Is it possible to build socket connection between 2 iOS devices

Question

Is it possible to build a socket connection between 2 iOS devices connected to the same network (Without net)?

if it\'s possible .. Is (CocoaAsyncSocket project) useful

Answer 1

Yes, you can do it, and yes, CocoaAsyncSocket would be useful. If you don't have to worry about the carrier network's firewalls and filters, then you should certainly be able to build a client-server app running on two iOS devices. One opens the server socket to listen, and the other one (the client) connects, via the Wi-Fi network.

Trying searching on Google (e.g. "CocoaAsyncSocket iPhone iOS site:stackoverflow.com") or directly here on Stack Overflow.

Here's somebody who seems to have accomplished this

And a post from Robbie Hanson himself, referring you to the EchoServer projects in the github repository

You may have to use a static IP address for the server device (I'm not sure how much control you have over the Wi-Fi network's configuration), or use some other mechanism for letting the two devices discover each other.
