hi i had included the following code to receive push notification from FCM server InstanceId is available and the FCM console shows Completed push notification but no function is being called in the app delegate. please help what i am missing
func registerForPushNotifications(_ application: UIApplication) {
if #available(iOS 10.0, *) {
Messaging.messaging().delegate = self
let center = UNUserNotificationCenter.current()
center.delegate = self
center.requestAuthorization(options: [.badge, .sound, .alert], completionHandler: {(grant, error) in
if error == nil {
if grant {
application.registerForRemoteNotifications()
} else {
//User didn't grant permission
}
} else {
print("error: ",error?.localizedDescription)
}
})
} else {
let notificationSettings = UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
application.registerUserNotificationSettings(notificationSettings)
}
application.registerForRemoteNotifications()
NotificationCenter.default.addObserver(self,
selector: #selector(self.tokenRefreshNotification),
name: .InstanceIDTokenRefresh,
object: nil)
}
func application(_ application: UIApplication, didRegister notificationSettings: UIUserNotificationSettings) {
if notificationSettings.types != UIUserNotificationType() {
application.registerForRemoteNotifications()
self.isNotificationEnabled { (isEnabled) in
if isEnabled{
print("Push notification enabled")
}else{
print("Push notification not enabled")
}
}
}
}
func isNotificationEnabled(completion:@escaping (_ enabled:Bool)->()){
if #available(iOS 10.0, *) {
UNUserNotificationCenter.current().getNotificationSettings(completionHandler: { (settings: UNNotificationSettings) in
let status = (settings.authorizationStatus == .authorized)
completion(status)
})
} else {
if let status = UIApplication.shared.currentUserNotificationSettings?.types{
let status = status.rawValue != UIUserNotificationType(rawValue: 0).rawValue
completion(status)
}else{
completion(false)
}
}
}
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
var token = ""
for i in 0..<deviceToken.count {
token = token + String(format: "%02.2hhx", arguments: [deviceToken[i]])
}
Messaging.messaging()
.setAPNSToken(deviceToken, type: MessagingAPNSTokenType.unknown)
}
func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {
print("Registration failed!",error.localizedDescription)
}
func tokenRefreshNotification(_ notification: Notification) {
if let refreshedToken = InstanceID.instanceID().token() {
print("InstanceID token: \(refreshedToken)")
}
connectToFcm()
}
func connectToFcm() {
Messaging.messaging().shouldEstablishDirectChannel = true
}
Extensions for app delegate
@available(iOS 10, *)
extension AppDelegate : UNUserNotificationCenterDelegate {
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
completionHandler(.alert)
}
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
let userInfo = response.notification.request.content.userInfo as NSDictionary
print("userinfo",userInfo)
}
}
extension AppDelegate : MessagingDelegate {
// [START refresh_token]
func messaging(_ messaging: Messaging, didRefreshRegistrationToken fcmToken: String) {
print("Firebase registration token: \(fcmToken)")
}
func messaging(_ messaging: Messaging, didReceive remoteMessage: MessagingRemoteMessage) {
print("Received data message: \(remoteMessage.appData)")
}
}
By this above code i get instanceID generated and i have also uploaded the .p8 file with app prefix and key. when i send a push notification its status becomes completed but no function is being called in the app delegate
