How can I get the content (raw/sample data) of an iPod-track? I've seen apps like "Ringtone Designer" and iMovie which can do it, but I have no idea which api they use or what they do. I could imagine that iMovie uses private apis, but "Ringtone Designer" is a third-party app, so it must be possible with the public api-functions. ...
I've added my database populate code to the thread method. However, sometimes they may not be any data to show in the graph.

Having failed in trying to puzzle together different sources to any form of coherent approach or concept I turn, once again to the learned people of StackOverflow. My problem is quite specific and maybe that's why I'm having trouble finding information that fits or maybe I just suck at searching. Either way, here goes. I am building an ...

The problem is, that its retain count never goes to ...
