推荐答案

如果你想让你的应用程序在应用程序商店中，那么就没有苹果批准实际上将整个iPhone静音的方法。某些库但它们未被批准。

If you want your app to be in app store , then there is no apple approved method to actually mute whole iPhone.There are certain libraries but they are not approved.

Apple关于音频会话的文档

根据文档你只能要求用户让手机静音，你可以响应某些音频变化，如其他声音，电话，电子邮件声音，但你不能以编程方式静音。

According to the documentation you can only ask the user to have the phone silenced physically and you can respond to certain audio changes such as other sounds,phone calls, email sounds but you cannot mute programmatically.

另请参阅此有关iPhone编程的文档请参阅3.3部分了解音频。（可在iOS中访问和执行的事件）。

Also See this Documentation on Programming in iPhone See the part 3.3 for Audio.(Events that can be accessed and performed in iOS).
