Swift 和 Firebase 数据库 - 调用中缺少参数标签“andPriority”

Question

当用户在应用程序中注册时，下面的代码用于更新我的 firebase 数据库，假设在数据库中对用户进行身份验证并保存一个布尔值。执行此操作时出现以下错误（见下文）。

@IBAction func signupPressed(_ sender: UIButton) {

        Auth.auth().createUser(withEmail: emailEntryField.text!, password: passwordEntryField.text!) { (user, error) in
            if error == nil {

                //Show SVProgressHUD
                SVProgressHUD.show()

                //save User to Database
                let newUserInfo : [String:Any] = ["email":self.emailEntryField.text!, "state":true]
                self.ref.child("users").child(user?.user.uid).setValue(newUserInfo, withCompletionBlock: { (error, ref) in
                    print("New User Saved")
                }

                //Dismiss SVProgressHUD
                SVProgressHUD.dismiss()

                //move to info view controller
                self.performSegue(withIdentifier: "signupToInfo", sender: self)

            } else {

                print("Signup Unsuccessul")
                let alertController = UIAlertController(title: "Error", message: error?.localizedDescription, preferredStyle: .alert)
                let defaultAction = UIAlertAction(title: "OK", style: .cancel, handler: nil)

                alertController.addAction(defaultAction)
                self.present(alertController, animated: true, completion: nil)

            }
        }
    }

块后面少了一个)

self.ref.child("users").child(user?.user.uid).setValue(newUserInfo, withCompletionBlock: { (error, ref) in
  print("New User Saved")
}

在最后加上)，像这样

self.ref.child("users").child(user?.user.uid).setValue: newUserInfo, withCompletionBlock: { (error, ref) in
  print("New User Saved")
})

希望对你有帮助
