I admire your perseverance in programming for iOS though blind. I'm not sure I'd do as well.
UIImageView is not a control, so it doesn't have built-in handlers for touches that would feed a target-action pair. You'll have to make a subclass of UIImageView (in my experience it tolerates subclassing well), and add your own touchesBegan/Moved/Cancelled/Ended methods.
