Instance Property

maskView

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

Declaration

@property(nonatomic, strong) UIView *maskView;

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.
