title: Convert NSData to Zip File then Unzip Zip File
body: <p>I have a JSON object that contains some <code>NSData</code>. The <code>NSData</code> is a zip file that I have to unzip and store and utilize the files locally in my app.</p>
  
  <p>I think I can use something like <a href="https://github.com/ZipArchive/ZipArchive" rel="nofollow noreferrer">ZipArchive</a> for the unzipping, but I'm not sure how to convert the <code>NSData</code> to a file that I can unzip.</p>
  
  <p>Does anyone know how to handle this sort of issue?</p>
