I am using firebase for push notification. I want to show a notification to the user when the application is in the foreground.

Notifications are working fine when the application is closed. But I want to display a stock iOS notification banner even if the application is active.

I have referred below link:

Displaying a stock iOS notification banner when your app is open and in the foreground?

I want to show notification exactly the same way as shown in above link.

I have already implemented these two methods:

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) {

      completionHandler()
}

Can someone please give me a sample of code for showing push notifications when the application is in the foreground?

  • In foreground, detect the remote notification in didRecieveRemoteNotification and send a local notification – Alwin May 29 '18 at 13:35

  • Your question is not related to Firebase – Anton Belousov May 29 '18 at 14:09
  • @AntonBelousov I don't know why you say that, Firebase swizzle the user Notification Center methods to do their own logic so the answer to this question is 100% dependent on the context that firebase is being used! – simonthumper Feb 11 '20 at 10:17

You can try

@available(iOS 10, *)

    extension AppDelegate : UNUserNotificationCenterDelegate {

    func userNotificationCenter(_ center: UNUserNotificationCenter,
                                willPresent notification: UNNotification,
                                withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {

          completionHandler([.alert, .sound])

    }

}

You can call this function, for push notification:

func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]){
     print("\(userInfo)")
}
