How can I implement my own custom MFMailComposeView?

Question

I've been playing around with a lot of apps recently and one that has caught my attention is boxes. They've somehow managed to implement their own custom MFMailComposeView.

As you can see below, they've implemented their own custom brown header bar and in the body section; added meta data about the app version, ios version and the phone with greyed out text. How can I go about doing this?

Overly simple:

mailViewController.navigationBar.tintColor = [UIColor purpleColor]; // whatever
[mailViewController setMessageBody:@"<hr /><p>Foo Bar</p>" isHTML:YES];
