I have implemented FirebaseCloudMessaging, getting notifications when the app is in Background but when I install the fresh app willPresent and didReceive Notification delegate not get called after 30 to 35 minute it will start calling.
It happens only when I install the app by removing the old one.
Here is my code, you can check where I did mistake
import UIKit
import Firebase
import UserNotifications
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
// Register for push notification
self.registerForNotification()
FirebaseApp.configure()
Messaging.messaging().delegate = self
return true
}
}
extension AppDelegate: UNUserNotificationCenterDelegate {
//MARK: - Register For RemoteNotification
func registerForNotification() {
UNUserNotificationCenter.current().delegate = self
UNUserNotificationCenter.current().requestAuthorization(options: [.badge, .alert, .sound]) { granted, error in }
UIApplication.shared.registerForRemoteNotifications()
}
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
#if DEVELOPMENT
Messaging.messaging().setAPNSToken(deviceToken, type: .sandbox)
#else
Messaging.messaging().setAPNSToken(deviceToken, type: .prod)
#endif
}
func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {
debugPrint("Unable to register for remote notifications: \(error.localizedDescription)")
}
//MARK: - UNUserNotificationCenterDelegate
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any]) {
debugPrint(userInfo)
}
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
let userInfo = notification.request.content.userInfo
debugPrint(userInfo)
completionHandler([.badge, .alert, .sound])
}
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
let userInfo = response.notification.request.content.userInfo
print(userInfo)
completionHandler()
}
}
extension AppDelegate: MessagingDelegate {
//MARK: - MessagingDelegate
func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String) {
print(fcmToken)
}
func messaging(_ messaging: Messaging, didReceive remoteMessage: MessagingRemoteMessage) {
print(remoteMessage.appData)
}
}
Thanks for help
Replace registerForNotification function code with this one. May be it will help
UNUserNotificationCenter.current().delegate = self
let authOptions: UNAuthorizationOptions = [.alert, .badge, .sound]
UNUserNotificationCenter.current().requestAuthorization(options: authOptions) { (isAllow, error) in
if isAllow {
Messaging.messaging().delegate = self
}
}
UIApplication.shared.registerForRemoteNotifications()
When user allow the notification then this delegate method will be called
func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String) {
print(fcmToken)
}
when notification is tapped
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
//when notification is tapped
}
This method will be called when app is in foreground
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
//this method is called when notification is about to appear in foreground
completionHandler([.alert, .badge, .sound]) // Display notification as
}
