Tengo actualmente una aplicación de chat tanto en android (java) como en iOS (swift) y ambos funcionan con la misma base de datos en Firebase. necesito ayuda para configurar las notificaciones push en segundo plano ya que lo intentado y nada.Si envio un mensaje con un usuario de Android a un usuario de iOS no llegan las notificaciones cuando la aplicación está en segundo plano, pero de Android a Android, de ios a ios y de ios a Android si llegan.De android a ios solo confirma si el usuario ios está dentro de la aplicación, pero necesito que lleguen las notificaciones ios cuando la aplicación está cerrada o en segundo plano.en iOS ya tengo configurados los certificados necesarios de apple y el proyecto firebasenecesito de su apoyo.Adjunto el codigo fuente:AppDelegate.swift@UIApplicationMain class AppDelegate: UIResponder, UIApplicationDelegate { let gcmMessageIDKey = "gcm.message_id" var window: UIWindow? func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool { // Override point for customization after application launch. FirebaseApp.configure() // [START set_messaging_delegate] Messaging.messaging().delegate = self // [END set_messaging_delegate] // Register for remote notifications. This shows a permission dialog on first run, to // show the dialog at a more appropriate time move this registration accordingly. // [START register_for_notifications] 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() // [END register_for_notifications] //let pushManager = PushNotificationManager(userID: Auth.auth().currentUser!.uid) //pushManager.registerForPushNotifications() GMSPlacesClient.provideAPIKey("AIzaSyAUapKf62FHGkHVbpc6HY8R7qncJ83-R10") GMSServices.provideAPIKey("AIzaSyAUapKf62FHGkHVbpc6HY8R7qncJ83-R10") IQKeyboardManager.shared.enable = true GADMobileAds.sharedInstance().start(completionHandler: nil) 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) } func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) { print("Unable to register for remote notifications: \(error.localizedDescription)") } // This function is added here only for debugging purposes, and can be removed if swizzling is enabled. // If swizzling is disabled then this function must be implemented so that the APNs token can be paired to // the FCM registration token. 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 } }@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([.alert, .badge, .sound]) } 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] let ref = Database.database().reference() let uid = Auth.auth().currentUser?.uid ?? "" if uid != "" { ref.child("Tokens").child(uid).updateChildValues(dataDict) } NotificationCenter.default.post(name: Notification.Name("FCMToken"), object: nil, userInfo: dataDict) } Messaging.messaging().shouldEstablishDirectChannel to true. func messaging(_ messaging: Messaging, didReceive remoteMessage: MessagingRemoteMessage) { print("Received data message: \(remoteMessage.appData)") }}La función que uso para enviar la notificación:func sendPushNotification(payloadDict: [String: Any]) { let url = URL(string: "https://fcm.googleapis.com/fcm/send")! var request = URLRequest(url: url) request.setValue("application/json", forHTTPHeaderField: "Content-Type") // get your **server key** from your Firebase project console under **Cloud Messaging** tab request.setValue("key= aqui va mi server key", forHTTPHeaderField: "Authorization") request.httpMethod = "POST" request.httpBody = try? JSONSerialization.data(withJSONObject: payloadDict, options: []) let task = URLSession.shared.dataTask(with: request) { data, response, error in guard let data = data, error == nil else { print(error ?? "") return } if let httpStatus = response as? HTTPURLResponse, httpStatus.statusCode != 200 { print("statusCode should be 200, but is \(httpStatus.statusCode)") print(response ?? "") } print("Notification sent successfully.") let responseString = String(data: data, encoding: .utf8) print(responseString ?? "") } task.resume() }y asi es como llamo esa funcion:let notifPayload: [String: Any] = ["to": self.token!, "notification": ["title": self.usernamelbl.text!,"body": self.msgtf.text! ,"badge":1,"sound":"default"]] self.sendPushNotification(payloadDict: notifPayload)Saludos.-
