IOS10: 未显示徽章数

Question

我正在使用以下代码在我的应用程序图标上显示一个数字作为徽章：

func triggerNotification(iAmountToday: Int) {
  UNUserNotificationCenter.currentNotificationCenter().requestAuthorizationWithOptions([.Badge, .Sound, .Alert]) { (granted, error) in
    if granted {
      let content = UNMutableNotificationContent()
      content.badge = iAmountToday
      content.categoryIdentifier = "com.psv.localNotification"
      let trigger = UNTimeIntervalNotificationTrigger.init(timeInterval: 1.0, repeats: false)
      let request = UNNotificationRequest.init(identifier: "AmountTodayUpdate", content: content, trigger: trigger)

      let center = UNUserNotificationCenter.currentNotificationCenter()
      center.addNotificationRequest(request, withCompletionHandler: { (error) in
        if (error != nil) {
          print (error)
        }
      })
    }
  }
}

虽然没有抛出错误，但徽章从未显示在应用程序图标上。

我做错了什么？

干杯

Answer 1

Swift3.0，iOS10.

你应该替换：

 UNUserNotificationCenter.currentNotificationCenter().requestAuthorizationWithOptions([.Badge, .Sound, .Alert]) { (granted, error) in

与：

UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .badge, .sound]) { (success, error) in

这对我有用。
