Here is my current setup. I can click a button and post an image and a comment or news story directly to my wall, mainly just doing some simple FBConnect or ShareKit options.
I would like to expand this to something more complex and engrossing/useful. I would like to be able to take a comment or news story, and either send it in a message to someone on Facebook, or post it to any of my friend's walls.
I believe I will need to use Facebook Open Graph to accomplish this, but am unsure of where to begin. I do have an App setup in Facebook, though it is essentially just for the purpose of SSO with my apps. Could someone direct me to a good tutorial to do what I would like and/or guide me through getting my app set up in Facebook, and then some suggestions for integrating with iPhone?
