ios5 how to pass prepareForSegue: a UIImageView

Question

I want to pass my UIImageView that has a image loaded into it from clicking a button to a different UIImageView in a different ViewController.

Here is my code

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
// Make sure your segue name in storyboard is the same as this line
if ([[segue identifier] isEqualToString:@"MY_SEGUE"])
{
    // Get reference to the destination view controller
    ViewControllerName *vc = [segue destinationViewController];

    // Pass the current UIImageView to a different UIImageView in a different view controller
    [vc setUIImageView:UIImageView2];
}
}

So far when I run this nothing happens when I load the next view. I have no Errors. Do I need to say something in the - (void)viewDidLoad for this to work?

Any tips or suggestions???

Thanks
