Don't show notification when in foreground

Question

I\'m sending push notification from my node server using the Firebase admin SDK. But on iOS I only want to show the notification when the app is in the background/terminated

Answer 1

You can achieve this in AppDelegate by using the applicationState,

In iOS8:

  func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any]) {

    if !UIApplication.shared.applicationState == .active {
     // Handle your push notification here   
    }

}

In iOS10:

1. import UserNotifications framework

2. Implement UNUserNotificationCenterDelegate method

   func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
   
   
   if UIApplication.shared.applicationState == .active { // In iOS 10 if app is in foreground do nothing.
       completionHandler([])
   } else { // If app is not active you can show banner, sound and badge.
       completionHandler([.alert, .badge, .sound])
   }
   
   }
   

Thanks.
