swift3 - 每个月重复通知

Question

以下代码行可以每周重复一次本地通知，对吗？：

let triggerWeekly = Calendar.current.dateComponents([.weekday,hour,.minute,.second,], from: date)
let trigger = UNCalendarNotificationTrigger(dateMatching: triggerWeekly, repeats: true)

但是如何在每个月重复一次本地通知呢？安排每月通知需要哪些日期组件？

Answer 1

你可以这样使用：

let triggerMonthly = Calendar.current.dateComponents([.day], from: date)
let trigger = UNCalendarNotificationTrigger(dateMatching: triggerMonthly, repeats: true)
