Instance Property

cornerRadius

The radius to use when drawing rounded corners for the layer’s background. Animatable.

Declaration

@property CGFloat cornerRadius;

Discussion

Setting the radius to a value greater than 0.0 causes the layer to begin drawing rounded corners on its background. By default, the corner radius does not apply to the image in the layer’s contents property; it applies only to the background color and border of the layer. However, setting the masksToBounds property to YES causes the content to be clipped to the rounded corners.

The default value of this property is 0.0.
