我有这样一行：

以下代码是在CAShapelayer上绘制的：

class LineView: UIView {

    let rwPath = UIBezierPath()
    let rwLayer = CAShapelayer()
    let rwColor = UIColor(red: 11/255.0,green: 86/255.0,blue: 14/255.0,alpha: 1.0)

    func setData() {
        rwPath.move(to: CGPoint(x: 50.0,y: 50.0))
        for i in 1...200 {
            rwPath.addLine(to: CGPoint(x: i + 50,y: i + 50))
        }

        setUpRWLayer()
        layer.addSublayer(rwLayer)
    }

    private func setUpRWLayer() {
        rwLayer.path = rwPath.cgPath
        rwLayer.fillColor = nil
        rwLayer.lineCap = .butt
        rwLayer.lineDashPattern = nil
        rwLayer.lineDashPhase = 0.0
        rwLayer.lineJoin = .miter
        rwLayer.lineWidth = 3.0
        rwLayer.miterLimit = 10.0
        rwLayer.strokeColor = rwColor.cgColor
    }
}

我已经尝试了一段时间以检测该行上的点击。我已经尝试过使用UITapGestureRecognizer并覆盖touchesBegin：withEvent函数，但是似乎没有任何效果，所以我来这里询问。

命中测试代码：

override func touchesBegan(_ touches: Set<UITouch>,with event: UIEvent?) {
    let point = touches.first?.location(in: self)

    if let hitLayer = self.layer.hitTest(point!) as? CAShapelayer {
        if (hitLayer.path?.contains(point!))! {
            print("Touched")
        }
    }
}
