title: Unzipping the file in my iphone app
body: <p>i am trying to unzip a file in my iphone app, i searched it on google and found this <a href="http://github.com/tastefulworks/twziparchive" rel="nofollow">http://github.com/tastefulworks/twziparchive</a> but it says to add libz library into your project but i am not able to find this library.
  Can anybody have any idea about this or any other helpful link to perform unzipping.</p>
