The big problem is how can i get friend_id ? is it their emails? Or how to get all lists of my friends ids

Answer 1

[_facebook requestWithGraphPath:@"me/friends" andDelegate:self];

will request the list of your friends, provided that you are correctly authenticated.

Then implement your delegate method in order to extract the id you need.

- (void)request:(FBRequest *)request didLoad:(id)result {
    items = result[@"data"];
    for (NSDictionary * friend in items) {
        long long friendId = [friend[@"id"] longLongValue];
        // Do something with the Id
    }
}
