In my book, I actually give a solution to this (in the Touch Delivery section of the Touches chapter): set the UIImageView's userInteractionEnabled to YES and attach a UITapGestureRecognizer to it or to its superview. If you attach the UITapGestureRecognizer to the superview, you can use hit-testing to determine whether the UIImageView was tapped:
CGPoint p = [g locationOfTouch:0 inView:self]; // g is the gesture recognizer
UIView* v = [self hitTest:p withEvent:nil];
m.
