method from the superclass
passing the width
and the heght
of the RoundButton object, try using super.init(width: width, height: height)
instead of super.init(width:Double, height:Double)
:
class Button {
var width: Double
var height: Double
init(width:Double, height:Double){
self.width = width
self.height = height
}
func scaleBy(points: Double){
width += points
height += points
}
}
class RoundButton: Button {
var cornerRadius: Double
init(width:Double,height:Double,cornerRadius:Double){
self.cornerRadius = cornerRadius
super.init(width: width, height: height)
}
}
