Question

I can get the friendlist by

But the list contain all the friends, how could I get the friendlist that only played the app.

Answer 1

This gives you a list of your friends that have the app installed

friend.getAppUsers()

Answer 2

You can query the OpenGraph for the field installed:

[facebook requestWithGraphPath:@"me/friends?fields=installed,name"
                                             andParams:params
                                         andHttpMethod:httpMethod
                                           andDelegate:delegate]; 

That will return you a list of friends, in which some will have the field installed=1
