iOS 8：没有故事板，自动旋转无法运行 [英] iOS 8: Autorotation is not working without storyboard

问题描述

所以我试图启动一个没有Storyboard的项目，我似乎无法弄清楚为什么UIWindow没有将自动旋转命令传递给根视图控制器。通过故事板，自动旋转起作用。如果我以编程方式创建窗口，则自动旋转不起作用。

So I am trying to start a project w/o Storyboards and I can't seem to figure out why the UIWindow is not passing autorotation commands to the root view controller. With storyboards, the autorotation works. If I create the window programmatically, autorotation does not work.

这是我在App Delegate中实例化窗口的方式：

This is how I instantiate the window in the App Delegate:

window = UIWindow(frame: UIScreen.mainScreen().bounds)
if let window = window {
    window.backgroundColor = UIColor.whiteColor()
    window.makeKeyAndVisible()

    let nc: SignInViewController = UIStoryboard(name: "Main", bundle: nil)
            .instantiateViewControllerWithIdentifier("SignInViewController") as SignInViewController
    window.rootViewController = nc
}

谢谢！

推荐答案

标记的答案是降级到XCode 6.0.1 - 我不推荐它。

Marked answer is to downgrade to XCode 6.0.1 - I do not recommend it.

1）如果你不要使用故事板 （本主题的答案!!）

转到 - >项目名称 - >目标 - >项目名称 - >部署信息 - > 主界面 - >将其清空

Go to -> Project Name -> Targets -> Project Name -> Deployment Info -> Main Interface -> Make it Empty

2）如果您使用故事板（不是主要答案）

2) In case you use storyboards (not the main answer)

您的AppDelegate应该看起来像......

your AppDelegate should look like ...

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool 
{
    return true
}
