title: Is it possible to edit .ePub file via iPad application?
body: <p>Requirement of the iPad app is to display an <code>ebook</code> that allows user to edit and save it. Further requirements are like navigation and bookmarks. In precise, just similar to the <strong>iBooks</strong> app.</p>
  
  <p>My question is, is it possible to edit the <code>.epub</code> file? I believe we can edit <code>.pdf</code> files (As I have seen some apps available on iTunes). I tried searching on google, all I could find out is, how to display ePub file and how to customize the look of ePub file. Any suggestion would be great.</p>
