在CAShapeLayer lineWidth上检测不到Taps事件？

class CustomView: UIView {
    private let shapeLayer = CAShapeLayer()
    
    override init(frame: CGRect) {
        super.init(frame: frame)
        setupShapeLayer()
    }
    
    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
        setupShapeLayer()
    }
    
    private func setupShapeLayer() {
        shapeLayer.path = UIBezierPath(rect: bounds).cgPath
        shapeLayer.fillColor = UIColor.red.cgColor
        layer.addSublayer(shapeLayer)
    }
    
    override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
        guard let touch = touches.first else { return }
        let touchPoint = touch.location(in: self)
        
        if shapeLayer.path != nil && shapeLayer.path!.contains(touchPoint) {
            // 在形状内部触发了点击事件
            print("Tapped inside the shape")
        }
    }
}
