您好，我想知道是否有办法在特定日期通过用户的批准显示推送通知。我目前有一个推送通知的切换，当调用此切换时，它应该显示一个选择器视图，以便用户希望这些通知何时到来。例如，用户可以选择每周，每天，每月（这将是非常好的）或每年的通知。此外，让用户能够选择具体的日子将是一个很好的接触。我不知道如何做到这一点。在此过程中，我将不胜感激任何指导或帮助。
背景： 我正在为我的高中报纸制作一个应用程序，并想提醒用户查看该应用程序。每个月的第一天通知用户会很好，因为我们的学校会在每个月的第一天发布新问题。
以下是我的应用现在的screenshot。
这是我当前的AppDelegate.swift代码以供参考：
