swift - 在通知中播放歌曲

我想播放一首歌。收到通知时。当应用程序为前台模式时，我的代码工作正常。我想在应用程序处于后台模式时播放歌曲。请帮忙。

最佳答案

向您的本地通知添加自定义声音

斯威夫特3.0

 func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any]) {
    var state: UIApplicationState = application.applicationState
    if state == .active {
        var soundID: SystemSoundID
        var mainBundle: CFBundleRef = CFBundleGetMainBundle()
        var ref: CFURLRef? = CFBundleCopyResourceURL(mainBundle, ("mySoundName.wav" as? CFString), nil, nil)
        AudioServicesCreateSystemSoundID(ref, soundID)
        AudioServicesPlaySystemSound(soundID)
    }
    else {
        // Push Notification received in the background
    }
}

对于推送通知
将此添加到有效载荷。

{
 aps =
 {
    alert = "message";
    sound = "pushSound.caf";//this file will have to your bundle
   };
}
