How to Tag friends to user post in Facebook in objective C

Question

I am trying to post texts and image using Facebook Feed Dialog , I am able to post to my own wall but not able to tag friends . I am able to choose a friend from FBFriendPickerViewController , but when i click done but i am getting return error 5 . In one of stackoverflow questions (ios-Facebook SDK 3.0 Error 5 When Posting Status Update) there were a few ways where one can get this error , I have corrected all the possible ways which was mentioned in that question .

and is the feed dialog correct [FBRequestConnection startWithGraphPath:@"%@/feed" parameters:params

This is my code ,

- (IBAction)pickFriendsList:(UIButton *)sender
{
    FBFriendPickerViewController *friendPickerController = [[FBFriendPickerViewController alloc] init];
    friendPickerController.title = @"Pick Friends";
    [friendPickerController loadData];

    [friendPickerController presentModallyFromViewController:self animated:YES handler:
     ^(FBViewController *sender, BOOL donePressed) {

         if (!donePressed) {
             return;
         }

         NSString* fid;
         NSString* fbUserName;

         for (id<FBGraphUser> user in friendPickerController.selection)
         {
             NSLog(@"\nuser=%@\n", user);
             fid = user.id;

             fbUserName = user.name;

             NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys:@"aaaaaa", @"message", @"http://webecoist.momtastic.com/wp-content/uploads/2009/01/nature-wonders.jpg", @"picture", @"My Susfsdfsdfs sdf sfsdfp", @"name", nil];

             NSLog(@"\nparams=%@\n", params);


             [FBRequestConnection startWithGraphPath:@"%@/feed" parameters:params HTTPMethod:@"POST"
                                   completionHandler:^(FBRequestConnection *connection, id result, NSError *error)


              {
                  //Tell the user that it worked.
                  UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Shared"
                                                                      message:[NSString stringWithFormat:@"Invited %@! error=%@", fbUserName, error]
                                                                     delegate:nil
                                                            cancelButtonTitle:@"OK"
                                                            otherButtonTitles:nil];

                  [alertView show];
                  NSLog(@"%@ alertview description",alertView.message);

              }
              ];

         }

     }];

}

Note: you are missing FB User ID in your code

Change your code as below:

[FBRequestConnection
             startWithGraphPath:[NSString stringWithFormat:@"%@/feed", fid]
             parameters:params
             HTTPMethod:@"POST"
             completionHandler:^(FBRequestConnection *connection,
                                 id result,
                                 NSError *)

You can use checkins or, Open Graph actions to tag friends in facebook, for checkins the app will require permission for that, but will work with basic app settings. But for Open Graph there are multiple settings you will have to do.. You can have a look into here

`feed` is normally used for the user feed. You need to pass parameter on `%@` to tell facebook on which user's wall you are posting, here you need to give your friend's userid, or if you want to post on your wall it would be `me/feed`. So it should look like `/feed`. – iphonic Apr 15 '13 at 06:57
