Instance Property

mask

An optional view whose alpha channel is used to mask a view’s content.

Declaration

var mask: UIView? { get set }

Discussion

The view’s alpha channel determines how much of the view’s content and background shows through. Fully or partially opaque pixels allow the underlying content to show through but fully transparent pixels block that content.
