在UITableViewController中使用UIPickerView

class MyTableViewController: UITableViewController, UIPickerViewDelegate, UIPickerViewDataSource {
    // 类的实现代码
}

override func viewDidLoad() {
    super.viewDidLoad()
    
    let pickerView = UIPickerView()
    pickerView.delegate = self
    pickerView.dataSource = self
    
    // 设置pickerView的frame或约束，并添加到合适的位置
    // 例如：pickerView.frame = CGRect(x: 0, y: 0, width: 200, height: 200)
    // self.view.addSubview(pickerView)
}

func numberOfComponents(in pickerView: UIPickerView) -> Int {
    // 返回pickerView中的组件数
    return 1
}

func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
    // 返回指定组件中的行数
    return 5
}

func pickerView(_ pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {
    // 返回指定行和组件的标题
    return "Option \(row)"
}

func pickerView(_ pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {
    // 处理用户选择行的事件
    print("Selected option: \(row)")
}

override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath)
    
    let pickerView = UIPickerView()
    pickerView.delegate = self
    pickerView.dataSource = self
    
    // 设置pickerView的frame或约束，并将其添加到cell.contentView中
    // 例如：pickerView.frame = CGRect(x: 0, y: 0, width: 200, height: 200)
    // cell.contentView.addSubview(pickerView)
    
    return cell
}
