检测何时按下音量按钮 [英] Detect when volume button is pressed

问题描述

我已经做了大量研究，我知道Apple不允许这样做，但是没有人有代码，或者有人可以指向我输入代码，该代码使我能够检测到用户何时按下iphone上的提高音量"或降低音量"按钮?

I've done lots of research and I know that Apple will not allow this but does anyone have code or can someone point me to code that enables me to detect when a user presses either the up or down volume button on the iphone?

我需要能够检测到哪一个被按下(向上或向下).我不会向具有此代码的苹果提交任何东西.我只是想知道是否可能?

I need to be able to detect which one is pressed (up or down). I will not be submitting anything to apple that has this code. I am just wondering if possible?

谢谢.
