UISlider for scrubbing the AQPlayer like iPod

Can somebody tell me how to scrub the AQPlayer ( used in Apple's SpeakHere example ) using a UISlider like the iPod does?

I know how to handle the slider part, but once I have my value from the slider, what do I need to set/change/update in AQPlayer, or the A开发者_如何学PythonudioQueue, so that the player moves to that part of the Queue and continues playing from that point? Is there any easy way to do this with a percentage of the playing time or do I have to make some calculations with the packets??

Thanks for any input.

For anyone who also needs to seek/scrubb in an audio file, I found a solution to my question at the following link: Audio Queues

Have a look at the function

-(void)seek:(UInt64)packetOffset;

It worked perfectly after some initial fine tuning.
