title: UIAlertView with a progressbar
body: <p>I would like to have an UIAlertView showing when I'm uploading my file to the server. But because the files can be huge (up to 500MB) it really needs to have a progress bar. Right now i have a <code>UIActivityIndicatorView</code> to show the app is buisy, but this is not very user friendly in my opinion.</p>
  
  <p>I can't get this to work at all, I would be most gratefull for any help in this matter!</p>
