iOS APNS开发[沙箱] vs生产

1)我可以在应用商店中启动一个只能注册APNS开发者证书的推送通知的应用程序吗？或者我需要使用APNS Production来应用我想要在应用商店上启动的应用程序吗？

2)一般来说,除了“开发APNS”和“生产APNS”之外,功能原因是什么,这可以告诉我的决定.特别是为什么我选择为我的应用程序实现APNS Developer证书,以及为什么不在生产推送帐户上运行所有内容？

这是苹果公司在网站上所说的,但它并没有达到我的问题的核心：

Development: Use the development environment for initial development and testing of the provider app. It provides the same set of services as the production environment,although with a smaller number of server units. The development environment also acts as a virtual device,enabling simulated end-to-end testing.
You access the development environment at gateway.sandbox.push.apple.com,outbound TCP port 2195.

Production: Use the production environment when building the production version of the provider app. Apps using the production environment must meet Apple’s reliability requirements.
