Facebook iOS SDK - get friends list

Question

Using the Facebook iOS SDK, how can I get an NSArray of all my friends and send them an invitation to my app? I am specifically looking for the graph path to get all of the friends.

With Facebook SDK 3.0 you can do this:

FBRequest* friendsRequest = [FBRequest requestForMyFriends];
[friendsRequest startWithCompletionHandler: ^(FBRequestConnection *connection,
                                  NSDictionary* result,
                                  NSError *error) {
    NSArray* friends = [result objectForKey:@"data"];
    NSLog(@"Found: %lu friends", (unsigned long)friends.count);
    for (NSDictionary<FBGraphUser>* friend in friends) {
        NSLog(@"I have a friend named %@ with id %@", friend.name, friend.objectID);
    }
}];
