Hello, I'm new here ! I'm looking for anwsers about facebook API. I have an IOS app and a facebook account. I post news about the app on the facebook account. What I would like to know is : Do my app users liked my facebook posts. How many users liked my facebook posts prior to downloading my app. What is the best way to achieve this ? My idea : Making a facebook connect in my app to get all the users likes and send it to a webservice in order to parse it and find if they liked my posts urls.
