Detecting mp3 BPM by using Objective-C

Detecting mp3 BPM by using Objective-C

I'm working on an iOS Project. I'm try to detect the BPM of mp3 file. But
I've search on google for the answer. I only found a framework called
Soundtouch. But it only can work on WAV file. Is there any other framework
or code can tell the BPM of mp3 file? Thanks for your help.
