using Facebook iOS SDK 2, how do I like a page? - “Application must be on whitelist”

Question

How do I \"like\" a page using the new Facebook iOS SDK? (http://github.com/facebook/facebook-ios-sdk)

I\'m currently attempting to do it with:

NSMut         


        

Answer 1

This is not a bug, it's broken by design. Using Facebook API you are only allowed to liking posts (by sending post request to https://graph.facebook.com/POST_ID/likes&auth_token=...), nothing else. Right now there is only one application which is allowed to liking pages using facebook api, it's "causes".

Answer 2

1)Use the facebook iOS SDk to check if the user is logged in.
2)Once the user is logged in, load the facebook Like API into a webview.

See http://developers.facebook.com/docs/reference/plugins/like/#
You should load something like this (format with appropiate params where you see %@, %i):

http://www.facebook.com/plugins/like.php?href=%@&layout=%@&show_faces=%@&width=%i&action=%@&colorscheme=%@&font=%@"

3)Profit.

Also, the reason the user won't have to login is because a cookie will be saved once they log in using the Facebook iOS SDK login screen (If you are doing it in your app and not Safari/FB app).

Answer 3

It looks like it's a well known, but unconfirmed, bug: http://bugs.developers.facebook.net/show_bug.cgi?id=10714.

It may help if you voted for the bug in Facebook's bug tracker.

Answer 4

Partial solutions have been suggested, though the user experience is only great if the user is already logged in to FB -- this may be likely for many but not all users, so it remains an imperfect approach.
