ios - Cloud Firestore 身份验证 iOS

Question

我是 iOS 开发的新手(边走边学)，我正在使用 Cloud Firestore 通过电子邮件/密码对用户进行身份验证。我正在尝试进行简单的电子邮件和密码身份验证。我使用了文档中的数据库规则之一，我认为我不必在规则中创建集合和文档。我已经测试了我与数据库的连接，所以这也不是问题。我到目前为止的代码如下:

import UIKit
import Firebase


class SignUpViewController: UIViewController {

    //Outlets
    @IBOutlet weak var firstNameText: UITextField!
    @IBOutlet weak var lastNameText: UITextField!
    @IBOutlet weak var emailText: UITextField!
    @IBOutlet weak var passwordText: UITextField!
    @IBOutlet weak var signUpButton: UIButton!


    override func viewDidLoad() {
        super.viewDidLoad()
    }

    @IBAction func signUpButtonTapped(_ sender: Any) {
        guard let firstName = firstNameText.text,
        let lastName = lastNameText.text,
        let email = emailText.text,
        let password = passwordText.text else { return }

        Auth.auth().createUser(withEmail: email, password: password) { (authResult, error) in
            if let error = error {
                debugPrint("Error creating user: \(error.localizedDescription)")
            }
            let changeRequest = Auth.auth().currentUser?.createProfileChangeRequest()
            changeRequest?.displayName = firstName
            changeRequest?.commitChanges(completion: { (error) in
                if let error = error {
                    debugPrint(error.localizedDescription)
                }
        })
            guard let userId = authResult?.user else { return }
            Firestore.firestore().collection(USERS_REF).document(userId).setData([
                USERNAME : firstName,
                DATE_CREATED : FieldValue.serverTimestamp()
                ], completion: { (error) in

                    if let error = error {
                        debugPrint(error.localizedDescription)
                    } else {
                        self.dismiss(animated: true, completion: nil)
                    }
            })
        }
    }



}

但是我得到了错误:

• 无法使用类型为“([String : Any]，完成:((Error?) -> Void)?)”的参数列表调用“setData”

有什么我没有做的吗？有人可以帮助进行此电子邮件/密码身份验证吗？

Answer 1

首先检查变量的命名方式是否正确。在 swift 中，我们使用驼峰命名法。

其次，您尝试将 textField 对象分配给字典中的密码。

第三，您已尝试在登录操作之外打印并执行 segue。考虑编辑您的代码:

  @IBAction func SMLoginTapped(_ sender: Any) {
     print("Login button tapped!")
     guard let emailText = EmailTextField.text, !emailText.isEmpty else { return }
     guard let passwordText = PasswordTextField.text, !passwordText.isEmpty else { return }
     let saveData: [String: Any] = ["email": emailText, "password": passwordText]
     docRef.setData(saveData) { (error) in
        if let error = error {
            print("Oh no! Got an error: \(error.localizedDescription)")
        } else {
            print("Data has been saved to Firestore!")
            self.performSegue(withIdentifier: "SecondViewSegue", sender: self)
        }
    }
}
