Implementing a chat client for iOS?

Question

iOS

Hello, dear habravchane!
Not so long ago, I faced the task of creating an iOS client for web chat. The server itself is long-polling. The idea is very simple: a connecting user connects to another anonymous user. It turns out, as it were, a chat for two anonymous people. But how to implement it - I do not understand at all. I have the necessary requests, I have the framework of the application itself (banal: buttons, input forms, etc.). In search of the necessary material, I went around the whole google, Stack Overflow, found several lessons, but everything is different in each of them, and as a result, little is clear and almost nothing works, especially with updating xcode to version 5. The last hope for Habr remains :)
Tell me please, how can I implement such a task?
Thanks in advance.

Look at the web-socket client for iOS SocketRocket and see an example of a chat implementation there.

XMPP for iOS has been used. Quite tolerable.
