Question

我是Firebase云消息的新手，下面是我使用的相关代码。当我尝试从Firebase通知编辑器发送推送通知时，尽管邮件状态已完成。我的客户端没有收到任何消息。我错过了什么吗？我的用例需要，将消息从一个应用程序发送到另一个具有不同软件包ID的应用程序你会推荐什么应用服务器？

class AppDelegate: UIResponder, UIApplicationDelegate {

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {Messaging.messaging().delegate = self
        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 })
        } else {
            let settings: UIUserNotificationSettings = UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
            application.registerUserNotificationSettings(settings)
        }

        application.registerForRemoteNotifications()
        FirebaseApp.configure()
    }

     // [START receive_message]
     func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any]) {
         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],

        if let messageID = userInfo[gcmMessageIDKey] {
            print("Message ID: \(messageID)")
        }

        // Print full message.
        print(userInfo)

        completionHandler(UIBackgroundFetchResult.newData)
    }
    // [END receive_message]

    func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {
        print("Unable to register for remote notifications: \(error.localizedDescription)")
    }


    func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
        print("APNs token retrieved: \(deviceToken)")

        // With swizzling disabled you must set the APNs token here.
        Messaging.messaging().apnsToken = deviceToken
}

    // [START ios_10_message_handling]
    @available(iOS 10, *)
extension AppDelegate : UNUserNotificationCenterDelegate {

    // Receive displayed notifications for iOS 10 devices.
    func userNotificationCenter(_ center: UNUserNotificationCenter,
                            willPresent notification: UNNotification,

        // TODO: If necessary send token to application server.
        // Note: This callback is fired at each app startup and whenever a new token is generated.
    }

您需要设置Firebase Messaging委托

Messaging.messaging().delegate = self

iOS-FCM没有收到PUSH通知
