我目前正在使用 Swift 3、SpriteKit 和 Xcode 8 beta 开发游戏。我正在尝试通过 info.plist 从主屏幕实现静态 3D Touch 快速操作。目前，这些动作从主屏幕看起来很好，但不要转到正确的 SKScene - 转到初始场景或最后打开的场景（如果应用程序仍然打开），这意味着场景没有被更改。我尝试了各种在 switch 语句中设置场景的方法，但似乎没有一种方法可以正常显示 SKScene，因为该行window!.rootViewController?.present(gameViewController, animated: true, completion: nil) 仅适用于 UIViewController。
此代码的各个部分来自各种教程，但通过我的调查，我相当确定损坏的部分是正在呈现的场景（除非我错了），因为如果部分损坏，它甚至不应该加载任何场景.
有什么方法可以从 AppDelegate 呈现 SKScene 或根据 switch 语句设置开场场景？
