Seg没有在ViewDidLoad / ViewDidAppear中开始

Question

我尝试在我的ViewDidLoad / ViewDidAppear方法中运行Segue。我在两种方法中尝试过但它没有用。请参阅我附带的代码：

      super.viewDidAppear(false)
    Auth.auth().addStateDidChangeListener { auth, user in
        if (user?.isEmailVerified)!{
            print("started")
            self.performSegue(withIdentifier: "gotoMoin", sender: nil)
        }else  {

        }
    }
}

邮件已经过验证，因此我获得了“已启动”输出

Answer 1

我使用以下代码解决了它：

 let user = Auth.auth().currentUser
    if (user?.isEmailVerified)!{
        self.performSegue(withIdentifier: "gotoMoin", sender: nil)
    }else{
        Auth.auth().currentUser?.reload()
    }
}
