配置收到推送通知时播放的声音

Question

How can we configure the sound which gets played when an application is in the background and a push notification is received?

Answer 1

Check out the "The Notification Payload" section of this document .

Example JSON Payload (adapted from above document):

{
    "aps" : {
        "alert" : "You got your emails.",
        "badge" : 9,
        "sound" : "bingbong.aiff"
    }
}

The key you're looking for here is sound , it's a string that points to an aiff , caf , or wav file within your bundle.
