How can I use/implement the new Graph API from facebook in iOS programming (objective C)? Also parsing the JSON file returned by the API? I can't seem to find any examples out there. Facebook resources doesn't give too many details on iOS development.
Have you downloaded the Facebook iOS SDK from here: http://github.com/facebook/facebook-ios-sdk. It contains all you need to connect to Facebook from iOS and also sample code on how to use both the old API and the new Graph API.
