iPhone推送通知？

我对iPhone很新，所以如果这是一个明显的问题，请道歉。

底栏（电话，邮件，Safari + iPod）上的默认程序是唯一可以显示“新”事件计数的应用程序吗？它们是在底栏上吗？

不，底行的“默认”应用程序不是唯一可以接收推送通知或显示号码徽章的应用程序。

推送通知和数字徽章之间不一定存在关系。应用程序可以在没有推送通知的情况下拥有数字徽章（Mint会浮现在脑海中）并且可以具有没有数字徽章的推送通知（例如，MLB At Bat）。

任何已实施推送通知的应用都可以在图标上显示数字徽章。消息是另一个带推送通知的Apple应用程序。某些第三方应用也有推送通知。

Not exactly, the counts come from the app programming itself. Some have the count integrated, some don't.

You can actually change which apps are on the Dock (bottom bar) to whatever you like. And various apps have the new event count. For instance, I use The AT&T MyWireless app, and when my bill is due, I get a push notification there as well. Also when your apps have updates, you'll get one from the App Store icon. Any application that supports notifications will get a badge.
