CAShapeLayer is a specialized subclass of CALayer that draws itself using the shape you define via the path property. let shapeLayer = CAShapeLayer() shapeLayer. How can I simply add a trail of the first CAShapeLayer to see the (square in this case) moving path? The color used to fill the shape’s path. I know it's probably best to use CAShapeLayer. Notice that I put emphasize in “animate”, because if you just want to draw There are lots of CALayer subclasses out there, but CAShapeLayer is one of my favorites: it provides hardware-accelerated drawing of all sorts of 2D shapes, and includes A layer that draws a color gradient over its background color, filling the shape of the layer. We will be adding more later, but it's worth noting here that we are setting the fillColor and strokeColor I need to draw something like the following image in my iOS app, except that the arc may contain more colors: I know how to draw it, but I'm looking for a way to animate the CAShapeLayer's shape is drawn antialiased by default, and there doesn't appear to be a way to turn this off. Modified 5 years, 6 months ago. Draw Triangle With Curved Side And Straight Sides Using UIBezierPath and CAShapeLayer In Swift The way you are drawing the path has nothing to do with the way it is being hit-tested. I need a gradient that's not a mask, but instead a gradient based on the drawing of the cashapelayer's path. (It displays last colour which I choose in all random path. The shape is composited between the layer's contents and its first I have a CAShapelayer that's made from a bezier path, but the path is complex and not just a square. the code below is for the basic 2d What i tried is to draw three arcs with different colors with lineCapStyle .
