Showing/Decoding received chat message XMPP framework ios

Question

I am able to send Message to specific Person selected through XMPPframework IOS. I am receiving messages from others sent to me and I can see using NSLog in following method.

- (void)xmppStream:(XMPPStream *)sender didReceiveMessage:(XMPPMessage *)message

I have gone through What I want to know is, if any method available in XMPP to directly decode received chat message ? i.e. like If

- [message getChatMessage]; 

Or we need to implement on our own ? i.e decoding received XML and get requirement element string.

Please share if any one knows.
