Fast Rewind & Fast Forward in AVAudioPlayer

Question

I am implementing AVAudioPlayer and fast-rewind,fast-forward functionality. I have made two button with gesture, images and glow effects. Currently when I tab on fast-forward, it initially forward the playing item to 10 sec and then playing same way as in normal, even though I am still pressing the button. I want to implement it exactly same like in Iphone/Ipod standard app.

Answer 1

One possible solution is to implement the repeating action by an NSTimer . Have a look at UIButton Touch and Hold .

Answer 2

You can use an AVPlayer instead and change the rate property on touch down. Change it to -2 for rewind and 2 for fast-forward. And remember to change the rate back to 1 on touch up inside/outside.

EDIT AVPlayer 's rate property supports values outside the 0.0 - 1.0 range IF

the associated player item returns YES for the AVPlayerItem properties canPlaySlowForward or canPlayFastForward
