presenting MFMailComposeViewController modally from iPhone addressbook
<p>I am building an iPhone app which sends email to contacts from address-book.</p>

<p>After selecting the email-address from a persons contact...i want to use MFMailComposeViewController and present the MailComposeViewController modally, but on tap to email field of contact it launches the mail application....</p>

<p>how can i discard the default functionality of switching to mail app and use  MFMailComposeViewController instead?</p>
