如何在委托中引用其他视图控制器，而不仅仅是根

Question

我正在尝试创建一个Siri快捷方式，我希望快捷方式转到不同的ViewController，而不仅仅是根。这是怎么做到的？以下是当前的应用委托代码。

func application(_ application: UIApplication, continue userActivity: NSUserActivity, restorationHandler: @escaping ([Any]?) -> Void) -> Bool {
            print(userActivity.activityType)//com.myvisionapps.Meditate.begin
            if(userActivity.activityType == "com.myvisionapps.Meditate.begin") {
                if let controller = window?.rootViewController as? ViewController {
                }
            }
            return false

        }

您可以使用此代码AppDelegate及其消失的okey：

let mainStoryboardIpad : UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
let initialViewControlleripad : yourViewController = mainStoryboardIpad.instantiateViewController(withIdentifier: "yourViewControllerIdentifire") as! yourViewController
self.window = UIWindow(frame: UIScreen.main.bounds)
self.window?.rootViewController = initialViewControlleripad
self.window?.makeKeyAndVisible()
// now you can use initialViewControlleripad to access to your references in your ViewController
