iPhone peer to peer via wifi?

Scenario:

In a Campsite, iPhone/iPods in different camp can connect, chat or share photos. I want to use wifi not bluetooth.

Since there is no wifi internet around. One of the iPod s开发者_开发技巧hould work as an wifi access point, like the concept in "wifi-direct", is it possible?

Can iOS networking library do that?

what you're looking for is called "WiFi Direct" (http://www.wi-fi.org/Wi-Fi_Direct.php). there's no reason why an iPhone couldn't support it, but it doesn't yet.

iOS 7 adds the Multipeer Connectivity Framework for exactly this purpose.
