title: iBooks sharing with iOS Application
body: <p>I have a question about iBooks sharing.</p>
  
  <p>I want to open a book from iBooks with my iOS Application. To create this I have specified content type:</p>
  
  <pre><code>&lt;dict&gt;
      &lt;key&gt;CFBundleTypeName&lt;/key&gt;
      &lt;string&gt;All Files&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;public.calendar-event&lt;/string&gt;
          &lt;string&gt;public.database&lt;/string&gt;
          &lt;string&gt;public.executable&lt;/string&gt;
          &lt;string&gt;public.data&lt;/string&gt;
          &lt;string&gt;public.content &lt;/string&gt;
          &lt;string&gt;public.item&lt;/string&gt;
      &lt;/array&gt;
  &lt;/dict&gt;
  </code></pre>
  
  <p>As far as I understand, this should contain all available files. Nevertheless, when I am sharing a document from iBooks, my application selection is not shown:<a href="https://drive.google.com/file/d/0B6ycu14tT4SGeExGZV9Ca3ZJeEk/view?usp=sharing" rel="nofollow">https://drive.google.com/file/d/0B6ycu14tT4SGeExGZV9Ca3ZJeEk/view?usp=sharing</a></p>
  
  <p>Where is the problem?</p>
