Attempting to badge the application icon but haven't received permission from the user to badge the application

好长的一串错误信息，该错误信息是在IOS8系统下，进行图标提醒数字设置时，系统给出的提醒设置

究其原因，无非就是IOS8之后，系统需要进行一些必要的设置，才能在图标上显示数字提醒

        if isEightLater {
            let types = UIUserNotificationType.Badge | UIUserNotificationType.Alert | UIUserNotificationType.Sound;
            let settings = UIUserNotificationSettings(forTypes: types, categories: nil);
            UIApplication.sharedApplication().registerUserNotificationSettings(settings);
        } else {
            let types = UIRemoteNotificationType.Badge | UIRemoteNotificationType.Alert | UIRemoteNotificationType.Sound;
            UIApplication.sharedApplication().registerForRemoteNotificationTypes(types);
        }
