title: Open PDF stored in the iBooks application or some other
body: <p>Im working on a PDF application for the iPad and would like to present the user with a list of available PDF files on the device. I feel that it would be nice if I was able to reuse the PDF files already stored on the device for example in the iBooks application instead of having to set up a separate library of PDFs just for my own app. </p>
  
  <p>Does anyone know if this is possible and if it is could help to point me in right direction on where to continue my search. If it is not possible does anyone have a suggestion on another way to have a more unified file system approach on this problem rather than application specific?</p>
  
  <p>If i find a solution somewhere else i will off course post the solution here as well. </p>
