The best way to do this now is to use Grand Central Dispatch. Your listening socket and the connected sockets are just a dispatch sources that can call blocks on a queue when stuff happens. I believe there's a wrapper for this on github called AsyncSocket that abstracts things a bit (on my phone so I don't have all of my notes). <span></span><br>

Has anybody written a simple objective C client that opens a port<br>
waits for a message then executes a callback. This should be non-blocking<br>
and be integrated with the "standard" dispatcher top-loop.<br>
<br>
I'm confused by the profusion of classes that almost do this.<br>
<br>
Has anybody implemented this, or have pointers to a good place to start.<br>
