每周应用程序都会通知消息“Hello Message”

Answer 1

Swift 2.2：

添加：

localNotification.repeatInterval = .Weekday

Swift 3.0：

    let content: UNMutableNotificationContent = UNMutableNotificationContent()

    content.title = "Title"

    content.subtitle = "Subtitle"

    content.body = "Hello Message"

    let calendar = Calendar.current

    let alarmTime = Date().addingTimeInterval(60*60*24*7)
    let alarmTimeComponents = calendar.dateComponents([.weekday], from: alarmTime)

    let trigger = UNCalendarNotificationTrigger(dateMatching: alarmTimeComponents, repeats: true)

    let request = UNNotificationRequest(identifier: workoutAlarmIdentifier,
                                        content: content,
                                        trigger: trigger)

    UNUserNotificationCenter.current().add(request)
    {
        (error) in // ...
    }

Answer 2

现在是11月5日星期六下午2点
我的选择器设置为11月5日星期六下午2:10
本地通知将于11月5日星期六下午2:10显示

通知将于11月12日星期六下午2:10继续通知

    let ok = UNNotificationAction(identifier: "OKIdentifier", title: "Open", options: [.foreground])
    let cancel = UNNotificationAction(identifier: "CancelIdentifier", title: "Dismiss", options: [])
    let category = UNNotificationCategory(identifier: "message", actions: [ok, cancel], intentIdentifiers: [], options: [])
    UNUserNotificationCenter.current().setNotificationCategories([category])

    let content = UNMutableNotificationContent()
    content.body = "open the SAMPLE app"
    content.categoryIdentifier = "message"

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

    let request = UNNotificationRequest(identifier:"five second", content: content, trigger: trigger)
    UNUserNotificationCenter.current().add(request){(error) in
        if (error != nil){
            //handle here
            print("error : \(error)"  )
        }
    }
