Answer 1

在确实收到回复中添加这些代码行，它对我有用

 let storyboard = UIStoryboard(name: "Main", bundle: nil)
    let navigationController = self.window?.rootViewController as? UINavigationController
    let destinationController = storyboard.instantiateViewController(withIdentifier: "YourIdentifierName") as? YourViewController
    navigationController?.pushViewController(destinationController!, animated: false)
var presentedVC = self.window?.rootViewController
        while (presentedVC!.presentedViewController != nil)  {
            presentedVC = presentedVC!.presentedViewController
        }

Answer 2

func redirectToSpecificVC() {
let mainStoryboard : UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
let initialViewController: UIViewController = mainStoryboard.instantiateViewController(withIdentifier: "versesVC") as UIViewController
self.window = UIWindow(frame: UIScreen.main.bounds)
self.window?.rootViewController = initialViewController
self.window?.makeKeyAndVisible()}

使用这些函数重定向到特定的视图控制器
