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
}
