title: How can you get custom iOS document type icons to show up?
body: <p>I've created a custom document type (.TBVM) and can import and export such files from my app.  However, I cannot get the icon associated with that file type to show up anywhere (e.g., in iCloud, as an attachment to a text message, etc).</p>
  
  <p>Here are the parameters I have set up in .plist.  Any help in figuring out where I've gone wrong would be greatly appreciated.</p>
