I would like to create a link to a user's Facebook profile page so that others (within the app) can access the user's profile who is also a user of the app.
The login to the app is not via Facebook login necessarily and so I am looking for a way, if there is any, to get Facebook ID without forcing users to go through login flow using the login button.
I know how to get ID if user is logged into Facebook in "didCompleteWith result" method of Facebook login button and open a Facebook profile using schemes, as addressed in here and here.
But is there any way to get the ID without forcing users to login to Facebook?
