答
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;
}];
}];
