如何确定外接耳机是否连接到iPhone？ [英] How to find out if an external headset is connected to an iPhone?

问题描述

是否可以检测到用户的外接耳机已插入iPhone的3.5毫米接口或30针接头？我想只将音频输出到外部音频设备，如果没有连接则保持静音。

Is it possible to detect that the user has an external headset plugged into the iPhone's 3.5mm connector or the 30-pin connector? I want to output audio only to an external audio device, and keep silent if nothing is connected.

推荐答案

答案非常相似回答这个问题，但是你想得到 kAudioSessionProperty_AudioRoute 属性而不是。

The answer is very similar to the answer to this question, but you'll want to get the kAudioSessionProperty_AudioRoute property instead.
