【问题描述】：

。我尝试更改代码的许多方面均无济于事。我还尝试在模拟器和手机上运行该应用程序，但通知都没有出现。我正在关注 Firebase 文档，但它仍然无法正常工作。这是我的 AppDelegate 文件：

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate 

    var window: UIWindow?
    let gcmMessageIDKey = "gcm.message_id"


    func applicationDidBecomeActive(_ application: UIApplication) 
    

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool 
        // Override point for customization after application launch.
           SDKApplicationDelegate.shared.application(application, didFinishLaunchingWithOptions: launchOptions)


        if #available(ios 10.0, *) 
          // For iOS 10 display notification (sent via APNS)
          UNUserNotificationCenter.current().delegate = self

          let authOptions: UNAuthorizationOptions = [.alert, .badge, .sound]
          UNUserNotificationCenter.current().requestAuthorization(
            options: authOptions,
            completionHandler: _, _ in )

            Messaging.messaging().delegate = self

         else 
          let settings: UIUserNotificationSettings =
          UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
          application.registerUserNotificationSettings(settings)
        



        application.registerForRemoteNotifications()

        FirebaseApp.configure()



        return true
    

    func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any]) 
      // If you are receiving a notification message while your app is in the background,
      // this callback will not be fired till the user taps on the notification launching the application.
      // TODO: Handle data of notification

      // With swizzling disabled you must let Messaging know about the message, for Analytics
      // Messaging.messaging().appDidReceiveMessage(userInfo)

      // Print message ID.
      if let messageID = userInfo[gcmMessageIDKey] 
        print("Message ID: \(messageID)")
      

      // Print full message.
      print(userInfo)
    

    func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any],
                     fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) 
      // If you are receiving a notification message while your app is in the background,
      // this callback will not be fired till the user taps on the notification launching the application.
      // TODO: Handle data of notification

      // With swizzling disabled you must let Messaging know about the message, for Analytics
      // Messaging.messaging().appDidReceiveMessage(userInfo)

      // Print message ID.
      if let messageID = userInfo[gcmMessageIDKey] 
        print("Message ID: \(messageID)")
      

      // Print full message.
      print(userInfo)

      completionHandler(UIBackgroundFetchResult.newData)
    




@available(iOS 10, *)
extension AppDelegate : UNUserNotificationCenterDelegate 

  // Receive displayed notifications for iOS 10 devices.
  func userNotificationCenter(_ center: UNUserNotificationCenter,
                              willPresent notification: UNNotification,
    withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) 
    let userInfo = notification.request.content.userInfo

    // With swizzling disabled you must let Messaging know about the message, for Analytics
    // Messaging.messaging().appDidReceiveMessage(userInfo)

    // Print message ID.
    if let messageID = userInfo[gcmMessageIDKey] 
      print("Message ID: \(messageID)")
    

    // Print full message.
    print(userInfo)

    // Change this to your preferred presentation option
    completionHandler([])
  

  func userNotificationCenter(_ center: UNUserNotificationCenter,
                              didReceive response: UNNotificationResponse,
                              withCompletionHandler completionHandler: @escaping () -> Void) 
    let userInfo = response.notification.request.content.userInfo
    // Print message ID.
    if let messageID = userInfo[gcmMessageIDKey] 
      print("Message ID: \(messageID)")
    

    // Print full message.
    print(userInfo)

    completionHandler()
  


extension AppDelegate:MessagingDelegate 

 func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String) 
      print("Firebase registration token: \(fcmToken)")

      let dataDict:[String: String] = ["token": fcmToken]
      NotificationCenter.default.post(name: Notification.Name("FCMToken"), object: nil, userInfo: dataDict)
      // TODO: If necessary send token to application server.
      // Note: This callback is fired at each app startup and whenever a new token is generated.
    

    func messaging(_ messaging: Messaging, didReceive remoteMessage: MessagingRemoteMessage) 
        print("Message Data:  ", remoteMessage.appData)
    

【问题讨论】：

您是否遵循了firebase文档以及iOS证书的配置？

第一件事。您将不会在模拟器中收到通知，始终使用实际设备进行测试。你是从谷歌控制台发送通知吗？

@Faysal Ahmed，是的，我正在关注 firebase 文档并配置了 iOS 证书。 Krunal Nagvadia 是的，我正在实际设备上进行测试，并从我的 Firebase 控制台发送通知！

检查您的 plist、捆绑和配置证书是否与您的项目匹配。如果仍然无法正常工作，请在您的控制台中创建新项目并逐步重复到达过程。我有时会看到谷歌在使用 iOS 应用程序进行配置时遇到问题。还要添加正确的GoogleService-Info.plist 并允许在您的设备中通知

【参考方案1】：

处理推送通知：-

我正在发布这个解决方案，因为它对我有用。但在使用它之前，请检查您是否已在控制台上的 iOS 应用配置下上传了正确的 APNs 身份验证密钥。 - 转到您的 AppDelegate 文件。 - 第 1 步：在此函数中编写此代码：

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate 

    var window: UIWindow?
    var application : UIApplication?

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

        ApplicationDelegate.shared.application(application, didFinishLaunchingWithOptions: launchOptions)

        FirebaseApp.configure()

        if #available(iOS 10.0, *) 
            // For iOS 10 display notification (sent via APNS)
            UNUserNotificationCenter.current().delegate = self

            Messaging.messaging().delegate = self

            let authOptions: UNAuthorizationOptions = [.alert, .badge, .sound]
            UNUserNotificationCenter.current().requestAuthorization(
                options: authOptions,
                completionHandler: _, _ in )
         else 
            let settings: UIUserNotificationSettings =
                UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
            application.registerUserNotificationSettings(settings)
        

        application.registerForRemoteNotifications()

        return true
    

    

    func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) 
        _ = (deviceToken as NSData).bytes.bindMemory(to: CChar.self, capacity: deviceToken.count)
        var token = ""
        token = /Messaging.messaging().fcmToken
        print("FCM token: \(token )")
        Messaging.messaging().apnsToken = deviceToken
    

    func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) 
        print("Did Fail to Register for Remote Notifications")
        print("\(error), \(error.localizedDescription)")
    

    func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any]) 

        print("didReceiveRemoteNotification \(userInfo)")
    


@available(iOS 10, *)
extension AppDelegate : UNUserNotificationCenterDelegate 

    // Receive displayed notifications for iOS 10 devices.
    func userNotificationCenter(_ center: UNUserNotificationCenter,
                                willPresent notification: UNNotification,
                                withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) 

        let userInfo = notification.request.content.userInfo

        print("======== messafe received %@", userInfo)

       //handle push notification

        completionHandler([.alert, .badge, .sound])
    

    @available(iOS 10, *)
    func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) 

        switch UIApplication.shared.applicationState 
        case .active:

            break
        case .background, .inactive :

            let userInfo = response.notification.request.content.userInfo

           //handle push notification
            break

        default:

            break
        
        completionHandler()
    

    func performNotificationAction(userInfo : [AnyHashable : Any], completion : (UNNotificationPresentationOptions) -> ()) 


        if UIApplication.shared.applicationState == .active || UIApplication.shared.applicationState == .background 

        

        else if UIApplication.shared.applicationState == .inactive 

        
    

    func pushNavigation(userInfo : [AnyHashable : Any], completion : (UNNotificationPresentationOptions) -> ()) 


    

extension AppDelegate : MessagingDelegate 

    public func messaging(_ messaging: Messaging, didReceive remoteMessage: MessagingRemoteMessage) 


    

    public func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String) 

        print(fcmToken)
    

【讨论】：

它说“使用未解析的标识符'ApplicationDelegate'

你可以使用 SDKApplicationDelegate.shared.application(application, didFinishLaunchingWithOptions: launchOptions)

错误消失了，但问题依然存在。我会检查并通知您！
