推荐答案

这就是iOS5 +的工作方式

Thats the way how it works with iOS5+

FBRequest* friendsRequest = [FBRequest requestWithGraphPath:@"me/friends?fields=installed" parameters:nil HTTPMethod:@"GET"];
        [friendsRequest startWithCompletionHandler: ^(FBRequestConnection *connection,
                                                      NSDictionary* result,
                                                      NSError *error) {
            NSArray* friends = [result objectForKey:@"data"];
            NSLog(@"Found: %i friends", friends.count);
            for (NSDictionary<FBGraphUser>* friend in friends) {
                NSLog(@"I have a friend named %@ with id %@", friend.name, friend.id);

            }
            NSArray *friendIDs = [friends collect:^id(NSDictionary<FBGraphUser>* friend) {
                return friend.id;
            }];

     }];
