Draw a line with UIBezierPath

Question

First time using BezierPaths, wondering how this function is actually supposed to be implemented. Currently the bezier path moves within the frame of the image, as opposed t

Answer 1

To draw horizontal line on top:

let path = UIBezierPath()
path.moveToPoint(CGPoint(x: 0, y: 0))
path.addLineToPoint(CGPoint(x: yourView.frame.width, y: 0))

let shapeLayer = CAShapeLayer()
shapeLayer.path = path.CGPath
shapeLayer.strokeColor = UIColor.lightGrayColor().CGColor
shapeLayer.lineWidth = 0.5

yourView.layer.addSublayer(shapeLayer)

To draw horizontal line on bottom:

let path = UIBezierPath()
path.moveToPoint(CGPoint(x: 0, y: yourView.frame.height))
path.addLineToPoint(CGPoint(x: yourView.frame.width, y: yourView.frame.height))

let shapeLayer = CAShapeLayer()
shapeLayer.path = path.CGPath
shapeLayer.strokeColor = UIColor.lightGrayColor().CGColor
shapeLayer.lineWidth = 0.5

yourView.layer.addSublayer(shapeLayer)
