Hello folks, this is my first question here! I'm developing an app that correctly listen apns notifications, but i couldn't be able to listen for a notification when app is in background or closed and execute a custom code instead notifying the notification UI. I try to use silent notification, but i couldn't find where tell to the os that when a particular notification is received, it have to execute a custom code instead showing the default notification UI. I also tryied to use voip notification, but without success, i 'm not able to execute custom code when app is in foreground or terminated. The final effect could be something like a video call incoming (i.e. skype or whatsapp) and the notification could be the trigger to start the app and play the call ring.
