UIWindow状态栏旋转

Question

I have an application where I have a use case for two UIWindow instances. The first instance runs all normal app interactions, but I need to be able to present a view controller above everything else regardless of what the user is doing in the application, without user interaction.

I have the second window working and presenting fine. In this view controller, I only support portrait mode (though other parts of the app support landscape). I've tried to block rotation using these methods in the rootViewController of the window:

override func supportedInterfaceOrientations() -> UIInterfaceOrientationMask {
  return [.Portrait]
}

override func shouldAutorotate() -> Bool {
  return false
}

That successfully prevents the device from rotating the view controller, but it still allows the status bar to rotate. I'd like to prevent the status bar from rotating as well. I tried adding the following to my AppDelegate

func application(application: UIApplication, supportedInterfaceOrientationsForWindow window: UIWindow?) -> UIInterfaceOrientationMask {
  if let _ = window as? MyTopWindow {
    return [.Portrait]
  } else {
    return .All
  }
}

However that hasn't worked either. The status bar still rotates.

I've seen the question below and tried to implement the solution but it's not working for my case: Status bar rotates separated from UIWindow

Edit

Here's the code where I create the UIWindow :

self.callManagementWindow = ActiveCallManagementWindow(frame: UIScreen.mainScreen().bounds)
self.callManagementWindow.rootViewController = primaryViewController
self.callManagementWindow.hidden = false
self.callManagementWindow.makeKeyAndVisible()

Answer 1

前段时间我也有两个窗口和旋转的问题，如果我rootViewController ，你需要覆盖第一个UIWindow rootViewController的supportedInterfaceOrientations()和rootViewController shouldAutorotate()以及第二个

Answer 2

您可以在primaryViewController的viewDidAppear中尝试这个：

[UIApplication sharedApplication].statusBarOrientation = UIInterfaceOrientationPortrait;

Answer 3

In my case, I setup UIWindow in code, while also specifying Main storyboard in Info.plist

<key>UIMainStoryboardFile</key>
    <string>Main</string>

The Main.storyboard has a simple initial ViewController (this ViewController does not specify any orientations)

The solution is removing the UIMainStoryboardFile (in Info.plist or in General -> Targets -> Deployment Info -> Main Interface)
