In-App Purchase--Introduction(1)

Introduction

In-App Purchase allows you to embed a store directly within your application. You implement In-App Purchase in your application using the Store Kit framework. Store Kit connects to the App Store on your application's behalf(代表你的应用程序) to securely process payments from the user. Store Kit prompts the user to authorize the payment, then notifies(通知) your application so that it can provide items the user purchased. You can use this in-application payment functionality to collect payment for enhanced functionality or additional content usable by your application.

For example, you could use In-App Purchase to implement any of the following scenarios:

  • A basic version of your application with additional premium(额外的) features.
  • A book reader application that allows the user to purchase and download new books.
  • A game that offers new environments (levels) to explore.
  • An online game that allows the player to purchase virtual property.

Important In-App Purchase only collects payment. You must provide any additional functionality, including unlocking built-in features or downloading content from your own servers. This documentation details the technical requirements of adding a store to your application. For more information on the business requirements of using In-App Purchase, see the App Store Resource Center. You must also read your licensing agreement(许可协议) for the definitive(最终) treatment of what you may sell and how you are required to provide those products in your application.
