How to limit friend selection in FBFriendPicker?

I'm Using Facebook SDK in my app I'm trying to limit friend selection to specified number in Facebook FriendPicker? I'm trying this code:-

 - (void)friendPickerViewControllerSelectionDidChange:
      (FBFriendPickerViewController *)friendPicker
    {
        if ([friendPicker.selection count] >= 3) {
            UIAlertView *alertView = 
                [[UIAlertView alloc] initWithTitle:@""
                                           message:@"Max number of friends selected."
                                          delegate:self cancelButtonTitle:@"OK"
                                              otherButtonTitles:nil];
            [alertView show];
        }
    }

    - (void)alertView:(UIAlertView *)alertView 
       clickedButtonAtIndex:(NSInteger)buttonIndex
    {
        [self dismissViewControllerAnimated:YES completion:nil];
    }

I get the alert but I cant dissmiss the FBFriendpickercontroller Any idea why?

got it !!!!!!! solution was simpler than i imagined. you friendPickerController is a tableView so we can set userInteractionEnabled property to NO.

- (void)friendPickerViewControllerSelectionDidChange:
(FBFriendPickerViewController *)friendPicker
{
    if ([friendPicker.selection count] <=3)
    {
        self.friendPickerController.tableView.userInteractionEnabled=YES;
    }

if ([friendPicker.selection count] >=3)
{
    UIAlertView *maxFriendsAlert =
    [[UIAlertView alloc] initWithTitle:@"Max number of friends selected."
                               message:@"no more friends can be selected,"
                              delegate:self cancelButtonTitle:@"OK"
                     otherButtonTitles:@"Buy more friends",nil];
    [maxFriendsAlert show];
    maxFriendsAlert.tag=1;

// disable friends selection
        self.friendPickerController.tableView.userInteractionEnabled=NO;
    }
