ios - 从AWS SNS发送推送通知时如何自动增加角标(Badge)数量？

Question

我正在使用 Amazon Web Services 向 IOS 应用程序发送“推送通知”。如何在 swift 2 中自动增加角标(Badge)编号？

我在 AppDelegate 中使用以下代码:

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {


    let notificationTypes : UIUserNotificationType = [.Alert, .Badge, .Sound]
    let notificationSettings : UIUserNotificationSettings = UIUserNotificationSettings(forTypes: notificationTypes, categories: nil)
    UIApplication.sharedApplication().registerUserNotificationSettings(notificationSettings)
    UIApplication.sharedApplication().registerForRemoteNotifications()

    UIApplication.sharedApplication().applicationIconBadgeNumber = 0        
    return true
    }

你不能只说“增加角标(Badge)数量”。

它的工作方式是，您必须在您显式发送的每个推送通知中告知角标(Badge)计数。
