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

Got it working in Objective C with the simplified code as below

   //Dashed line for road
    CAShapeLayer *dashedLine = [CAShapeLayer layer];
    [dashedLine setFrame:CGRectMake(0, 342, 100 , 100)];

    // Setup the path
    CGMutablePathRef thePath = CGPathCreateMutable();
    CGPathMoveToPoint(thePath, NULL, 0, 10);
    CGPathAddLineToPoint(thePath, NULL, screenSize.width,10);
    dashedLine.path = thePath;
    CGPathRelease(thePath);

    [dashedLine setLineDashPattern: [NSArray arrayWithObjects:[NSNumber numberWithFloat:15], nil]];
    dashedLine.lineWidth = 1.0f;
    dashedLine.strokeColor =  [[UIColor redcolor] CGColor]];

    [self.view.layer addSublayer:dashedLine];
