title: how to save data from ios app so it could be exported in an excel file
body: <p>In my ios app, I have a form with radio buttons. Each time I fill the form, I would like to save the answers in the device (with an id for each user) so can later export all the choices in an excel file. How can I do that?</p>
  
  <p>p.s I developed the app using MyEclipse.</p>
