设置特定日期和时间的本地通知swift 3

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 am 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。
