How can I detect a touch on an animated subview ? Or click an animated UIButton?

问题

I have a view that is moving. The view is sometimes on and sometimes off screen - it is twice the width of the screen. In this view, there are buttons that I need to be able to click. I've tried doing this in many ways already - using pure buttons using touches began on UIView

I'm doing the animation using a CGPath in core animation

Any help would be most appreciated

Thanks

Whether the view is moving or not should irrelevent to the touch detection. If you have a UIButton object and are handling the UIEventControlTouchUpInside (forgot the exact name) event , it should be called when it sees a touch. Is that not working for you?
