设置特定日期和时间的本地通知swift 3

Question

在我的应用程序中,我想添加本地通知.方案是用户可以选择从周一到周日的任何时间和日期.例如,如果用户选择Mon,Thur和Sat作为日期和时间为晚上11:00,那么现在应该在所有选定的日期和特定时间通知用户.

码:

 let notification = UNMutableNotificationContent()
 notification.title = "Danger Will Robinson"
 notification.subtitle = "Something This Way Comes"
 notification.body = "I need to tell you something, but first read this."

 let notificationTrigger = UNTimeIntervalNotificationTrigger(timeInterval: 60, repeats: true)
 // let test = UNCalendarNotificationTrigger()
 let request = UNNotificationRequest(identifier: "notification1", content: notification, trigger: notificationTrigger)
 UNUserNotificationCenter.current().add(request, withCompletionHandler: nil)

我正在使用此代码,但这不符合我的需要.

要获取在特定时间某个工作日重复的本地通知,您可以使用UNCalendarNotificationTrigger:

let notification = UNMutableNotificationContent()
notification.title = "Danger Will Robinson"
notification.subtitle = "Something This Way Comes"
notification.body = "I need to tell you something, but first read this."

// add notification for Mondays at 11:00 a.m.
var dateComponents = DateComponents()
dateComponents.weekday = 2
dateComponents.hour = 11
dateComponents.minute = 0
let notificationTrigger = UNCalendarNotificationTrigger(dateMatching: dateComponents, repeats: true)

let request = UNNotificationRequest(identifier: "notification1", content: notification, trigger: notificationTrigger)
UNUserNotificationCenter.current().add(request, withCompletionHandler: nil)

如果您想在星期一,星期四和星期六11:00收到通知,则需要添加3个单独的请求.为了能够删除它们,您必须跟踪标识符.
