如何在iPhone应用程序上使用Facebook凭据登录？

Question

I have a web application that authenticates users against Facebook. Once my site redirects them to login with Facebook, FB redirects them back to my site with a valid session cookie. This is a PHPCOOKIE I guess.

I would like to accomplish the same thing from my iPhone application. I have looked at the Facebook iPhone SDK, but that simply lets the iPhone application directly call the graph API.

What I actually want to do is have my backend server call the graph API like it does with the browser.

How do I get the iPhone SDK to pass the session cookie to all requests to my server, the same way the browser does?

This does actually occur- but you're on the iPhone, and the iPhone caches the "cookie" with auth info. It's in NSDefaults. It's also called single-sign-on or SSO. It detects Facebook login and authentication on the native app on the same device, and sets a local (iPhone app default) access token for further graph requests.
