Sound Position Indicator

I’m developing a Soundfile-Player for a friend of mine and i have to show a slider which indicates the position of the soundfile.
In addition i want to move the actual position with the slider.
After a boring hour of searching the forum i wanna ask if anybody has already solved that problem.

Any help is urgently welcome.

What are you using to play the sound file?

In my prototype i’m using simple iOSSound to play the sound.

Problem solved with iOSKit and AVAudioPlayer.
