Ios 如何更改Swift2中CGRect的边框样式？

我正在学习Swift，我的设计师给了我一个这样的屏幕

我面临的问题是如何更改此虚线形式中总积分

CGRect

的边框样式

我的代码是：

override func viewDidLoad()
{
    let promobox =  UIView()

    promobox.frame = CGRectMake(16, promotextfield.frame.minY + 180, self.view.frame.width - 32, 60)
    promobox.layer.borderColor = UIColor(red: 0, green: 0, blue: 0, alpha: 0.2).CGColor
    promobox.layer.borderWidth = 2.0
    promobox.layer.backgroundColor = UIColor(red: 255, green: 255, blue: 255, alpha: 0.2).CGColor

    //background color of box
    self.view.addSubview(promobox)
}

这就是你可以做到的：

let promobox =  UIView()

promobox.frame = CGRectMake(16, 50, self.view.frame.width - 32, 60)
promobox.layer.borderColor = UIColor.whiteColor().CGColor
promobox.layer.borderWidth = 2.0
promobox.layer.backgroundColor = UIColor(red: 255, green: 255, blue: 255, alpha: 0.2).CGColor

let border = CAShapeLayer.init()
border.frame = promobox.bounds
border.path = UIBezierPath(rect: border.frame).CGPath
border.lineWidth = 2
border.strokeColor = UIColor(red: 0, green: 0, blue: 0, alpha: 0.2).CGColor
border.fillColor = UIColor.clearColor().CGColor
border.lineDashPattern = [4, 6]
promobox.layer.addSublayer(border)

---

使用

lineDashPattern

来满足设计师的期望。

这就是您可以做到的：

let promobox =  UIView()

promobox.frame = CGRectMake(16, 50, self.view.frame.width - 32, 60)
promobox.layer.borderColor = UIColor.whiteColor().CGColor
promobox.layer.borderWidth = 2.0
promobox.layer.backgroundColor = UIColor(red: 255, green: 255, blue: 255, alpha: 0.2).CGColor

let border = CAShapeLayer.init()
border.frame = promobox.bounds
border.path = UIBezierPath(rect: border.frame).CGPath
border.lineWidth = 2
border.strokeColor = UIColor(red: 0, green: 0, blue: 0, alpha: 0.2).CGColor
border.fillColor = UIColor.clearColor().CGColor
border.lineDashPattern = [4, 6]
promobox.layer.addSublayer(border)
