ios - 如何在 Delegate 中引用其他 ViewController 而不仅仅是 root

Question

我正在尝试创建 Siri 快捷方式，并且希望该快捷方式能够转到不同的 ViewController 而不仅仅是根目录。这是怎么做到的？以下是当前的 App Delegate 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


        }

你可以使用这个代码AppDelegate，它就可以了:

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
