Question

我在应用程序中使用本地通知时遇到问题。

我正在使用自定义内容安排本地通知＆amp;自定义操作类别。这是安排＆amp;在iOS 11中触发，但在iOS 10中没有触发。

根据文档，它也应该在iOS 10中工作。

请查看我的代码，并告诉我为什么它不能在这种特定情况下工作。

代码如下。

AppDelegate.swift

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {

    .......

    if #available(iOS 10.0, *) {
        UNUserNotificationCenter.current().delegate = self
    }
    .......

    return true
}

func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {

    completionHandler([.alert, .sound, .badge])
}

func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {

    print("Local Notification :: ", response)
}

自定义操作代码

func configureNotificationCenter() {

    let actionRemindAgain = UNNotificationAction(identifier: NTConstants.LocalNotification.action.remindMeAgain, title: "Remind me Again!⏰", options: [.authenticationRequired])
    let actionViewDetails = UNNotificationAction(identifier: NTConstants.LocalNotification.action.viewDetails, title: "View Details!", options: [.foreground])
    let actionClose = UNNotificationAction(identifier: NTConstants.LocalNotification.action.dismiss, title: "Dismiss", options: [])

    //Event Category
    let eventCategory = UNNotificationCategory(identifier: NTConstants.LocalNotification.category.reminder, actions: [actionRemindAgain, actionViewDetails, actionClose], intentIdentifiers: [], options: [])

    //Register Category
    UNUserNotificationCenter.current().setNotificationCategories([eventCategory])
}

日程安排代码

func scheduleLocalNotification() {

    self.configureNotificationCenter()

    //Local Notification
    let content = UNMutableNotificationContent()
    content.title = notifyTitle
    content.subtitle = notifySubTitle
    content.body = notifyDesc

    //Category
    content.categoryIdentifier = "reminder"

    //Trigger
    let scheduleDate = Date(timeIntervalSince1970: TimeInterval(scheduleTimeInterval / 1000)) //My Schedule Data
    let triggerDate = Calendar.current.date(byAdding: .hour, value: -2, to: scheduleDate) // Should be call before 2 hours
    let dateComponents = Calendar.current.dateComponents([.year, .month, .day, .hour, .minute], from: triggerDate!)

    let trigger = UNCalendarNotificationTrigger(dateMatching: dateComponents, repeats: false)

    //Request
    let request = UNNotificationRequest(identifier: "notification_\((notifyId))", content: content, trigger: trigger)

    //Add Request
    UNUserNotificationCenter.current().add(request) { (error) in
        if let error = error {
            NTPrint("Unable to add notification : \(error.localizedDescription)")
        }
        else {
            NTPrint("Scheduled :: ", request.identifier)
        }
    }
}

此代码成功运作＆amp;安排本地通知。结果如下：

<UNNotificationRequest: 0x18d65360; 

identifier: notification_111, 

content: <UNNotificationContent: 0x18daead0; 

    title: Event..!!, 
    subtitle: 31 Mar at 2:00 PM to 01 Apr at 12:00 PM, 
    body: , 
    categoryIdentifier: reminder, 
    launchImageName: , 
    peopleIdentifiers: (), 
    threadIdentifier: , 
    attachments: (), 
    badge: (null), 
    sound: (null), 
    hasDefaultAction: YES, 
    defaultActionTitle: (null), 
    shouldAddToNotificationsList: YES, 
    shouldAlwaysAlertWhileAppIsForeground: NO, 
    shouldLockDevice: NO, 
    shouldPauseMedia: NO, 
    isSnoozeable: NO, 
    fromSnooze: NO, 
    darwinNotificationName: (null), 
    darwinSnoozedNotificationName: (null), 

    trigger: <UNCalendarNotificationTrigger: 0x18d51470; 
        dateComponents: <NSDateComponents: 0x18da3320>
        Calendar Year: 2018
        Month: 3
        Leap month: no
        Day: 31
        Hour: 12
        Minute: 00, 
    repeats: NO
>>

正如我在2小时之前设定的那样，它在12点正确设置它在iOS 11设备中运行良好。但不适用于iOS 10 更新的代码有什么问题吗？或者其他任何事情都需要处理。

请告诉我有关解决方案的信息提前谢谢。

Answer 1

生成本地通知。
Content.body 不得为null或空白

如果在将空白解析为正文时，iOS 10将不会生成本地推送。但它在iOS 11中运行。

Content.body 的价值是关键问题。
