想在锁屏后台播放报警提示音。
添加了UIBackgroundModes，audio，官方审核不通过！
IOS的闹钟是怎么实现的，锁屏不能播放声音？原来是用了notification方法。

notification.soundName= UILocalNotificationDefaultSoundName;//声音，可以换成alarm.soundName = @"myMusic.caf"
- 2.16 - Multitasking Apps may only use background services for their intended purposes: VoIP, audio playback, location, task completion, local notifications, etc.
2.16 Details
Your
app declares support for audio in the UIBackgroundModes key in your
Info.plist but did not include features that require persistent audio.
Specifically,
playing an alert or act as an alarm for the hardware is not appropriate
for the app to use background audio functionality.
Next Steps
The
audio key is intended for use by applications that provide audible
content to the user while in the background, such as music player or
streaming audio applications.
Please revise your app to provide
audible content to the user while the app is in the background or remove
the "audio" setting from the UIBackgroundModes key.
