按下uiAlert按钮后以编程方式推送到新的viewController

Question

我想知道是否可以在按下UiAlertController中的按钮后将其推送到newViewController

我的代码看起来像

 @objc func handleAcceptRequest() {
    let user = self.user
    let username = user?.name

    let alert = UIAlertController(title: "Are you Sure? ",message:" Would you like to accept \(username!) to complete your job?", preferredStyle: UIAlertController.Style.alert)

    let cancelButton = UIAlertAction(title: "Cancel", style: .default, handler: {(_ action: UIAlertAction) -> Void in
           print("you pressed cancel button")
       })

    let continueButton = UIAlertAction(title: "Continue", style: .default, handler: {(_ action: UIAlertAction) -> Void in

        let vc = viewController()
        let navController = UINavigationController(rootViewController: vc)

           print("you pressed Continue")

       })



    continueButton.setValue(GREEN_Theme, forKey: "titleTextColor")
    cancelButton.setValue(UIColor.red, forKey: "titleTextColor")
    alert.addAction(cancelButton)
    alert.addAction(continueButton)
    self.window?.rootViewController?.present(alert, animated: true, completion: nil)

  }

我仅想按Continue按钮，但如果我叫现在的话就显示VC

// self.present（navController，动画：true，完成：nil）

在continueButton内，出现错误，使用未解析的标识符'present'

是否可以通过这种方式推送newVC？

Answer 1

self.window?.rootViewController?. present(navController, animated: true, completion: nil)

这是因为在其中没有要显示viewController的navigationController。 viewController出现在navigationController上。
