从UILocalNotification迁移到UNUserNotification swift

Question

我正在迁移到NUUserNotification，但我遇到了一些问题，因为我正在学习较新的框架的通知，而我不知道较旧的框架。我希望这不是一些重复的东西，因为我读了很多关于如何迁移的帖子和教程，但还没有找到让我理解如何应用于这种情况的东西。我正在更新的代码不是我的，我花了一些时间去理解它。它是iOS Alarm ( https://github.com/natsu1211/Alarm-ios-swift)的克隆，我将它整合到我的应用程序中，以便在预定的时间/日期等执行操作。我很难理解的两件事是重复通知，据我所知，现在是每周一天或一次，对吗？fireDate参数已经折旧，那么我该如何重写它呢？：

private func minFireDateWithIndex(notifications: [UILocalNotification]) -> (Date, Int)? {
    if notifications.isEmpty {
        return nil
    }
    var minIndex = -1
    var minDate: Date = notifications.first!.fireDate!
    for n in notifications {
        let index = n.userInfo!["index"] as! Int
        if(n.fireDate! <= minDate) {
            minDate = n.fireDate!
            minIndex = index
        }
    }
    return (minDate, minIndex)
}

我在更新时遇到问题的另一个代码是检查现有的通知，这些通知现在是getPendingNotificationRequestsWithCompletionHandler:]。它是旧函数中定义通知的if let n = UIApplication.shared.scheduledLocalNotifications，我想我已经为剩下的部分更新了它。旧代码：

func setupNotificationSettings() -> UIUserNotificationSettings {

        var snoozeEnabled: Bool = false

        if let n = UIApplication.shared.scheduledLocalNotifications {
            if let result = minFireDateWithIndex(notifications: n) {
                let i = result.1
                snoozeEnabled = alarmModel.alarms[i].snoozeEnabled
            }
        }

        // Specify the notification types.

        let notificationTypes: UIUserNotificationType = [UIUserNotificationType.alert, UIUserNotificationType.sound]
        // Specify the notification actions.
        let stopAction = UIMutableUserNotificationAction()
        stopAction.identifier = Id.stopIdentifier
        stopAction.title = "OK"

        stopAction.activationMode = UIUserNotificationActivationMode.background    // choose activation mode for app on tapping notification

        stopAction.isDestructive = false
        stopAction.isAuthenticationRequired = false

        let snoozeAction = UIMutableUserNotificationAction()
        snoozeAction.identifier = Id.snoozeIdentifier
        snoozeAction.title = "Snooze"
        snoozeAction.activationMode = UIUserNotificationActivationMode.background
        snoozeAction.isDestructive = false
        snoozeAction.isAuthenticationRequired = false

        let actionsArray = snoozeEnabled ? [UIUserNotificationAction](arrayLiteral: snoozeAction, stopAction) : [UIUserNotificationAction](arrayLiteral: stopAction)
        let actionsArrayMinimal = snoozeEnabled ? [UIUserNotificationAction](arrayLiteral: snoozeAction, stopAction) : [UIUserNotificationAction](arrayLiteral: stopAction)
        // Specify the category related to the above actions.
        let alarmCategory = UIMutableUserNotificationCategory()
        alarmCategory.identifier = "myAlarmCategory"
        alarmCategory.setActions(actionsArray, for: .default)
        alarmCategory.setActions(actionsArrayMinimal, for: .minimal)


        let categoriesForSettings = Set(arrayLiteral: alarmCategory)
        // Register the notification settings.
        let newNotificationSettings = UIUserNotificationSettings(types: notificationTypes, categories: categoriesForSettings)
        UIApplication.shared.registerUserNotificationSettings(newNotificationSettings)
        return newNotificationSettings
    }

新代码编辑：

    func setRouteNotification(_ date: Date, onWeekdaysForNotify weekdays:[Int], snoozeEnabled:Bool,  onSnooze: Bool, soundName: String, routeName: String, index: Int) {
    // Notification content
    let routeCheckNotificationContent = UNMutableNotificationContent()
    let datesForNotification = correctDate(date, onWeekdaysForNotify: weekdays)
    routeCheckNotificationContent.title = "Hello!! Are you ready to cycle?"
    routeCheckNotificationContent.body = "Check route for alerts?"
    routeCheckNotificationContent.categoryIdentifier = Id.notificationCategory
    routeCheckNotificationContent.sound = UNNotificationSound.init(named: soundName + ".mp3") // check for the + ".mp3"

    // Define actions
    let check = UNNotificationAction(identifier: Id.checkActionIdentifier, title: " Check", options: [.foreground])
    let wait = UNNotificationAction(identifier: Id.waitActionIdentifier, title: "Wait", options: [])
    // Define category
    let routeCategory = UNNotificationCategory(identifier: Id.notificationCategory, actions: [check, wait], intentIdentifiers: [], options: [])
    // Register category
    UNUserNotificationCenter.current().setNotificationCategories([routeCategory])


    let repeating: Bool = !weekdays.isEmpty
    routeCheckNotificationContent.userInfo = ["snooze" : snoozeEnabled, "index": index, "soundName": soundName, "routeName": routeName, "repeating" : repeating]
    //repeat weekly if repeat weekdays are selected
    //no repeat with snooze notification
    if !weekdays.isEmpty && !onSnooze{
    }

    syncAlarmModel()
    for d in datesForNotification {
        if onSnooze {
            alarmModel.alarms[index].date = Scheduler.correctSecondComponent(date: alarmModel.alarms[index].date)
        }
        else {
            alarmModel.alarms[index].date = d
        }
        // Notification trigger

        let calendar = Calendar(identifier: .gregorian)


        let components = calendar.dateComponents(in: .current, from: d)
        let newComponents = DateComponents(calendar: calendar, timeZone: .current, month: components.month, day: components.day, hour: components.hour, minute: components.minute, second: components.second, weekday: components.weekday)
        let trigger = UNCalendarNotificationTrigger(dateMatching: newComponents, repeats: true)
        // Notification Request
        let routeNotificationRequest = UNNotificationRequest(identifier: "routeNotificationRequest", content: routeCheckNotificationContent, trigger: trigger)

        // Add request
        UNUserNotificationCenter.current().add(routeNotificationRequest) { (Error) in
            if Error != nil {
                print("something went wrong with adding notification")
            }
        }
    }
}

var weekdays: [Int]!是在WeekdaysViewController (一个TableViewController )中填充的数组，用于选择行。

现在，当我选择任何一天时，通知都不会触发。

@Mikael。@甜心。在代码中挣扎了一下之后，因为我认为我只能使用.weekday组件来设置重复，所以我发现我可以使用与将所选日期存储到数组中一样的逻辑来使用date设置每天的重复通知，所以我确实设置了一个for in循环来为每个存储的日期设置一个具有唯一标识符的新通知。最终的代码是：

        func setRouteNotification(_ date: Date, onWeekdaysForNotify weekdays:[Int], snoozeEnabled:Bool,  onSnooze: Bool, soundName: String, routeName: String, index: Int) {
            // Notification content
            let routeCheckNotificationContent = UNMutableNotificationContent()
            let datesForNotification = correctDate(date, onWeekdaysForNotify: weekdays)
            routeCheckNotificationContent.title = "Hello!! Are you ready to cycle?"
            routeCheckNotificationContent.body = "Check route for alerts?"
            routeCheckNotificationContent.categoryIdentifier = Id.notificationCategory
            routeCheckNotificationContent.sound = UNNotificationSound.init(named: soundName + ".mp3") // check for the + ".mp3"

            // Define actions
            let check = UNNotificationAction(identifier: Id.checkActionIdentifier, title: " Check", options: [.foreground])
            let wait = UNNotificationAction(identifier: Id.waitActionIdentifier, title: "Wait", options: [])
            // Define category
            let routeCategory = UNNotificationCategory(identifier: Id.notificationCategory, actions: [check, wait], intentIdentifiers: [], options: [])
            // Register category
            UNUserNotificationCenter.current().setNotificationCategories([routeCategory])


            let repeating: Bool = !weekdays.isEmpty
            routeCheckNotificationContent.userInfo = ["snooze" : snoozeEnabled, "index": index, "soundName": soundName, "routeName": routeName, "repeating" : repeating]
            //repeat weekly if repeat weekdays are selected
            //no repeat with snooze notification
            if !weekdays.isEmpty && !onSnooze{
            }

            syncAlarmModel()
            var counter = 0

            for d in datesForNotification {
                if onSnooze {
                    alarmModel.alarms[index].date = Scheduler.correctSecondComponent(date: alarmModel.alarms[index].date)
                }
                else {
                    alarmModel.alarms[index].date = d
                }
                // Notification trigger

                let calendar = Calendar(identifier: .gregorian)


                let components = calendar.dateComponents(in: .current, from: d)
                var newComponents = DateComponents(calendar: calendar, timeZone: .current, month: components.month, day: components.day, hour: components.hour, minute: components.minute, second: components.second, weekday: components.weekday)
                newComponents.weekday = weekdays[counter]
                let trigger = UNCalendarNotificationTrigger(dateMatching: newComponents, repeats: true)
                // Notification Request
//                let trigger = UNCalendarNotificationTrigger(dateMatching: components, repeats: true)
                let routeNotificationRequest = UNNotificationRequest(identifier: "routeNotificationRequest\(counter)", content: routeCheckNotificationContent, trigger: trigger)

                // Add request
                UNUserNotificationCenter.current().add(routeNotificationRequest) { (Error) in
                    if Error != nil {
                        print("something went wrong with adding notification")
                    }
                }
                print("added request\(counter)")
                counter = ( counter + 1 )

            }
            print(alarmModel.alarms)
        }

如果我理解正确的话，您希望有一个重复的本地通知。如果是这样，您只需使用以下命令设置通知

let dateInfo = Calendar.current.dateComponents([.weekday,.hour,.minute], from: aDateWithTheDayHourAndMinuteYouWantToTriggerTheNotification)
let trigger = UNCalendarNotificationTrigger(dateMatching: dateInfo, repeats: true)
let request = UNNotificationRequest(identifier: identifier, content: content, trigger: trigger)
