Ios [UIApplication sharedApplication]。ApplicationOnBadgeNumber不更新徽章

我的一个应用程序中有一个特殊的站点。我应该打电话给：

[UIApplication sharedApplication].applicationIconBadgeNumber=<value>

我还试图通过通知的方式进行设置，但通知会显示，但徽章不会更新。

可能有什么问题，或者我怎样才能知道得更清楚？

首先，注册UIUserNotificationSettings

UIUserNotificationSettings* notificationSettings = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert | UIUserNotificationTypeBadge categories:nil];

[[UIApplication sharedApplication] registerUserNotificationSettings:notificationSettings];

[UIApplication sharedApplication].applicationIconBadgeNumber = <value>;

UIUserNotificationSettings*notificationSettings=[UIUserNotificationSettings设置类型：UIUserNotificationTypeAlert | UIUserNotificationTypeBadge类别：nil]；
[[UIApplication sharedApplication]registerUserNotificationSettings:notificationSettings]；
[UIApplication sharedApplication].applicationIconBadgeNumber=；

这要容易得多。显然，iOS在更新后从应用程序设置中删除了“显示徽章图标”。启用后，徽章将正确更新。无论如何，感谢您的支持。

请检查此项，正如您在我的代码片段中看到的，这就是我在徽章更新之前所做的。很抱歉，我没有看到。。。但我认为你可以从这个答案中得到帮助

UIUserNotificationSettings* notificationSettings = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert | UIUserNotificationTypeBadge categories:nil];

[[UIApplication sharedApplication] registerUserNotificationSettings:notificationSettings];

[UIApplication sharedApplication].applicationIconBadgeNumber = <value>;
