swift - 徽章图标未更新

Question

我在 Appedelegate 的“DidfininshLaunchingWithOptions”下添加了此代码，希望它每天都能更改徽章图标编号。有人知道我如何重写它才能真正起作用吗？

 let timer = NSTimer.scheduledTimerWithTimeInterval(864000, target: self, selector: "sendNotification:", userInfo: nil, repeats: true)

    func sendNotification(timer: NSTimer) {

        let localNotification:UILocalNotification = UILocalNotification()
        localNotification.fireDate = NSDate(timeIntervalSinceNow: 3)
        localNotification.alertBody = nil;
        localNotification.alertAction = nil;
        localNotification.timeZone = NSTimeZone.defaultTimeZone()
        localNotification.repeatInterval = NSCalendarUnit.Day

        //Add one to the icon badge number

        localNotification.applicationIconBadgeNumber = UIApplication.sharedApplication().applicationIconBadgeNumber + 7


        UIApplication.sharedApplication().scheduleLocalNotification(localNotification)


        //initialize and send your notification w/ repeatCount: 0 and fireDate: now
        //hide the banner so the user does not visually see the notification if you wish
    }

您可以在 iOS 中更改两种默认徽章(除了创建自定义徽章之外)。

1. 用户主屏幕上应用图标上的徽章:

UIApplication.sharedApplication().applicationIconBadgeNumber = 计数

UIBarButtonItem 上的徽章，例如标签栏或导航栏项目:

self.viewController.tabBarItem.badgeValue = NSString(format: "%d", count) as String

在这两种情况下，count 的类型都是 Int。显然，第二条语句的第一部分将更改以适应您的选项卡/导航 UIBarButtonItem 结构。

这有帮助吗？
