Registering touch events of layered uiimageviews with overlapping transparent properties

I'm new at this and have looked at several posts already related to this question but none seem to provide the answer I need.

I have multiple layered uiimageviews within one "base" uiimageview. The uiimageviews display arrays of images with small opaque colored parts and large transparent parts. How do I get a touch event to ignore the layers of transparent parts to activate the opaque underlayer?



By default, the userInteractionEnabled property of UIImageView is disabled. If you want only the "lowest" view to receive touch events, you should create a subclass of UIImageView in which you explicitly set userInteractionEnabled = YES; and implement touchesBegan, etc. Let me know if you have any questions.
