有没有办法以编程方式使OSX上的声音静音?
问题描述：
是否可以通过编程方式使OSX上的声音静音而不使用私有API并以Mac App Store接受的方式.
Is there a way to programmatically mute the sound on OSX without using private APIs and in a way that is accepted by the Mac App Store.
答
对于MAC OS X: 本教程可能会有所帮助.
对于IOS:否
静音"是系统范围的设置.因此，对于使用官方SDK开发的应用程序，不能更改(在大多数情况下甚至不能访问)系统范围的设置.
Sound Mute is a system-wide setting. So for applications developed using the official SDK cannot change (and in most cases cannot even access) system-wide settings.
从技术上讲，可以通过Celestial.framework中的私有AVSystemController类更改系统容量，但会阻止您的应用获得Apple的批准.
It is technically possible to change the system volume through the private AVSystemController class in Celestial.framework, but will prevent your app from getting Apple's approval.
