如何为自定义XIB单元添加操作按钮？

我想创建一个带有动作按钮的自定义XIB表视图单元格，该按钮可以设置到新的视图控制器。

到目前为止，我已经创建了一个带有按钮（timeButton）的自定义XIB单元格（TaskListCell ），并将TaskListCell注册到TaskListViewController。对于tableView（_：cellForRowAt :)，我为timeButton添加了标签，并添加了addTarget （_：action：for :)以在点击timeButton时做出响应。但是，我收到此错误消息：线程1：“-[[Sprints.TaskListCellPressedTimeButton：]：无法识别的选择器已发送到实例0x105311560”

这是定制的XIB单元文件：

class TaskListCell: UITableViewCell {

    @IBOutlet weak var nameField: UITextField!
    @IBOutlet weak var timeButton: UIButton!
    
    @IBAction func pressedTimeButton(_ sender: UIButton) {
    }
    
    override func awakeFromNib() {
    }
    override func setSelected(_ selected: Bool, animated: Bool) {
    }
}

这是在表视图中显示自定义单元格的ViewController：

class TaskListViewController: UIViewController {
    
    // MARK: - Outlet Variables
    @IBOutlet weak var taskList: SelfSizedTableView!
    ...
    
    // MARK: - Instance Variables
    var taskData = [TaskData]()
    var taskCount: Int = 1
    ...
    
    // MARK: - View Controller Methods
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // Register TaskListCell.xib file
        let taskCellNib = UINib(nibName: "TaskCell", bundle: nil)
        taskList.register(taskCellNib, forCellReuseIdentifier: "taskCell")
        ...
        
        // Connect table view's dataSource and delegate to current view controller
        taskList.delegate = self
        taskList.dataSource = self
    }
    
    // MARK: - Action Methods
    // Adds new cell in Table View
    @IBAction func pressedAddTask(_ sender: UIButton) {
        taskCount += 1
        taskList.reloadData()
        taskList.scrollToRow(at: IndexPath(row: taskCount-1, section: 0), at: .bottom, animated: true)
    }
    
    // MARK: - Methods
    // Segues to SelectTime screen when timeButton is pressed
    @objc func pressedTimeButton(_ sender: UIButton) {
        let destination = SelectTimeViewController()
        navigationController?.pushViewController(destination, animated: true)
    }
    
}

extension TaskListViewController: UITableViewDataSource {
    
    // Return the number of rows in table view
    func tableView(_ tableView: UITableView,
                   numberOfRowsInSection section: Int) -> Int {
        return taskCount
    }
    
    // Return the cell to insert in table view
    func tableView(_ tableView: UITableView,
                   cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        
        let cell = tableView.dequeueReusableCell(withIdentifier: "taskCell", for: indexPath) as! TaskListCell

        // Fatal error for next line: "Unexpectedly found nil while implicitly unwrapping an Optional value"
        cell.timeButton.tag = indexPath.row
        cell.timeButton.addTarget(self, action: #selector(pressedTimeButton(_:)), for: .touchUpInside)
        
        return cell
    }
    
}

extension TaskListViewController: UITableViewDelegate {
}
