Ios 特定时间的消防警报-Swift

您好，我想知道是否有一种方法可以显示推送通知，并在特定日期获得用户的批准。我目前有一个推送通知的切换，当这个切换被调用时，它应该显示一个选择器视图，以便用户希望这些通知何时出现。例如，用户可以选择每周、每天、每月（这非常好）或每年发送通知。此外，让用户能够选择具体的日期也是一个不错的选择。我不知道我怎样才能做到这一点。我希望在整个过程中得到任何指导或帮助

背景：我正在为我高中的报纸制作一个应用程序，希望提醒用户查看该应用程序。在每个月的第一天通知用户会很好，因为我们学校在每个月的第一天发布一个新版本

以下是我的应用程序现在的外观

以下是我当前的AppDelegate.swift代码，以供参考：
