如何让UIView在NavBar滚动过屏幕时自动滚动？

import UIKit

class ViewController: UIViewController, UIScrollViewDelegate {
    
    let scrollView = UIScrollView()
    let contentView = UIView()
    let myView = UIView()
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // 设置UIScrollView的属性
        scrollView.delegate = self
        scrollView.translatesAutoresizingMaskIntoConstraints = false
        view.addSubview(scrollView)
        
        // 设置UIScrollView的约束
        scrollView.leadingAnchor.constraint(equalTo: view.leadingAnchor).isActive = true
        scrollView.trailingAnchor.constraint(equalTo: view.trailingAnchor).isActive = true
        scrollView.topAnchor.constraint(equalTo: view.topAnchor).isActive = true
        scrollView.bottomAnchor.constraint(equalTo: view.bottomAnchor).isActive = true
        
        // 设置contentView的属性
        contentView.translatesAutoresizingMaskIntoConstraints = false
        scrollView.addSubview(contentView)
        
        // 设置contentView的约束
        contentView.leadingAnchor.constraint(equalTo: scrollView.leadingAnchor).isActive = true
        contentView.trailingAnchor.constraint(equalTo: scrollView.trailingAnchor).isActive = true
        contentView.topAnchor.constraint(equalTo: scrollView.topAnchor).isActive = true
        contentView.bottomAnchor.constraint(equalTo: scrollView.bottomAnchor).isActive = true
        contentView.widthAnchor.constraint(equalTo: scrollView.widthAnchor).isActive = true
        
        // 添加你的UIView到contentView中
        myView.translatesAutoresizingMaskIntoConstraints = false
        contentView.addSubview(myView)
        
        // 设置你的UIView的约束
        myView.leadingAnchor.constraint(equalTo: contentView.leadingAnchor).isActive = true
        myView.trailingAnchor.constraint(equalTo: contentView.trailingAnchor).isActive = true
        myView.topAnchor.constraint(equalTo: contentView.topAnchor).isActive = true
        myView.heightAnchor.constraint(equalToConstant: 200).isActive = true
        
        // 设置UIScrollView的contentSize以确保能够滚动
        contentView.bottomAnchor.constraint(equalTo: myView.bottomAnchor).isActive = true
        
        // 其他设置和布局代码...
    }
    
    // UIScrollViewDelegate代理方法
    func scrollViewDidScroll(_ scrollView: UIScrollView) {
        // 获取滚动的偏移量
        let offsetY = scrollView.contentOffset.y
        
        // 根据偏移量计算UIView应该滚动的距离
        let scrollDistance = offsetY - myView.frame.origin.y
        
        // 修改UIView的约束或frame来实现滚动效果
        myView.transform = CGAffineTransform(translationX: 0, y: scrollDistance)
    }
}
