I have iframe application, and with this new facebook user can come to application without adding or authorizing the application. I can check that by looking at the fb_sig_added value. If the user didn't authorize or didn't add the application I want
to force him/her to authorize. How can I do that with iframe app?
It would be perfect to find solution that works with old version api (my current iframe app) , but the one works with new api also appreatiated.
Is there any sample or any code at anywhere? I have been searhing all day and could not find anything even close. This sample iframe application is too simple and did not even work in my case.
