Question

it is incredibly easy to hide content from someone who does not like your application...if you re using FBML. I m using an iFrame and the JavaScript SDK, and am having terrible difficulty figuring this out.

The behavior I m seeing (both logged in and out) is that does not seem to be supported by FB.XFBML.parse(). Am I mistaken or is there an alternative method I can use that does not require the user to give explicit permission?

Finally figured it out!

After you have initialized the api (using FB.init()) simply do the following:

FB.api( /mypage , function (response) {
    FB.api({ method:  pages.isFan , page_id: response.id },
        function (response) {
            alert(response);
        });
});

When the /mypage response comes back, it has the page id of the profile. Use that in the pages.isFan call and it will return a boolean object telling you if the current user has Liked that page or not.

No need to deal with authentication, extended permissions, or any FQL.
