UIBezierPath只有一半的中风

Question

当我尝试使用以下代码绘制如下形状时，形状仅显示半笔划线。

require 'watir'

browser = Watir::Browser.new

browser.goto('https://tripadvisor.com/CheapFlightsHome')
browser.text_field(name: 'orig').set('Boston, MA - Logan International Airport (BOS)')
browser.text_field(name: 'dest').set('Milan, Italy - All Airports (MIL)')
browser.execute_script('document.querySelector(".in_date").click()')
browser.execute_script('document.querySelector(".day_28").click()')
browser.execute_script('document.querySelector(".out_date").click()')
browser.execute_script('document.querySelector(".day_2").click()')
browser.span(id: "CHECK_FARES_BUTTON").fire_event :click
puts browser.url
browser.quit

创建形状：

LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient, mLocationRequest, this);

如果我将x设置为10，它会显示另一半的stroe线，但形状没有关闭。

let shape = SKShapeNode()
            shape.path = createPointerPath().cgPath
            shape.position = CGPoint(x: frame.midX, y: frame.midY)
            shape.fillColor = UIColor(red: 1.0, green: 0.439, blue: 0.678, alpha: 1.0)
            shape.strokeColor = .white
            shape.lineWidth = 2
            addChild(shape)

有什么建议吗？ THX！

这是我尝试后得到的;希望它可以帮到你

    let v : UIView = UIView.init(frame: CGRect.init(x: 50, y: 50, width: 200, height: 200))
    v.layer.borderWidth = 2.0
    let shape = CAShapeLayer()
    shape.path = createPointerPath().cgPath
    shape.position = CGPoint(x: frame.midX, y: frame.midY)
    shape.fillColor = UIColor(red: 1.0, green: 0.439, blue: 0.678, alpha: 1.0).cgColor
    shape.strokeColor = UIColor.white.cgColor
    shape.lineWidth = 2
    v.layer.addSublayer(shape)
    self.addSubview(v)

你给的是同样的功能：

func createPointerPath() -> UIBezierPath {

    let pointerPath = UIBezierPath()
    pointerPath.move(to: CGPoint(x:0, y:0))

    pointerPath.addCurve(to: CGPoint(x:0, y:100), controlPoint1: CGPoint(x:-10, y:0), controlPoint2: CGPoint(x:-50, y:100))
    pointerPath.addCurve(to: CGPoint(x:0, y:0), controlPoint1: CGPoint(x:50, y:100), controlPoint2: CGPoint(x:10, y:0))

    pointerPath.stroke()
    pointerPath.close()
    return pointerPath
}

输出：
