如何在swift中安排相同的本地通知 [英] How to schedule a same local notification in swift

问题描述

我只想在Swift中安排相同的本地通知。例如，我只想安排一条消息，说现在是时候计算本月的账单了，我想在下个月再次发送同样的消息。

I just want to schedule a same local notification in Swift. For example I just want to schedule a message saying "It's time to calculate your bill for this month" and I want to send this same message again next month.

如何在Swift中进行这种本地通知？

推荐答案

UILocalNotification 有一个 repeatInterval 属性，可让您指定方式通常应该重复通知。请注意，这是 NSCalendarUnit ，而不仅仅是一个任意数字，因此您只能在每个日历单位（第二，分钟，小时，日，周，月）重复通知一次等）。请参阅 NSCalendarUnit 文档了解更多选项。

UILocalNotification has a repeatInterval property that lets you specify how often the notification should repeat. Note that this is an NSCalendarUnit, not just an arbitrary number, so you can only make a notification repeat once per calendar unit (second, minute, hour, day, week, month, etc.). See the NSCalendarUnit documentation for more options.

例如，您可以每月重复通知：

For example, you can make a notification repeat every month with:

notification.repeatInterval = .CalendarUnitMonth
