Question

I’ve got some problems IN MY APP, some people don’t hear sound. I’m using mp3 files and the Audiotoolbox library.

Can someone if I should use the avfoundation or whether the audiotoolbox library is better ?

Answer 1

Try playing MP3 file as below:

NSURL *url = [NSURL fileURLWithPath:[NSString stringWithFormat:@"%@/audiofile.mp3", [[NSBundle mainBundle] resourcePath]]];

NSError *error;
audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error];
audioPlayer.numberOfLoops = -1;

if (audioPlayer == nil)
    NSLog([error description]);             
else 
    [audioPlayer play];

AudioToolbox is specifically for SystemSound and AVAudioPlayer of AVFoundation is for sounds included in our app..
