iOS FCM没有收到推送通知 [英] iOS FCM not getting push notifications

问题描述

自从我更新到Swift 3之后，FCM无法正常工作.

Since i updated to swift 3, FCM doesn't work.

Push Notifications，并且在Firebase控制台上更新了证书.

Push Notifications are enabled in Capabilities and Certificates are updated on Firebase console.

顺便说一句，Android应用程序上的fcm可以正常工作，并且可以在ios上运行，但是在swift 3和新的firebase库上更新后，它就不能正常运行.

Btw, fcm on android app works just fine, and it was working on ios but after update on swift 3 and new firebase libraries, it doesn't.

AppDelegate.swift:

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 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 {

                    self.connectedToFcm = false
                    print("Unable to connect with FCM. \(error)")
                } else {

                    print("Connected to FCM.")
                    self.sendTokenToServer()
                }
            }
            return

    }

    func sendTokenToServer() {

        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")
                }
            }
    }

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，并且确实获得了令牌.另外，令牌也被发送到服务器，我检查了服务器是否正常以及服务器是否正在发送推送.

I made prints to check if app gets token, and it does. Also, token is sent to server and i checked there if it is ok and if server is sending push.

推荐答案

iOS FCM集成也遇到了相同的问题，我已经通过在iOS 10中使用最新的推送通知代码解决了该问题.

I have faced same issue with iOS FCM integration I have solved it by using latest code for push notification in iOS 10.

您需要检查设备的操作系统版本并隔离相关代码.

You need to check the OS version of the device and segregate relevant codes.

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)
            }
        }

将此代码放入函数中，并在启动完成后调用它，并注释您的代码. 如果您还有任何问题，请告诉我.

Put this code in a function and call it from did finish launching also comment your code. Do let me know if you still have any issues.

重要:-导入用户通知

代理:-

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)
    }
