title: Fully featured file download manager for iOS
body: <p>I've been looking for a nice file download manager I can use in my app and haven't been able to find anything with the features I want...</p>
  
  <ul>
  <li>queue multiple async downloads</li>
  <li>control number of simultaneous downloads</li>
  <li>block based callbacks include success, fail and progress percentage updates</li>
  <li>cancel and pause/resume</li>
  <li>resume interrupted downloads (e.g. when the app is force closed)</li>
  </ul>
  
  <p>the following would be nice bonuses</p>
  
  <ul>
  <li>remaining time estimation</li>
  <li>ability to change order in queue</li>
  <li>handling of long term storage/deletion</li>
  </ul>
  
  <p>Does anyone know of anything like this? If there's nothing out there I guess I can roll my own and open source it.</p>
  
  <p>Thanks!</p>
