title: How do I download a youtube video in iOS
body: <p>I know how to launch a youtube video within an iOS web view, but how can I download that video to save on my iPad app? Is it possible? Do I need to use some call with a NSURLConnection object and then save the received data into the proper file format?</p>
  
  <p>One specific point I am unsure about is what the url to request the file would be. When viewing a video on youtube, the downloadable videos are triggered with a button, so it's not evident to me what the url would be.</p>
