swift - UILocalNotification 不触发 iOS 8.4

Question

Printing description of localNotification:

{fire date = Wednesday, August 5, 2015 at 9:00:00 AM India Standard Time, time zone = (null), repeat interval = NSCalendarUnitDay, repeat count = UILocalNotificationInfiniteRepeatCount, next fire date = Thursday, August 6, 2015 at 9:00:00 AM India Standard Time, user info = (null)}

如您所见，时间是上午 9:00:00，但我正在做的事情从来没有在这里触发

• 我正在通过更改我的 Mac 时间在模拟器上进行测试，是这样吗？
• 我也厌倦了将我的 mac 时间更改为下一个开火日期，但仍然无法正常工作。
• 这些能否在 Live 设备中完美运行？

更新代码

 var calendar = NSCalendar.currentCalendar()
      //  calendar.timeZone = NSTimeZone(forSecondsFromGMT: 0)
        let comp = NSDateComponents()
        //comp.timeZone = NSTimeZone(forSecondsFromGMT: 0)
        comp.day = NSDate().day()
        comp.month = NSDate().month()
        comp.year = NSDate().year()


        comp.hour = date.hour()
        comp.minute = date.minute()
        var grouptimestamp = calendar.dateFromComponents(comp)?.getCurrentTimeStemp()

        var minutes = self.getMinutestFromTimestemp(NSDate.getCurrentTimeStemp() - grouptimestamp!)

        if minutes > 59 {
            println("Missed")
        }else if minutes < -5 {
            println("Early")
        }else{
            println("Takenow")
        }

        UIApplication.sharedApplication().cancelAllLocalNotifications()
        var localNotification:UILocalNotification = UILocalNotification()
        localNotification.alertAction = "Myplan"
        localNotification.alertBody = "Woww it works!!"
        localNotification.fireDate = NSDate(timeIntervalSince1970: NSTimeInterval(grouptimestamp!))
        localNotification.repeatInterval = NSCalendarUnit.CalendarUnitDay
        UIApplication.sharedApplication().scheduleLocalNotification(localNotification)

Answer 1

这是因为您没有将timezone设置为系统时区。默认情况下，它根据您的位置而不是根据系统时间设置时区。尝试将此添加到您的代码中:

    notification.timeZone = NSTimeZone.systemTimeZone()

这会将您的通知时区更改为系统时区，然后如果您更改时间，通知将启动。

希望这有帮助:)
