title: I'm trying to get my iPhone app into native share menus. Photo selection menu on iOS7 and other share menus
body: <p>I'm trying to add some import options to an app. I'd like to add my app's icon to certain menus, to allow ease of importing files into my app. 
  I'm able to insert my app's icon in the "open in..." menus using CFBundleDocumentTypes. I can't find any mention of methods to get into the photo menu though. (See screen shot below)</p>
  
  <p>Does anyone know how this can be done? It seems possible, because the flickr app icon was inserted there after installing the Flickr app.</p>
  
  <p>thanks.</p>
