Cocos2D 2.1: “Delegate” deprecated in iOS 6. How do I set the delegate for this AVAudioSession?

Question

Started a Cocos2D 2.1 template (with no physics engine) in Xcode 4.5, targeted for iOS 6 and iPad. In the CDAudioManager.m file, the following code...

AVAudioSe

I found a poast about this on the Cocos2D-iPhone.org forums. While I don't fully understand it--but I'm working on it--it did seem to take care of the problem, at least temporarily. What he did was write this method in the CDAudioManger.m file:

-(void) releaseBufferForFile:(NSString *) filePath {
    int bufferId = [self bufferForFile:filePath create:NO];
    if (bufferId != kCDNoBuffer) {
        [soundEngine unloadBuffer:bufferId];
        [loadedBuffers removeObjectForKey:filePath];
        NSNumber *freedBufferId = [[NSNumber alloc] initWithInt:bufferId];
        [freedBufferId autorelease];
        [freedBuffers addObject:freedBufferId];
    }
}
@end

- (void) interruption:(NSNotification*)notification
{
    NSDictionary *interuptionDict = notification.userInfo;
            NSNumber* interuptionTypeValue = [dict valueForKey:AVAudioSessionInterruptionTypeKey];
    NSUInteger interuptionType = [interuptionTypeValue intValue];

    if (interuptionType == AVAudioSessionInterruptionTypeBegan)
        [self beginInterruption];
#if __CC_PLATFORM_IOS >= 40000
    else if (interuptionType == AVAudioSessionInterruptionTypeEnded)
        [self endInterruptionWithFlags:(NSUInteger)[interuptionDict valueForKey:AVAudioSessionInterruptionOptionKey]];
#else
    else if (interuptionType == AVAudioSessionInterruptionTypeEnded)
        [self endInterruption];
#endif
}

Then he replaced:

AVAudioSession *session = [AVAudioSession sharedInstance];
session.delegate = self;

with this:

[AVAudioSession sharedInstance];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(interruption:) name:AVAudioSessionInterruptionNotification object:nil];

If and when I develop a better understand of what this code is doing, I'll be sure to edit this post.
