title: List apps in the App Store that can support a given file type
body: <p>I am working on a app which needs to open/preview a file using <code>UIDocumentInteractionController</code>. One of the clients requirement is that, in case there is no installed app which can support a given file type, then the app should redirect the user to the App Store, displaying a list of apps which can open the file. </p>
  
  <p>Is that possible? If yes, could you give me a step-by-step approach ?</p>
