I want to create a chat application that uses Ejabberd as the server. I setup the ejabberd on my laptop Ubuntu 12.04 and port forward to my public ip. I try to use Pidgin(Ubuntu), Adium(MacOS), IM+(Andriod, IOS). All of them can connect and chat with each other.

However, when I follow the tutorial here http://mobile.tutsplus.com/tutorials/iphone/building-a-jabber-client-for-ios-xmpp-integration/ to build my own chat app. I got a number of issues that cant let me chat with other accounts.

Here are the messages sent and received:

Here are what I observed:

When I turn off the ejabberd server, the client app stops working.
This mean it tried to connect to the server.
On Android, Ubuntu, and MacOS, everytime I login it ask for accepting
a certificate. But I dont see it on MY iOs app.
It seems that after success, it renegotiates and doesnt receive any response.
On the web admin of ejabberd, I dont see any online user. However, I see request is coming in the log.
What documents and steps should I follow to debug XMPP application on iOS?

I’m using XCode 4.3.2 iOS 5.1 Ejabberd 2.1.11 on Ubuntu (Linux 32 bits). I tried to debug and google for 2 days but no clue
