AVAudioPlayer rate

Question

So I\'m trying to play a sound file at a different rate in iOS 5.1.1, and am having absolutely no luck. So far I have tried setting the rate of the AVAudioPlayer:

Answer 1

Modify the code to:

avPlayer = [[AVPlayer alloc] initWithURL:referenceURL];

[avPlayer play]; //call play first

avPlayer.rate = 0.5; //then set rate
