rendererContextClass()
Specifies the drawing context class used by this graphics renderer.
Declaration
class func rendererContextClass() -> AnyClassReturn Value
A subclass of UIGraphicsRendererContext suitable for the current renderer.
Discussion
Each subclass of UIGraphicsRenderer can define its own subclass of UIGraphicsRendererContext. The graphics renderer calls this method whenever it needs to create a new graphics renderer context.
Override this method to specify the context class that the graphics renderer should use.
