How get list of friends and email using Facebook sdk

Question

I have a problem i implement Facebook SDK in my view controller and want to get list of friends and email using Facebook. I wrote this:

FBLoginView *loginView = [[FBLoginView alloc] initWithReadPermissions:@[@"public_profile", @"email", @"user_friends"]];

loginView.delegate = self;

and then use the protocol method of FBLoginViewDelegate:

- (void)loginViewFetchedUserInfo:(FBLoginView *)loginView
                            user:(id<FBGraphUser>)user 
{
  self.profilePictureView.profileID = user.id;
  self.nameLabel.text = user.name;
  NSLog(@"%@", user);
  NSLog(@"%@", [user objectForKey:@"email"]);
}

In console i got this:

2014-12-04 14:56:48.746 FBLoginUIControlSample[2941:613] 

"first_name" = Pavel;
gender = male;
id = 1379600000000000;
"last_name" = name;
link = "https://www.facebook.com/app_scoped_user_id/1379600000000000/";
locale = "ru_RU";
name = "Pavel name";
timezone = 2;
"updated_time" = "2014-12-03T11:47:13+0000";
verified = 1;

2014-12-04 14:56:48.748 FBLoginUIControlSample[2941:613] (null)

This is not possible, and never was. @ingrid's answer is correct. — Tobi, Dec 04 '14 at 13:54
@Tobi I read this from here [link](http://www.appcoda.com/ios-programming-facebook-login-sdk/) — Сергей Олейнич, Dec 04 '14 at 13:57
There's nowhere said that you can get the email of friends. https://developers.facebook.com/docs/apps/changelog#v2_0_permissions — Tobi, Dec 04 '14 at 14:01
@Tobi I don't need the friends email. I need to get only my email and my list of friends. but z can't get this info. and i don't understand why... — Сергей Олейнич, Dec 04 '14 at 14:11
Then this was a missunderstanding. You are aware that you can only get friends which use the same app? If there aren't any, you'll see none. — Tobi, Dec 04 '14 at 14:24
@Tobi I only want when i login in my app in console i see all my friends from facebook — Сергей Олейнич, Dec 04 '14 at 14:32
you can´t get ALL friends anymore. only those who authorized your app, as tobi said. — andyrandy, Dec 04 '14 at 18:46

sorry , but you can't

Read Facebook Permissions

you only can get the email when the user login , but you can't get user's friends email.

i am not really sure but maybe you can use "friendsusername"@facebook.com ("facebook email").

i found this, https://www.facebook.com/help/224049364288051

the person has to active @facebook option.

No, you can't get the "Facebook email" – Tobi Dec 04 '14 at 14:02

For 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: %i friends", friends.count);
    for (NSDictionary<FBGraphUser>* friend in friends) {
        NSLog(@"I have a friend named %@ with id %@", friend.name, friend.id);
    }
}];

You can not access to any users email, excepts of yours.
Because FBGraphUser doesn't have an email @property, we can't access the information like with the name (dot-syntax), however the NSDictionary still has the email kv-pair and we can access it like we would do with a normal NSDictionary. With this method you can access to your email.

if (FBSession.activeSession.isOpen) {
    [[FBRequest requestForMe] startWithCompletionHandler:^(FBRequestConnection *connection, NSDictionary<FBGraphUser> *user, NSError *error) {
         if (!error) {
             self.nameLabel.text = user.name;
             self.emailLabel.text = [user objectForKey:@"email"];
         }
     }];
}

That's not gonna work. Friends permissions have been dismissed with the v2.0 Graph API, and getting the email addresses of friends was **never** possible, even with v1.0 — Tobi, Dec 04 '14 at 13:56

hope this will help you

you can get your friend list by using below code in your viewDidLoad

[FBRequestConnection startWithGraphPath:@"me/taggable_friends"
                                 parameters:nil
                                 HTTPMethod:@"GET"
                          completionHandler:^(
                                              FBRequestConnection *connection,
                                              id result,
                                              NSError *error
                                              ) {

                          }];

and some info

EDIT

the above answer only mention for friendlist not email(as its already quite clear by above answers) , now what you want friendlist

A friend list(Friend List V 2.2) - an object which refers to a grouping of friends created by someone or generated automatically for someone (such as the "Close Friends" or "Acquaintances" lists)

from v2.0 you'll only be able to get all friends via the /me/taggable_friends (see it by result)

This will only return friends who also use the app you are using. Plus, you don't get their email addresses. — Fogmeister, Dec 04 '14 at 13:53
...also, this is only for tagging friends, you are not allowed to use it for anything else. — andyrandy, Dec 04 '14 at 14:16
Please how can I use this in the 4.7 version? What is its equivalence? — Ne AS, Jul 04 '17 at 16:09
