First link I posted mentions "mp3" almost a dozen times...

#import <AVFoundation/AVFoundation.h> 

NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"foo" ofType:@"mp3"]]; 
audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:nil];
[audioPlayer play];

I think it is against the rules to develop a competing Apple application.

How it is against the rules to develop a competing Apple application?

How it is against the rules to develop a competing Apple application?

Read the SDK agreement. There are rules somewhere around section 3.3.

Not every app that plays mp3's is a competing app. Most games with built-in mp3 background music for instance.

Hi all!
You can add this code in .mm file bellow:

if (audioFormat.mBytesPerPacket == 0 || audioFormat.mFramesPerPacket == 0) {
packetDescriptions = (AudioStreamPacketDescription*)malloc(
numPacketsToRead * sizeof(AudioStreamPacketDescription)
);
} else {
packetDescriptions = NULL;
}

I have try and very good,
