How to record audio as mp3 file by using AvAudiorecorder in iOS

How to record audio as an mp3 file by using AvAudiorecorder? I am using the following code for the recorder setting

recordSetting =  [NSDictionary dictionaryWithObjectsAndKeys:
                  [NSNumber numberWithInt:AVAudioQualityMin],AVEncoderAudioQualityKey,
                  [NSNumber numberWithInt:16], 
                   AVEncoderBitRateKey,
                   [NSNumber numberWithInt: 2], 
                   AVNumberOfChannelsKey,
                   [NSNumber numberWithFloat:44100.0], 
                   AVSampleRateKey, nil];

Whilst you can play MP3 files using AVAudioPlayer, you can't record in MP3 format with AVAudioRecorder (see this SO post and this SO post). If you need a compressed format, but it doesn't have to be MP3, I suggest recording in AAC format.

Add

[NSNumber numberWithInt:kAudioFormatMPEGLayer3] forKey:AVFormatIDKey

However it's impossible to encode mp3 format at IPhone because of royalty.
