  • 0

I am attempting to build a client/server game architecture and would like to begin testing the game using my local Mac as the server. I have found several articles on Bonjour, but that is for local network traffic only. My goal is to make this application work over the Internet, connecting to a hosted application on a static address to facilitate turn data. However, I’m at a loss as to which Cocoa APIs to use for this purpose. Should I use NSConnection, NSStream subclasses, or good ‘ol C sockets and whatnot. The game state is already built in Objective-C and is ready to be set in motion once I have the server facilities ready. Any insight?

    I suggest you to use sockets, since they’re not hard to use and are a standard way. I’ve even written an asynchronous wrapper class around BSD sockets: https://github.com/H2CO3/TCPHelper

    This is for simple, one-to-one TCP protocol connections, supporting both IPv4 and IPv6. You can send and receive raw NSData and possibly build a protocol around it.

    Foundation classes such as NSURLConnection are not particularily for this purpose; rather than to interact with standard HTTP servers (I suppose you don’t want to implement a full HTTP server for a game).

    NSNetServices may suit you just like CFNetwork, but the latter is a bit harder to use. If you’d like to use Foundation classes, I’d recommend NSNetServices.

    Hope it helps.
