TableView单元格、swipeactions和不同的序列Swift 4

// 创建TableView
let tableView = UITableView(frame: CGRect(x: 0, y: 0, width: 320, height: 480))
tableView.dataSource = self
tableView.delegate = self

// 注册单元格
tableView.register(UITableViewCell.self, forCellReuseIdentifier: "Cell")

// 实现数据源方法
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return data.count
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath)
    cell.textLabel?.text = data[indexPath.row]
    return cell
}

// 实现代理方法
func tableView(_ tableView: UITableView, leadingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
    let markAction = UIContextualAction(style: .normal, title: "标记") { (action, view, completionHandler) in
        // 执行标记操作
        completionHandler(true)
    }
    markAction.backgroundColor = .blue
    
    let configuration = UISwipeActionsConfiguration(actions: [markAction])
    return configuration
}

func tableView(_ tableView: UITableView, trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
    let deleteAction = UIContextualAction(style: .destructive, title: "删除") { (action, view, completionHandler) in
        // 执行删除操作
        completionHandler(true)
    }
    
    let configuration = UISwipeActionsConfiguration(actions: [deleteAction])
    return configuration
}

// 将TableView添加到视图中
view.addSubview(tableView)
