Question

我正在使用Firebase框架使用标准的用户名和密码。

出现了登录界面，但现在不再显示。

Google sign UI仍然可以显示并正常工作。

它看起来如下：

用于复制问题的代码如下：

import UIKit
import Firebase
import FirebaseUI

class ViewController: UIViewController {

    private var handle: AuthStateDidChangeListenerHandle?
    @IBOutlet weak var userLbl: UILabel!

    @IBAction func logout(_ sender: Any) {
        let firebaseAuth = Auth.auth()
        do {
            try firebaseAuth.signOut()
        } catch let signoutError as NSError {
            debugPrint("Error signing out: \(signoutError)")
        }
    }

    override func viewDidLoad() {
        super.viewDidLoad()
        handle = Auth.auth().addStateDidChangeListener({ (auth, user) in
            if user == nil {

                if let authUI = FUIAuth.defaultAuthUI() {
                    authUI.delegate = self

                    let providers: [FUIAuthProvider] = [
                        FUIGoogleAuth()
                    ]
                    authUI.providers = providers

                    let authViewController = authUI.authViewController()
                    self.present(authViewController, animated: true, completion: {})
                }
            }
            else{
                self.userLbl.text = user?.displayName
            }
        })
    }
}

extension ViewController:FUIAuthDelegate{
    func authUI(_ authUI: FUIAuth, didSignInWith authDataResult: AuthDataResult?, error: Error?){
        if error != nil{
            print("Error: \(error)")
            return
        }
        self.userLbl.text = Auth.auth().currentUser?.displayName
    }
}

PODS是：

  # Pods for FBTest
  pod 'Firebase/Core'
  pod 'Firebase/Firestore'
  pod 'FirebaseUI'

pod版本如下：

Using BoringSSL-GRPC (0.0.2)

很好奇Google身份验证的工作方式，但股票标准身份验证已停止工作。

这适用于当前版本5：

override func viewDidLoad() {
        super.viewDidLoad()
        handle = Auth.auth().addStateDidChangeListener({ (auth, user) in
            if user == nil {

                if let authUI = FUIAuth.defaultAuthUI() {
                    authUI.delegate = self

                    let providers: [FUIAuthProvider] = [
                        FUIEmailAuth(),
                    ]
                    authUI.providers = providers

                    let provider = authUI.providers.first as! FUIEmailAuth;
                    provider.signIn(withPresenting: self, email: nil);
                }
            }
            else{
                self.userLbl.text = user?.displayName
            }
        })
    }

此问题已解决。似乎实现方式已更改。

override func viewDidLoad() {
        super.viewDidLoad()
        handle = Auth.auth().addStateDidChangeListener({ (auth, user) in
            if user == nil {

                if let authUI = FUIAuth.defaultAuthUI() {
                    authUI.delegate = self
                    let authViewController = authUI.authViewController()
                    self.present(authViewController, animated: true, completion: {})
                }
            }
            else{
                self.userLbl.text = user?.displayName
            }
        })
    }

并恢复为以前的版本：

pod 'Firebase/Core', '<5'
pod 'Firebase/Firestore', '<5'
pod 'FirebaseUI', '<5'
