run music in background running application in xcode

Kindly send me a code sample of how to run the music file when the application goes in the background. [iphone 4.1].

I don't want the music to stop when my application goes in the background just like the itunes music.

Best Regards,

Add "audio" to UIBackgroundModes in your PLIST.

For playback to continue when the phone locks;

#import <AVFoundation/AVFoundation.h>
#import <AudioToolbox/AudioToolbox.h>

AVAudioSession *audioSession = [AVAudioSession sharedInstance];

NSError *setCategoryError = nil;
[audioSession setCategory:AVAudioSessionCategoryPlayback error:&setCategoryError];
if (setCategoryError) { /* handle the error condition */ }

NSError *activationError = nil;
[audioSession setActive:YES error:&activationError];
if (activationError) { /* handle the error condition */ }

You can see the sample in the book of Erica Sadun - how to play audio file ...
