I have an application which I am using for one-to-one chat. Now I need to implement group chat. I know it is possible with XMPPFramework and there is a class called XMPPRoom
here you have a script that allows to connect to a room
[xmppRoom activate:[self xmppStream]]; [xmppRoom createOrJoinRoom];
In order to do this you should have access to the xmppStream.
