将更新后的数组数据传递给uipickerview

import UIKit

class ViewController: UIViewController, UIPickerViewDataSource, UIPickerViewDelegate {
    
    @IBOutlet weak var pickerView: UIPickerView!
    
    var dataArray: [String] = ["Option 1", "Option 2", "Option 3"]
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        pickerView.dataSource = self
        pickerView.delegate = self
    }
    
    // MARK: - UIPickerViewDataSource
    
    func numberOfComponents(in pickerView: UIPickerView) -> Int {
        return 1 // 返回组件数为1
    }
    
    func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
        return dataArray.count // 返回数组数据的行数
    }
    
    // MARK: - UIPickerViewDelegate
    
    func pickerView(_ pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {
        return dataArray[row] // 返回每行显示的内容
    }
    
    func pickerView(_ pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {
        let selectedOption = dataArray[row] // 获取用户选择的选项
        print("Selected option: \(selectedOption)")
    }
    
    // 更新数组数据的方法
    func updateDataArray(with newData: [String]) {
        dataArray = newData
        pickerView.reloadAllComponents() // 重新加载数据
    }
