I'm trying to make notification ringing when app is not running in IOS.
Here is my code.
this.notificationListener = firebase.notifications().onNotification((notification: Notification) => {
// SET SYSTEM DEFAULT SOUND!
notification.setSound("default");
firebase.notifications().displayNotification(notification);
});
When app is in background or foreground ( Maybe I can say 'app is running'), notification rings well.
Should I need to use other listener? Or should I need to add my own sound file for ringing?
