How to check and let the user "like" the page programmatically from the iphone application?

Question

I am trying to integrate an iphone application with facebook and I am stuck at the point where I need to let the user “like” the page. This is because only after Liking on the page the user can write comments that will eventually appear on the wall of the page. I cannot find a suitable C object code to implement this function. Also, how to check If the user "likes" the page (in any other way than FQL), I need to hide a similar button as soon as he likes the page.

You should check the official documentation of the Graph Graph API:

http://developers.facebook.com/docs/api

http://developers.facebook.com/docs/reference/api/

Facebook also now has an updated iPhone API for use with the graphics API:

EDIT: You might want to see with Facebook iOS SDK 2 how I like the page? - "The application must be in the white list"
