How to play custom sound file when user get push notification? [duplicate]

Answer 1

To play this sound you must specify the filename of the sound in the notification payload. For example, lets say you've added a sound file named example.caf into your application, we can play this sound with the notification payload as below:

{
    aps =     
    {
        alert = "test example notification message";
        sound = "example.caf";
    };
}

Then the custom sound will play when your notification arrives.
