iOS How can UITouch detect an animation UIImageView?

[lamfan]

window addSubview:mainView;
mainView addSubview:hitView;

mainView = UIView;
hitView = UIImageView

I had try adding UIView animation and CABasicAnimation to (UIImageView)hitView,

both of that working fine at animation, but when I add the touchesBegan method the detect touch event in (UIView)mainView,

UITouch *touch = [event allTouches] anyObject;
NSLog(@"%@", touch view);

the NSLog will only display the (UIImageView) hitView when the animation stop, if the animation is still running, it will return the (UIView)mainView.

Anyone know how to solve this problem?
