问题描述

是否可以通过编程方式更改设备音量?也许使用音频会话?

Is there a way to change the device volume programmatically? maybe using audio session?

推荐答案

我非常确定不可能控制实际设备的音量(因为这也有些麻烦)控制正在播放的某些媒体是另一回事.但是，您可以查看MPVolumeView: https://developer.apple.com/library/ios/documentation/MediaPlayer/Reference/MPVolumeView_Class/index.html 用于显示用于设置音量的视图.

I'm pretty sure that it is not possible to control the actual device volume (as this would also be a bit obtrusive) Controlling some media you're playing is another thing. You could however look into MPVolumeView: https://developer.apple.com/library/ios/documentation/MediaPlayer/Reference/MPVolumeView_Class/index.html for displaying a view for setting the volume.
