如何在UITableViewController中引用自定义UIView的子视图按钮

// CustomView.swift

import UIKit

class CustomView: UIView {
    // 添加自定义的子视图按钮
    let button: UIButton = {
        let button = UIButton()
        button.setTitle("自定义按钮", for: .normal)
        button.backgroundColor = .blue
        button.addTarget(self, action: #selector(buttonTapped), for: .touchUpInside)
        return button
    }()
    
    // 子视图按钮的点击事件
    @objc func buttonTapped() {
        print("自定义按钮被点击")
    }
    
    override init(frame: CGRect) {
        super.init(frame: frame)
        setupSubviews()
    }
    
    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
        setupSubviews()
    }
    
    // 布局子视图按钮
    private func setupSubviews() {
        addSubview(button)
        button.translatesAutoresizingMaskIntoConstraints = false
        NSLayoutConstraint.activate([
            button.centerXAnchor.constraint(equalTo: centerXAnchor),
            button.centerYAnchor.constraint(equalTo: centerYAnchor),
            button.widthAnchor.constraint(equalToConstant: 200),
            button.heightAnchor.constraint(equalToConstant: 50)
        ])
    }
}

// UITableViewController的代码

import UIKit

class MyTableViewController: UITableViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // 创建CustomView实例
        let customView = CustomView(frame: CGRect(x: 0, y: 0, width: tableView.frame.width, height: 100))
        
        // 将CustomView添加到tableView的某个cell上
        let indexPath = IndexPath(row: 0, section: 0) // 假设添加到第一个cell上
        let cell = tableView.cellForRow(at: indexPath)
        cell?.contentView.addSubview(customView)
    }
    
    // 其他UITableViewController的相关代码...
