我正试图在我的游戏上创建一个暂停屏幕.我在故事板中添加了一个'PauseScreen'viewController,故事板ID和Restoration ID设置为"PauseScreenID",并移动到暂停屏幕我已在"GameScene"中创建了该功能:

func pauseSceenTransition(){

    let viewController = UIStoryboard(name: "Main", bundle:nil).instantiateViewControllerWithIdentifier("PauseScreenID") as UIViewController

    let currentViewController = (UIApplication.sharedApplication().delegate as AppDelegate)

    currentViewController.window?.rootViewController?.presentViewController(viewController, animated: false, completion: nil)
}

但是当它被调用时,我得到错误:

警告:尝试在< AppName .StartScreenViewController:0x7fae61f79980>上显示< AppName .PauseScreen:0x7fae61fe5ff0>,其视图不在窗口层次结构中!

"StartScreenViewController"是我的开始屏幕的视图控制器,是初始视图控制器.然后转到"GameScene",这是"PauseScreen"需要去的地方.如果我将初始视图控制器设置为"GameViewController"/"GameScene",它可以工作,所以我认为我需要更改第二行:

let currentViewController = (UIApplication.sharedApplication().delegate as AppDelegate)

所以它在"GameViewController"上呈现"PauseScreen",而不是"StartScreenViewController",但我不知道该怎么做.
