检测（听）音频路由变化在iOS中7 [英] Detect (listen to) audio route change in iOS 7

问题描述

刚开始开发针对iOS 7，发现AudioSession相关的功能和PropertyListeners在iOS的7 pcated德$ P $

Just starting development for iOS 7, and found that AudioSession related functions and PropertyListeners are deprecated in iOS 7.

在我用下面的方法来检测，如果耳机已经被插入或从设备拔出：

Before I use the following method to detect if a headset has been plugged in or unplugged from the device:

    /* add callback for device route change */
    AudioSessionAddPropertyListener (
                                     kAudioSessionProperty_AudioRouteChange,
                                     audioRouteChangeListenerCallback,
                                     (__bridge void *)(self));

然后实现监听器回调做不同的事情，内部的算法。现在的iOS 7日precated它并没有单证上的任何选择，是否有由专家在这里的任何解决方案？谢谢！

Then implement the listener callback to do different things to the internal algorithms. Now iOS 7 deprecated it and there's no documentations on any alternative, Is there any solutions by experts here? Thanks!
