Making UIProgressView Rounded corners

Question

I have created a UIProgressView with following properties

progressView.progressTintColor = UIColor.appChallengeColorWithAlpha(1.0)
progressView.trac         


        

Answer 1

Swift 4.2 version from Umair Afzal's solution

class CustomHorizontalProgressView: UIView {

var strokeColor: UIColor?

var progress: CGFloat = 0.0 {
    didSet {
        setNeedsDisplay()
    }
}

override init(frame: CGRect) {
    super.init(frame: frame)
    setup()
}

required init?(coder aDecoder: NSCoder) {
    super.init(coder: aDecoder)
    setup()
}

func setup() {
    self.backgroundColor = UIColor.clear
}

override func draw(_ rect: CGRect) {
    super.draw(rect)
    setProgress()
}

func setProgress() {

    var progress = self.progress
    progress = progress > 1.0 ? progress / 100 : progress

    self.layer.cornerRadius = frame.size.height / 2.0
    self.layer.borderColor = UIColor.gray.cgColor
    self.layer.borderWidth = 1.0

    let margin: CGFloat = 6.0
    var width = (frame.size.width - margin)  * progress
    let height = frame.size.height - margin

    if (width < height) {
        width = height
    }

    let pathRef = UIBezierPath(roundedRect: CGRect(x: margin / 2.0, y: margin / 2.0, width: width, height: height), cornerRadius: height / 2.0)

    strokeColor?.setFill()

    pathRef.fill()
    UIColor.clear.setStroke()
    pathRef.stroke()
    pathRef.close()
}
}

And to use it

var progressView: CustomHorizontalProgressView = {
    let view = CustomHorizontalProgressView()
    view.strokeColor = UIColor.orange
    view.progress = 0.5
    return view
}()
