How to hide the message content on the MFMessageComposeViewController control
<p>I'm developing an Mobile Banking app on iPhone. This app use SMS message to send and receive data with server.
(This app of a bank)</p>

<p>I'm using the MFMessageComposeViewController control to send SMS to server.
The message content has been encrypted.
So, I don't want user can see the message content (I want to hide the message content on this control).</p>

<p>Is it possible to hide the content of message on the MFMessageComposeViewController control?</p>

<p>I found one app on App Store can custom the 
MFMessageComposeViewController control:</p>

<p>Thanks</p>
