Can't get Facebook friends with FBFriendPicker in iOS

Question

I want to get Facebook friends in my project. I have tried the FBFriendPicker Method, but I can't get the friends. It shows empty list to me.

Here is my code.

- (IBAction)pickFriendsButtonClick:(id)sender {

if (!FBSession.activeSession.isOpen) {
    [FBSession openActiveSessionWithReadPermissions:@[@"public_profile", @"user_friends"]
                                       allowLoginUI:YES
                                  completionHandler:^(FBSession *session,
                                                      FBSessionState state,
                                                      NSError *error) {
                                      if (error) {
                                          UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Error"
                                                                                              message:error.localizedDescription
                                                                                             delegate:nil
                                                                                    cancelButtonTitle:@"OK"
                                                                                    otherButtonTitles:nil];
                                          [alertView show];
                                      } else if (session.isOpen) {
                                          [self pickFriendsButtonClick:sender];
                                      }
                                  }];
    return;
}

if (self.friendPickerController == nil) {
    // Create friend picker, and get data loaded into it.
    self.friendPickerController = [[FBFriendPickerViewController alloc] init];
    self.friendPickerController.title = @"Pick Friends";
    self.friendPickerController.delegate = self;
}

[self.friendPickerController loadData];
[self.friendPickerController clearSelection];

[self presentModalViewController:self.friendPickerController animated:YES];
}

    [FBSession openActiveSessionWithReadPermissions:permissions allowLoginUI:YES completionHandler:^(FBSession *session,FBSessionState status,NSError *error)

         else if(FB_ISSESSIONOPENWITHSTATE(status))
         {

             [self getFriendList];

                                      FBRequest *req = [FBRequest requestForMyFriends];
                                      [req startWithCompletionHandler:^(FBRequestConnection *connection,NSDictionary *result,NSError *error){
                                          NSLog(@"Result:- %@",[result objectForKey:@"data"]);
                                      }];
                                  }

With the new API version v2.0, you cannot get the complete list of friends just with user_friends . Your picker must be using /me/friends which will give you the list of friends using that app. So in your case none of your friends be using this app and that's why you are getting a blank response.

To get the complete list of friends you should use /me/taggable_friends API. But note that this permission needs to be reviewed first by facebook before you go live. See this answer for more info for using this permission.
