iPhone MPMusicPlayerController playback starting position
<p>I'm using Media Player Framework to access the user's music library on iPhone. I would like to set the playback starting position so that I can start playing a song from 30 second mark, for example. </p>

<p>I have trouble finding out how to do this. The MPMediaPlayerController only offers <code>beginSeekingForward</code> but that's not quite what I'm looking for as it simply accelerates the playback speed. </p>

<p>There is probably something really simple that I'm missing. </p>
