iOS FCM 没有收到推送通知

Question

自从我更新到 swift 3，FCM 不起作用。

Push Notifications 在 Capabilities 中启用，证书在 Firebase 控制台上更新。

顺便说一句，android 应用程序上的 fcm 工作正常，它在 ios 上工作，但在更新 swift 3 和新的 firebase 库后，它没有。

AppDelegate.swift：

class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?
    let notificationCenter = NotificationCenter.default

    var connectedToFcm: Bool = false

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

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

        FIRApp.configure()
        NotificationCenter.default.addObserver(self, selector: #selector(self.tokenRefreshNotification), name: NSNotification.Name.firInstanceIDTokenRefresh, object: nil)

        return true
    }

    func applicationDidEnterBackground(_ application: UIApplication) {
        disconnectFromFcm()
    }

    func applicationDidBecomeActive(_ application: UIApplication) {
        connectToFcm()
    }

    func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
        print("REGISTRED")
        FIRInstanceID.instanceID().setAPNSToken(deviceToken, type: .unknown)
    }

    func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError
        error: Error ) {
        print("Registration for remote notification failed with error: \(error.localizedDescription)")
    }

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

    func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any],
                     fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {
        print(userInfo)
    }

    func tokenRefreshNotification(_ notification: Notification) {
        let refreshedToken = FIRInstanceID.instanceID().token()
        if refreshedToken != nil {
            print("InstanceID token: \(refreshedToken!)")
            // Connect to FCM since connection may have failed when attempted before having a token.
            connectToFcm()
        }
    }

    func connectToFcm() {
        guard FIRInstanceID.instanceID().token() != nil else {
            return;
        }
        if connectedToFcm == false {
            FIRMessaging.messaging().disconnect()
            FIRMessaging.messaging().connect { (error) in
                if (error != nil) {
                    self.connectedToFcm = false
                    print("Unable to connect with FCM. \(error)")
                } else {
                    self.connectedToFcm = true
                    print("Connected to FCM.")
                    self.sendTokenToServer()
                }
            }
            return
        }
    }

    func sendTokenToServer() {
        let fcmToken = FIRInstanceID.instanceID().token()
        if self.sharedUser.getToken().characters.count == 0 || fcmToken == nil {
            return
        }
        let params = [
            "reg_id": fcmToken!,
            "dev_id": Config().devId
        ]

        Alamofire.request(Config().fcmUrl, method: .post, parameters: params, encoding: JSONEncoding.default, headers: Config().apiHeaders)
            .validate()
            .responseJSON { response in
                if response.result.isSuccess {
                    print("FCM token send to app server")
                }
            }
    }

    func disconnectFromFcm() {
        FIRMessaging.messaging().disconnect()
        connectedToFcm = false
        print("Disconnected to FCM")
    }
}

Connected to FCM.
FCM token send to app server

我进行了打印以检查应用程序是否获得令牌，并且确实如此。此外，令牌被发送到服务器，我在那里检查它是否正常以及服务器是否正在发送推送。

我在 iOS FCM 集成中遇到了同样的问题，我已经通过在 iOS 10 中使用最新的推送通知代码解决了这个问题。

您需要检查设备的操作系统版本并隔离相关代码。

if #available(iOS 10, *)
        {
            let center = UNUserNotificationCenter.current()
            center.delegate = self
            center.requestAuthorization(options: [.sound, .alert, .badge]) { (granted, error) in
                if error == nil{
                    UIApplication.shared.registerForRemoteNotifications()
                }
            }
        }else
        {
            // Register for remote notifications
            if #available(iOS 8.0, *) {
                // [START register_for_notifications]
                let settings: UIUserNotificationSettings =
                    UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
                application.registerUserNotificationSettings(settings)
                application.registerForRemoteNotifications()
                // [END register_for_notifications]
            } else {
                // Fallback
                let types: UIRemoteNotificationType = [.alert, .badge, .sound]
                application.registerForRemoteNotifications(matching: types)
            }
        }

将此代码放在一个函数中并从完成启动时调用它并注释您的代码。 如果您还有任何问题，请告诉我。

重要：- 导入用户通知

委托：-

func application(_ application: UIApplication, didRegister notificationSettings: UIUserNotificationSettings)
    {

        /**
        Allow device to register for remote notification.
        */
        UIApplication.shared.registerForRemoteNotifications()
        FIRMessaging.messaging().subscribe(toTopic: "/topics/test")
    }



    func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data)
    {
        /**
        Send device token to firebase to get the FCM token for pushnotification from firebase.
        */
        FIRInstanceID.instanceID().setAPNSToken(deviceToken, type: FIRInstanceIDAPNSTokenType.prod)
    }
