将bezier路径居中放置到UIview？

import UIKit

class ViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // 创建UIView对象
        let view = UIView(frame: CGRect(x: 0, y: 0, width: 200, height: 200))
        view.backgroundColor = UIColor.white
        
        // 创建CAShapeLayer对象
        let shapeLayer = CAShapeLayer()
        shapeLayer.fillColor = UIColor.red.cgColor
        
        // 创建UIBezierPath对象，并绘制路径
        let bezierPath = UIBezierPath()
        bezierPath.move(to: CGPoint(x: 0, y: 100))
        bezierPath.addCurve(to: CGPoint(x: 200, y: 100), controlPoint1: CGPoint(x: 50, y: 0), controlPoint2: CGPoint(x: 150, y: 200))
        bezierPath.addLine(to: CGPoint(x: 200, y: 200))
        bezierPath.addLine(to: CGPoint(x: 0, y: 200))
        bezierPath.close()
        
        // 将UIBezierPath与CAShapeLayer关联起来
        shapeLayer.path = bezierPath.cgPath
        
        // 设置路径的位置和大小
        shapeLayer.frame = CGRect(x: (view.bounds.width - 200) / 2, y: (view.bounds.height - 200) / 2, width: 200, height: 200)
        
        // 将CAShapeLayer添加到UIView的layer中
        view.layer.addSublayer(shapeLayer)
        
        // 将UIView添加到当前视图控制器的view中
        self.view.addSubview(view)
    }
