Hi You need to register UIUserNotificationSettings like this
嗨，您需要像这样注册 UIUserNotificationSettings
UIUserNotificationSettings* notificationSettings = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeSound categories:nil];
[[UIApplication sharedApplication] registerUserNotificationSettings:notificationSettings];
[UIApplication sharedApplication].applicationIconBadgeNumber = 1;

Registering for Notification Types in iOS
In iOS 8 and later, apps that use either local or remote notifications must register the types of notifications they intend to deliver. The system then gives the user the ability to limit the types of notifications your app displays. The system does not badge icons, display alert messages, or play alert sounds if any of these notification types are not enabled for your app, even if they are specified in the notification payload. Link: Docs
@property(nonatomic) NSInteger applicationIconBadgeNumber; // set to 0 to hide. default is 0. In iOS 8.0 and later, your application must register for user notifications using -[UIApplication registerUserNotificationSettings:] before being able to set the icon badge.
在 iOS 中注册通知类型
在 iOS 8 及更高版本中，使用本地或远程通知的应用程序必须注册它们打算传递的通知类型。然后，系统使用户能够限制您的应用程序显示的通知类型。如果您的应用程序未启用这些通知类型中的任何一种，即使它们在通知负载中指定，系统也不会标记图标、显示警报消息或播放警报声音。链接：文档
@property(nonatomic) NSInteger applicationIconBadgeNumber; // 设置为 0 以隐藏。默认值为 0。在 iOS 8.0 及更高版本中，您的应用程序必须使用 -[UIApplication registerUserNotificationSettings:] 注册用户通知，然后才能设置图标徽章。
So I think you must register badges for change number notification.
因此，我认为您必须为更改号码通知注册徽章。

Set it in you Appdelegate.mFile in didFinishLaunchingmethod...
将它设置在你的Appdelegate.m文件中didFinishLaunching方法...
application.applicationIconBadgeNumber = 5.
application.applicationIconBadgeNumber = 5.
and change your current date to after 2 days and restart Your iPhone.. and test again. It should be working fine.
并将您的当前日期更改为 2 天后并重新启动您的iPhone.. 并再次测试。它应该工作正常。
