I am developing a simple game on iPhone and I started with a View based application, and through the UIViewController
I am loading a custom UIView
that contains some more UIView
s and some UIImageView
s. I want to detect touch events on some of the UIImageView
s, but I wasn't able so far.
I've created a second project for testing purposes and figured that UIImageView
s handle touch events when the hierarchy is like : UIViewController
-> UIView
-> UIImageView
, but when it's like : UIViewController
-> UIView
-> UIView
-> UIImageView
they are not detected.
Notes:
- userInteractionEnabled
is YES
in all cases
- all UIViews
and UIImageViews
I mention above are custom subclasses.
Can you think of any reason why, when a custom UIImageView
gets deeper in the view hierarchy can't receive touch events?
