Passing data to destination view controller with performSegue

Question

So I know that if there is a segue which is setup and activated through the storyboard, one can use the prepareForSegue method to pass data to the destination view controller.

I'm wondering if there is a way to do this if one uses the performSegueWithIdentifier method? It seems the prepareForSegue method is only called if the segue is activated with the storyboard, not with performSegue.

One particular problem is that I can't access the UIStoryboardSegue (it is not an argument in performSegue as it is in prepareForSegue), and therefore can't access the destination VC either.

Answer is here in StackOverflow. How to pass prepareForSegue: an object

// When any of buttons are pressed, push the next view
- (IBAction)buttonPressed:(id)sender
{
    [self performSegueWithIdentifier:@"MySegue" sender:sender];
}

// This will get called too before the view appears
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    if ([[segue identifier] isEqualToString:@"MySegue"]) {

        // Get destination view
        SecondView *vc = [segue destinationViewController];

        // Get button tag number (or do whatever you need to do here, based on your object
        NSInteger tagIndex = [(UIButton *)sender tag];

        // Pass the information to your destination view
        [vc setSelectedButton:tagIndex];
    }
}
