swift - 在 Firebase 中保存用户名 - Swift

Question

我的注册表中有三个文本字段。 Firebase SignUp 方法使用用户的电子邮件 ID 和密码来创建新用户。但我也想根据他们输入的内容保存用户名。

我当前的代码是；

@IBAction func registerPressed(_ sender: Any) {

    SVProgressHUD.show(withStatus: "Setting you up")
    dismissUIElements(value: false)

    let currentUserName = userName.text
    if currentUserName?.isEmpty == false {
        FIRAuth.auth()?.createUser(withEmail: emailTextField.text!, password: passwordTextField.text!, completion: { (user, error) in

            if error != nil {
                print(error!)

                SVProgressHUD.dismiss()

                self.dismissUIElements(value: true)

            } else {
                print("Registration Successful!")

                SVProgressHUD.dismiss()
                self.dismissUIElements(value: true)

                self.performSegue(withIdentifier: "goToSelectionFromRegister", sender: self)
            }
        })
    }
    else {
        SVProgressHUD.dismiss()

        SVProgressHUD.showError(withStatus: "Please enter your name!")
        SVProgressHUD.dismiss(withDelay: 1)
        self.dismissUIElements(value: true)
    }

}

您需要一个函数来注册用户，然后在 Firebase 中为该用户创建子项。

let databaseRef=//your path to users.     

func registerUser(userUsername userName:String, userEmail email:String, userPassword password: String, userCreationComplete: @escaping (_ status: Bool, _ error: Error?) -> ()) {
    Auth.auth().createUser(withEmail: email, password: password) { (user, error) in
        guard let user = user else {
            userCreationComplete(false, error)
            return
        }

        let userData = ["userName": userName.text] as [String : Any]

        ref.child(user.uid).updateChildValues(userData)

        userCreationComplete(true, nil)

    }
}

然后从 registerPressed() 中调用该函数并将文本字段值传递给它，但要确保它们都不为空。
