shadow
The shadow displayed underneath the view.
Declaration
@NSCopying var shadow: NSShadow? { get set }Return Value
An instance of NSShadow that is created using the shadowColor,shadowOffset, shadowOpacity, and shadowRadius properties of the view’s layer.
Discussion
The default value of this property is normally nil. When you configure any of the shadow-related properties on the view’s layer, such as the shadowColor,shadowOffset, shadowOpacity or shadowRadius properties, this property contains the NSShadow object that encapsulates that information. Assigning a new shadow object to this property sets the corresponding shadow-related properties on the view’s layer.
If the view does not have a layer, setting the value of this property has no effect.
