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:
要播放此声音，您必须在通知负载中指定声音的文件名。例如，假设您在应用程序中添加了一个名为 example.caf 的声音文件，我们可以使用通知负载播放此声音，如下所示：
{
aps =
{
alert = "test example notification message";
sound = "example.caf";
};
}
Then the custom sound will play when your notification arrives.
然后，当您的通知到达时，将播放自定义声音。

Use this method in your app delegte class.
在您的应用委托类中使用此方法。
-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
{
UIApplicationState state = [application applicationState];
if (state == UIApplicationStateActive)
{
NSLog(@"User Info : %@", [userInfo description]);
NSLog(@"User Info Alert Message : %@", [[userInfo objectForKey:@"aps"] objectForKey:@"alert"]);
NSString *messageString = [NSString stringWithFormat:@"%@", [[userInfo objectForKey:@"aps"] objectForKey:@"alert"]];
NSString *playSoundOnAlert = [NSString stringWithFormat:@"%@", [[userInfo objectForKey:@"aps"] objectForKey:@"sound"]];
NSURL *url = [NSURL fileURLWithPath:[NSString stringWithFormat:@"%@/%@",[[NSBundle mainBundle] resourcePath],playSoundOnAlert]];
NSError *error;
audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error];
audioPlayer.numberOfLoops = 0;
[audioPlayer play];
}
}
