xcode11如何在PickerView中给选定的选项一个动作。这样，当我在所选数组中选择一个选项时，就可以对其执行操作

import UIKit

class ViewController: UIViewController, UIPickerViewDelegate, UIPickerViewDataSource {
    
    let options = ["Option 1", "Option 2", "Option 3"] // 所选数组
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        let pickerView = UIPickerView()
        pickerView.delegate = self
        pickerView.dataSource = self
        view.addSubview(pickerView)
    }
    
    // 实现UIPickerViewDataSource协议中的方法
    func numberOfComponents(in pickerView: UIPickerView) -> Int {
        return 1 // 单列选择器
    }
    
    func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
        return options.count // 返回所选数组的元素个数
    }
    
    // 实现UIPickerViewDelegate协议中的方法
    func pickerView(_ pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {
        return options[row] // 返回所选数组中对应行的选项
    }
    
    func pickerView(_ pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {
        let selectedOption = options[row] // 获取选定的选项
        // 执行对选定选项的操作
        print("选定的选项是：\(selectedOption)")
    }
}
