Testing if user has liked my page in angulike

Question

Hi I am using the Angular plugin "angulike". I would like to test whether a user has liked my page or not. If he does not something should pop up.

Which way is the best to test whether user has liked my page?

A thought: I thought about testing for css classes. They are different in the two cases, but it not seem to be the best approach

Answer 1

Incentivizing likes is not allowed anymore, and not possible. You would need to authorize a user with the user_likes permission to get his Page likes, and Facebook will not approved it in the review process just for that.
