里缺少什么？

supportedInterfaceOrientations is called at the view loading but shouldAutorotate doesn't call as I rotate device.
What am I missing here?

推荐答案

这是因为 UITabBarcontroller 和 UINavigationController 都不是将shouldAutorotate传递给它的可见视图控制器。为了解决这个问题，你可以从那里继承任何的UITabBarController或UINavigationController的转发shouldAutorotate：

It's because neither UITabBarcontroller nor UINavigationController is passing shouldAutorotate to its visible view controller. To fix that you may subclass either UITabBarController or UINavigationController and forward shouldAutorotate from there:

在你的子类的UITabBarController添加：

In your subclassed UITabBarController add:

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

在你的子类UINavigationController中添加：

In your subclassed UINavigationController add:

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