【中文标题】如何根据 CVcalendar 中的特定时间进行每日本地通知？

【英文标题】：how to make daily local notification depending on specific time in CVcalendar?

【问题描述】：

我正在使用 cvcalendar 并且每天都有不同的时间用于 fajer、dohor、aser、maghreb、ishaa。例如，我为 Fajer 选择了 Adan，所以我想每天都得到 adan，而且每天都有不同的时间。因此，当我在 DidreceivedLocalNotification 中收到通知时，我想在日历中转到第二天并获取第二天的时间，知道从 CoreData 获取时间。

在视图中会出现

        let date = NSDate()
        let dateFormatter = NSDateFormatter()

        dateFormatter.dateFormat = "dd-MM-yyyy"
        let calendar = NSCalendar.currentCalendar()
        let calendarForDate = NSCalendar.currentCalendar()
        let componentsForDate = calendar.components([.Day , .Month , .Year], fromDate: date)

        let year =  componentsForDate.year
        let month = componentsForDate.month
        let day = componentsForDate.day
        //////////
        //// Conditions after selecting the user (vibration, beep, Adan ) these conditions are testing the selected choice to send a notification to the user on his choice
        //



        if prayerCommingFromAdan.id == 0 && prayerCommingFromAdan.ringToneId != 0

            notificationId.id = 0
            let hours = prayer0.time[0...1]
            let minutes = prayer0.time[3...4]
            let fajerTime = "\(month)-\(day)-\(year) \(hours):\(minutes)"
            var dateFormatter = NSDateFormatter()
            dateFormatter.dateFormat = "MM-dd-yyyy hh:mm"
            dateFormatter.timeZone = NSTimeZone.localTimeZone()

            // convert string into date
            let dateValue = dateFormatter.dateFromString(fajerTime) as NSDate!





            var dateComparisionResult:NSComparisonResult = NSDate().compare(dateValue)

            if dateComparisionResult == NSComparisonResult.OrderedAscending
            
                addNotificationAlarm(year, month: month, day: day, hour: prayer0.time[0...1], minutes: prayer0.time[3...4], soundId: prayerCommingFromAdan.ringToneId, notificationBody: "It is al fajr adan")

            

AppDelegate中的DidreceivedLocalNotification应该怎么做？

【参考方案1】：

您可以使用此代码根据时间安排每日通知。

 func ScheduleMorning() 
        let calendar: NSCalendar = NSCalendar(calendarIdentifier: NSCalendarIdentifierGregorian)!
        var dateFire=NSDate()

        var fireComponents = calendar.components([.Hour, .Minute, .Second], fromDate: dateFire)


        if (fireComponents.hour >= 7) 
            dateFire=dateFire.dateByAddingTimeInterval(86400)  // Use tomorrow's date

            fireComponents = calendar.components([.Hour, .Minute, .Second], fromDate: dateFire)

        


        fireComponents.hour = 7
        fireComponents.minute = 0
        fireComponents.second = 0

        // Here is the fire time you can change as per your requirement
        dateFire = calendar.dateFromComponents(fireComponents)!

        let localNotification = UILocalNotification()
        localNotification.fireDate = dateFire // Pass your Date here
        localNotification.alertBody = "Your Message here."
        localNotification.userInfo = ["CustomField1": "w00t"]
        localNotification.repeatInterval = NSCalendarUnit.Day

        UIApplication.sharedApplication().scheduleLocalNotification(localNotification)    

用于接收

 func application(application: UIApplication, didReceiveLocalNotification notification: UILocalNotification) 
        // Do something serious in a real app.
        print("Received Local Notification:")
        print(notification.userInfo)
    

【讨论】：

Anand 谢谢，但我的问题是如何在日历中获取第二天的时间以及如何在 AppDelegate 中使用 DidreceivedLocalNotification ？

我在答案中添加了接收代码。请检查一下。

您可以使用 NSDate 手动设置时间来设置本地通知。

Anand ，日历中每天有 5 个不同的时间，我们使用 API 来获取这些时间一年。所以不能手动设置它们。我只需要如何访问第二天的时间以每天设置自动通知。

您可以根据需要更改此代码，我在这里为您提供如何做这件事的方法。
