title: Locking the Fields in MFMailComposeViewController
body: <p>Is it possible to somehow lock the fields in an <code>MFMailComposeViewController</code> so that the body, recipients etc cannot be changed by the user?  I need the e-mail the user sends to go to a particular account and the body to meet certain criteria so if the user drastically edits the format everything could go horribly wrong..At the moment the body is filled in from data that the user inputs to textfields and date-pickers in the previous view.</p>
  
  <p>Basically I think it would just be more professional to have the fields locked rather than display an alert or something saying "Please Don't Edit the Message", so its not a massive problem if the fields can't be locked, but any help would be greatly appreciated.</p>
