gamekit over the internet

问题:

the gamekit over wifi documentation talks about local wifi and that it's built on top of bonjour. Does that mean it does not work over the Internet, locating user/players in a different subnet, different ISP ... etc

If I need to connect to players/users on the Internet in general I assume I need to setup a server, right ?

回答1:

YES, Game Kit can be used to connect peers over Internet.

BUT in this case your application must respond to peerPickerController:didSelectConnectionType: and handle all your private handshake protocol to discover peers and establish communication. A web service on your server is also required (unless users type in their IP address).

Good luck Sam!

there are two things:

• you can use gamekit to play with local devices using GKsessions
• you can use gamekit to play over the internet using GKmatch

both methods are very similar, but it's not the case of just changing a flag - you will have to write code for each. if you are smart, you can make a small interface which can use both, based on a flag. I've implemented it and it works fine
