title: Is it possible to download a .zip file into iPhone when user clicks a link inside UIWebView?
body: <p>In a new app, I plan to let users download their own files and stored them inside iPhone. The process is typically:</p>
  
  <ul>
  <li>iPhone present a web page by UIWebView, in which there are several links to .zip files </li>
  <li>the user browser the page and click on one of the .zip file link</li>
  <li>iPhone downloads the file into the iPhone document folder, closes WebView, acknowledges the user when download is complete</li>
  </ul>
  
  <p>How can that be done? Thanks</p>
