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

Swift 3.1 Version of William Falcon's Answer + Improved

This is just an updated version of already accepted answer, and I just added a little bit more to it.

func drawLineFromPointToPoint(startX: Int, toEndingX endX: Int, startingY startY: Int, toEndingY endY: Int, ofColor lineColor: UIColor, widthOfLine lineWidth: CGFloat, inView view: UIView) {

    let path = UIBezierPath()
    path.move(to: CGPoint(x: startX, y: startY))
    path.addLine(to: CGPoint(x: endX, y: endY))

    let shapeLayer = CAShapeLayer()
    shapeLayer.path = path.cgPath
    shapeLayer.strokeColor = lineColor.cgColor
    shapeLayer.lineWidth = lineWidth

    view.layer.addSublayer(shapeLayer)

}

And of course the implementation would be

drawLineFromPointToPoint(startX: Int, toEndingX: Int, startingY: Int, toEndingY: Int, ofColor: UIColor, widthOfLine: CGFloat, inView: UIView)

What I changed from accepted answer

I changed the vars to lets, and made it easier to input the start and end of both the x and the y. I also allow the user to change the width of the line.

I chose for the values to be of type Int, but you can change those to be the other allowed options.
