iOS 6错误：当导航控制器用作窗口根时未调用supportedInterfaceOrientations [英] iOS 6 bug: supportedInterfaceOrientations not called when nav controller used as window root

问题描述

在我的mainwindow.xib中，我有一个navigationcontroller。在（作为子项）之上我有另一个viewcontroller（homeviewcontroller）。

在笔尖中我将窗口的rootviewcontroller设置为此导航控制器。

这部署到应用程序存储和工作完美。

由于升级到ios6 sdk我遇到了方向问题 - 基本上使用这种设计我的homeviewcontroller的supportedInterfaceOrientations方法在运行我的应用程序时不会被调用ios 6设备/模拟器。

为了解决这个问题，我需要将homeviewcontroller设置为窗口的rootviewcontroller，但这不是我想要的 - 我需要导航控制器。 / p>

如何解决ios6中这个烦人的错误？

更新：

我也尝试过以编程方式执行此操作 - 它仍然无效。

   - （BOOL）应用程序：（UIApplication *）应用程序didFinishLaunchingWithOptions：（NSDictionary *）launchOptions 
 {
 HomeViewController * homeVC = [[HomeVi] ewController alloc] init]; 
 UINavigationController * navController = [[UINavigationController alloc] initWithRootViewController：homeVC]; 
 [self.window setRootViewController：navController]; 
 
 [self.window makeKeyAndVisible]; 
 
返回YES; 
} 
  

解决方案

你需要继承UINavigationController和在那里覆盖supportedInterfaceOrientations。

In my mainwindow.xib I have a navigationcontroller. On top of (as a sub item) I have another viewcontroller(homeviewcontroller).

In the nib I have set the window's rootviewcontroller to be this navigationcontroller.

This is deployed to the app store and works perfectly.

Since upgrading to ios6 sdk I am getting orientation issues - basically with this design the supportedInterfaceOrientations method of my homeviewcontroller does not get called when running my app in ios 6 device/simulator.

In order to fix this issue I need to set homeviewcontroller as the window's rootviewcontroller however this is not what I want - I need the navigationcontroller.

How do I get around this annoying bug in ios6?

Update:

I have also tried doing this programmatically - it still doesn't work.

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{        
    HomeViewController *homeVC = [[HomeViewController alloc]init];
    UINavigationController *navController = [[UINavigationController alloc]initWithRootViewController:homeVC];
    [self.window setRootViewController:navController];

    [self.window makeKeyAndVisible];

    return YES; 
}

解决方案

You need to subclass UINavigationController and override supportedInterfaceOrientations there.
