I am very new to CALayer thing. I had a look at the documentation, but quite don't understand the meaning of those properties which can be used to control the shadow
shadowOpacity
shadowRadius
shadowOffset
I particularly don't understand the Offset & Radius.
Can anyone give me some lights to me, for this newbie question?
Another question about the shadow is
If the UIView view1's frame is CGRect(0, 0, 768, 40), if I apply shadow on it, will the shadow possibly be covered by another UIView which is just next to the bottom edge of view1?
thanks
