title: iOS how to get facebook friends(Both already logged into the app and non-logged into app) userIds?
body: <p>My app has login with Facebook. And it is about dealing with share on facebook and invite friends to my app. Previously there is "me/friends" API to get all the friends list with userids, but now it is giving only app used friends(i.e the list of friends who are already login to the app) list. So i changed to me/taggable_friends API. It is giving complete friends list But it is giving taggable id, which is not constant. I want the friends userid. Is there any way to get the friends(both already logged in users and non-logged in users) UIds?</p>
