drawing dashed line using CALayer

Question

I was able to draw a dashed box, using the following code:

CAShapeLayer *shapeLayer = [CAShapeLayer layer];
CGRect shapeRect = CGRectMake(0.0f, 0.0f, 200.0f,         


        

Answer 1

Below is the code snippet to draw a Dashed line in UIView (Xamarin iOS)

Note: separatorView is my UIView which i need to show as Dashed

 public void ShowDottedLine()
 {
      var dashedLayer = new CAShapeLayer();
      var frameSize = separatorView.Frame.Size;
      var shapeRect = new CGRect(0, 0, frameSize.Width, frameSize.Height);
      dashedLayer.Bounds = shapeRect;
      dashedLayer.Position = new CGPoint(frameSize.Width / 2, frameSize.Height / 2);
      dashedLayer.FillColor = UIColor.Clear.CGColor;
      dashedLayer.StrokeColor = ColorUtils.ColorWithHex(ColorConstants.DarkBlue).CGColor;
      dashedLayer.LineWidth = 2;
      dashedLayer.LineJoin = CAShapeLayer.JoinRound;
      NSNumber[] patternArray = {5,5};
      dashedLayer.LineDashPattern = Array;
      var path = new CGPath();
      path.MoveToPoint(CGPoint.Empty);
      path.AddLineToPoint(new CGPoint(frameSize.Width, 0));
      dashedLayer.Path = path;
      separatorView.Layer.AddSublayer(dashedLayer);
 }
