Question

我正在为类似警报的应用程序将通知更新到 UNUserNotification 框架，我以为我成功了，但是我意识到当我设置多个警报时，我只会收到最新的警报。重复的日子正在使面团。可能是触发器标识符与先前的字符串相同并被覆盖的问题？我真的不了解这种行为，也找不到问题所在。

这是代码：

func setRouteNotification(_ date: Date, onWeekdaysForNotify weekdays:[Int], snoozeEnabled:Bool,  onSnooze: Bool, soundName: String, routeName: String, index: Int) {
    configureCategory()
    // 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")

    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 = 1

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

        // Notification Request
        let routeNotificationRequest = UNNotificationRequest(identifier: "routeNotificationRequest\(scheduledNotifications.count + 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\(alarmModel.alarms.count + weekdays.count + counter)")
        scheduledNotifications.append(counter)
        print("scheduled notifications are \(scheduledNotifications.count)")
        counter = ( counter + 1 )
    }
    print(alarmModel.alarms)
}

为什么不设置所有已编程的通知？像往常一样非常感谢您。

编辑：

我尝试设置一个数组var scheduledNotifications: [Int] = []，该数组在添加通知时存储一个渐进数字，并将其用作请求的标识符

let routeNotificationRequest = UNNotificationRequest(identifier: "routeNotificationRequest\(scheduledNotifications.count + counter)", content: routeCheckNotificationContent, trigger: trigger)

因此，我确定所有添加的通知都具有唯一的请求标识符，但是没有任何变化，仍然仅收到最新的通知。

我使用以秒为单位的当前日期作为标识符，它对我的工作如下：

override func viewDidAppear(_ animated: Bool) {
    super.viewDidAppear(animated)

    UNUserNotificationCenter.current().requestAuthorization(options: []) { (granted, error) in


        if granted {

            let routeCheckNotificationContent = UNMutableNotificationContent()
            routeCheckNotificationContent.title = "Hello!! Are you ready to cycle?"
            routeCheckNotificationContent.body = "Check route for alerts?"
            routeCheckNotificationContent.categoryIdentifier = "\(Date().timeIntervalSince1970)"
            routeCheckNotificationContent.sound = UNNotificationSound.default()

            routeCheckNotificationContent.userInfo = ["snooze" : false, "index": 1, "soundName": "1", "routeName": "hmm", "repeating" : true]


            self.addNotification(content: routeCheckNotificationContent, date: Date().addingTimeInterval(30))
            self.addNotification(content: routeCheckNotificationContent, date: Date().addingTimeInterval(60))

        } else {

            print("Notification permission dendied !!")
        }
    }
}

func addNotification(content: UNMutableNotificationContent, date: Date) {

    let calendar = Calendar(identifier: .gregorian)

    let components = calendar.dateComponents(in: .current, from: date)
    let newComponents = DateComponents(calendar: calendar, timeZone: .current, month: components.month, day: components.day, hour: components.hour, minute: components.minute, second: components.second)

    let trigger = UNCalendarNotificationTrigger(dateMatching: newComponents, repeats: true)
    // Notification Request
    let routeNotificationRequest = UNNotificationRequest(identifier: "\(date.timeIntervalSince1970)", content: content, trigger: trigger)


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

也许您的约会有问题！

尝试不同的方法后，我想我解决了它，但是我不明白为什么它不能像我做事的方式那样起作用。 d是从setRouteNotification函数中的for in循环获取的Date值，它表示要安排的通知的工作日（请参阅问题代码）工作：

let components2 = Calendar.current.dateComponents([.weekday,.hour,.minute,.second,], from: d)
let trigger2 = UNCalendarNotificationTrigger(dateMatching: components2, repeats: true)

不起作用：

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

我遇到了同样的问题，并意识到它正在发生，因为我对多个通知使用了相同的标识符@“ ID”。当我使标识符唯一时，它们都会被触发。

UNNotificationRequest *request = [UNNotificationRequest requestWithIdentifier:@"ID" content:notification trigger:trigger];

仅最后添加的通知被触发
