How can I detect touch events on a UIImageView inside a deep hierarchy of UIViews?

Question

I am developing a simple game on the iPhone, and I started with a View-based application, and through I UIViewControllerload a custom UIViewone that contains several more UIViewand some UIImageViews. I want to detect touch events on some of UIImageViews, but so far I have not been able to.

I created a second project for testing and realized that it UIImageViewhandles touch events when the hierarchy is similar:

UIViewController→ UIView→ UIImageView,

but when you like it:

UIViewController→ UIView→ UIView→UIImageView

they are not detected.

Notes:
 - userInteractionEnabled YESin all cases
 - all UIViewsand UIImageViewsI mention above are user subclasses.
