Question

I am creating an audio player application, i need to enable the user to fast forward and backward a song by holding a button(seperately for each). I’ve done for playing, stopping, skip to next and previous song. But i got stuck with this section. I dont know the method to implement this. pls help.

Answer 1

Use the currentTime and duration properties.

i.e. to skip forward

NSTimeInterval time = avPlayer.currentTime;
time += 5.0; // forward 5 secs
if (time > avPLayer.duration)
{
    // stop, track skip or whatever you want
}
else
    avPLayer.currentTime = time;

Similar for going backwards, only compare currentTime against 0, instead of duration
