迅速设置特定日期和时间的本地通知3

Question

在我的应用程序中，我想添加本地通知。该场景将是用户可以选择从Mon到Sun的任何时间和日期。例如，如果用户选择星期一，星期四和星期六为下午11点的日期和时间，那么现在应在所有选定日期和特定时间通知用户。

代码：

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) 

我使用此代码，但这并不根据我所需要的工作。

要获得在某个时间在某个工作日的重复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11:00在周一，周四和周六通知您需要添加3分开请求。为了能够删除它们，你必须跟踪标识符。
