How to programmatically silence the ringer or change the ringer tone on iOS5(如何以编程方式使铃声静音或更改 iOS5 上的铃声)

问题描述

有没有办法在iOS5上降低铃声音量或改变铃声?

Is there a way to reduce the volume of the ringer or change the ringer tone on iOS5?

我检查了 Celestial 框架，但无法实例化 AVSystemController.:-(

I checked out the Celestial framework, but can't instantiate AVSystemController. :-(

我不在乎这个 get 是否是 AppStore 中被拒绝的应用，因为它永远不会被提交.

I don't care if this get's the app rejected in the AppStore as it will never be submitted.

推荐答案

是的.使用 AVSystemController.你不实例化它.这是一个单例.

Yes. Use AVSystemController. You don't instantiate it. It's a singleton.

[[AVSystemController sharedAVSystemController] setVolumeTo:10.0 forCategory:@"Ringtone"];
