title: How do I register my iOS app to open zip files from within the mail app in iOS 6+?
body: <p>I have an app which I've registered to open zip files by adding the following to the info.plist:</p>
  
  <pre><code>&lt;dict&gt;
      &lt;key&gt;CFBundleTypeName&lt;/key&gt;
      &lt;string&gt;Zip archive&lt;/string&gt;
      &lt;key&gt;CFBundleTypeRole&lt;/key&gt;
      &lt;string&gt;Editor&lt;/string&gt;
      &lt;key&gt;LSHandlerRank&lt;/key&gt;
      &lt;string&gt;Alternate&lt;/string&gt;
      &lt;key&gt;LSItemContentTypes&lt;/key&gt;
      &lt;array&gt;
          &lt;string&gt;com.pkware.zip-archive&lt;/string&gt;
      &lt;/array&gt;
  &lt;/dict&gt;
  </code></pre>
  
  <p>In iOS 5, this was enough that the mail app would offer to open zip files in my app.  In iOS 6, it's not; the file doesn't use my app's icon and my app doesn't appear in the list. (It does use the icon in mail compose views, though)</p>
  
  <p>I've tried changing the <code>CFBundleTypeRole</code> to Viewer, and the <code>LSHandlerRank</code> to Default and even to Owner.  Do I need to add something else to get it to work in iOS 6?  Or have they just removed the ability to open zip files from the mail app?</p>
