Instance Property

allowsEdgeAntialiasing

A Boolean indicating whether the layer is allowed to perform edge antialiasing.

Declaration

var allowsEdgeAntialiasing: Bool { get set }

Discussion

When the value is true, the layer is allowed to antialias its edges, as requested by the value in the layer’s edgeAntialiasingMask property. The default value is read from the boolean UIViewEdgeAntialiasing property in the main bundle’s Info.plist file. If no value is found, the default value is false.
