GCDAsyncUdpSocket + Bonjour？ （bynamic udp端口）

Question

I'm using GCDAsyncUdpSocket for my project, I can bind a port this way, (Server part)

[udpSocket bindToPort:45678 error:&error];

But I don't want to give a static port number for this. How to get available free ports for UDP communication ? I am going to publish it as a service using Bonjour ? Am I on the right track ?

Take a look at this well-done tutorial -- I did and have a product on the store that uses Bonjour because of this tutorial!
