UITableView中的Swift自动布局标题视图[已解决]

class CustomHeaderView: UIView {
    let titleLabel = UILabel()
    
    override init(frame: CGRect) {
        super.init(frame: frame)
        
        // 添加标题标签
        addSubview(titleLabel)
        
        // 设置标题标签的布局约束
        titleLabel.translatesAutoresizingMaskIntoConstraints = false
        titleLabel.topAnchor.constraint(equalTo: topAnchor, constant: 8).isActive = true
        titleLabel.leadingAnchor.constraint(equalTo: leadingAnchor, constant: 16).isActive = true
        titleLabel.trailingAnchor.constraint(equalTo: trailingAnchor, constant: -16).isActive = true
        titleLabel.bottomAnchor.constraint(equalTo: bottomAnchor, constant: -8).isActive = true
        
        // 设置标题标签的样式
        titleLabel.font = UIFont.boldSystemFont(ofSize: 16)
        titleLabel.textColor = UIColor.black
    }
    
    required init?(coder aDecoder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }
}

class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
    let tableView = UITableView()
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // 设置UITableView的代理和数据源
        tableView.delegate = self
        tableView.dataSource = self
        
        // 注册自定义的标题视图
        tableView.register(CustomHeaderView.self, forHeaderFooterViewReuseIdentifier: "CustomHeaderView")
        
        // 其他设置...
    }
    
    // UITableViewDataSource代理方法
    func numberOfSections(in tableView: UITableView) -> Int {
        return 1
    }
    
    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return 10
    }
    
    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath)
        // 配置cell的内容...
        return cell
    }
    
    // UITableViewDelegate代理方法
    func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
        let headerView = tableView.dequeueReusableHeaderFooterView(withIdentifier: "CustomHeaderView") as? CustomHeaderView
        headerView?.titleLabel.text = "Section \(section + 1)"
        return headerView
    }
    
    func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
        return 40
    }
