connect switches to audio input-software/firmware
<p>We need to connect buttons to the iphone audio jack, so they can control our apps.
I know the apple headphones has 3 buttons,so it can be done somehow.</p>

<p>I couldnt find anyone who did that / any example or something about that, but i know there are so many products that connects to audio jack and control things.</p>

<p>so any hardware explanation / xcode examples would be good .</p>

<p>I think the switches are just a short between 2 points that software can detect.
any help ?</p>

<p>Can i do audio input simulation on xcode via the mac audio jack ??</p>
