回答1:

Step 1: Include all possible tones in your app's bundle

Step 2: Allow user to select which tone they want

Step 3: Store that on server somewhere

Step 4: When pushing that user, include their desired sound in the package

aps : {
    alert : "Some Message",
    sound : <#userPreferredSound#>
}

You don't have to let your server know what sound the user has selected. The notification JSON payload should contain some custom value like "push_sound" for the sound field. Every time a user selects a sound save the newly selected file into 'Library/Sounds' folder and name it "push_sound". That's it
