swift - “自动登录”不再起作用

Question

我的应用使用了 Firebase 项目，用户必须在该项目上创建帐户才能访问应用的内容。

为了避免用户每次启动应用程序时都必须登录，我将(在 AppDelegate 中):

if Auth.auth().currentUser != nil {
        self.window = UIWindow(frame: UIScreen.main.bounds)
        let storyboard = UIStoryboard(name: "Main", bundle: nil)
        let viewController = storyboard.instantiateViewController(withIdentifier: "tabBar")
        self.window?.rootViewController = viewController
        self.window?.makeKeyAndVisible()
    } else {
        self.window = UIWindow(frame: UIScreen.main.bounds)
        let storyboard = UIStoryboard(name: "Main", bundle: nil)
        let viewController = storyboard.instantiateViewController(withIdentifier: "InscriptionViewController")
        self.window?.rootViewController = viewController
        self.window?.makeKeyAndVisible()
    }

这段代码在过去几个月确实有效，但现在不行了(我所有的 pod 都是最新的)

为什么它不再工作了？

您的 AppDelegate 应该如下所示。

import UIKit
import Firebase

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

  var window: UIWindow?

  func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {

  FirebaseApp.configure()

  if Auth.auth().currentUser != nil {
  //your code 
  }

  }
}
