title: LZMA SDK iOS to show progress
body: <p>If anyone has used the iOS wrapper for the LZMA SDK available at <a href="https://github.com/mdejong/lzmaSDK" rel="nofollow">https://github.com/mdejong/lzmaSDK</a> and have been able to tweak it in order to see the progress of unarchiving, please help. </p>
  
  <p>I am going to use this SDK in iOS to extract a 16MB file, which uncompresses to a 150MB file, and this takes around 40seconds to complete. It would be good to have some kind of callback for showing the progress of uncompression. </p>
  
  <p>Help is greatly appreciated. 
  Thanks</p>
