如何在IOS中创建一个选择器视图来选择几个日期

import UIKit

class ViewController: UIViewController {
    let datePicker = UIDatePicker()

    override func viewDidLoad() {
        super.viewDidLoad()
        
        // 设置日期选择器的模式为日期
        datePicker.datePickerMode = .date
        
        // 设置日期选择器的最小日期和最大日期
        let calendar = Calendar.current
        let currentDate = Date()
        let minDateComponents = calendar.dateComponents([.year], from: currentDate)
        let maxDateComponents = calendar.dateComponents([.year], from: currentDate.addingTimeInterval(365*24*60*60)) // 一年后的日期
        datePicker.minimumDate = calendar.date(from: minDateComponents)
        datePicker.maximumDate = calendar.date(from: maxDateComponents)
        
        // 设置日期选择器的默认日期
        datePicker.date = currentDate
        
        // 设置日期选择器的位置和大小
        datePicker.frame = CGRect(x: 0, y: 100, width: view.frame.width, height: 200)
        
        // 添加日期选择器到视图中
        view.addSubview(datePicker)
        
        // 添加日期选择器的ValueChanged事件
        datePicker.addTarget(self, action: #selector(datePickerValueChanged), for: .valueChanged)
    }
    
    @objc func datePickerValueChanged() {
        let selectedDate = datePicker.date
        // 处理选择的日期
        print(selectedDate)
    }
}
