如何静音推送通知？

Question

I am using Cordova FCM plugin in order to push notifications either for Android and iOS. I want to allow the customer to mute the notifications - just mute, not block them.

But I can't find out how. I know I can send from first place, from the server, without sound - but in such a case - everyone won't receive sound and this is not the aim. I usually send for topics and from the server I cannot determine who configured his client to mute notifications.

Is this possible to set mute from the client's app? How does WhatsApp handle this (there you can mute notification but not block them totally)?

Answer 1

For iOS, When requesing for user Permmission we pass the array of required values

UNUserNotificationCenter.current() 
.requestAuthorization(options: [.alert, .sound, .badge]) { granted, _ in
  print("Permission granted: \(granted)")
}

From the above, just remove .sound from options array.
