How to hide the message content on the MFMessageComposeViewController control

I'm developing an Mobile Banking app on iPhone. This app use SMS message to sen开发者_如何学JAVAd and receive data with server. (This app of a bank)

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).

Is it possible to hide the content of message on the MFMessageComposeViewController control?

I found one app on App Store can custom the MFMessageComposeViewController control:

How to custom this control?.

I don't think you want that control. I would google for "programmatic sms". I found this

I dont think you can hide the interface or any UI items from the MFMessageComposeViewController as it is provided to you by the iphone itself. So,what you can do is make a similar interface and then use other methods such as using third party web solution to send mail.
