About In-App Purchase
In-App Purchase allows you to embed a store inside your app using the Store Kit framework. This framework connects to the App Store on your app’s behalf to securely process payments from users, prompting them to authorize payment. The framework then notifies your app, which provides the purchased items to users. Use In-App Purchase to collect payment for additional features and content.
内置購買使用Store Kit 架構在應用程式裡内置一個商店。該架構把你的應用程式的行為連接配接到應用商店來安全地處理使用者的支付，促使他們授權支付。 然後架構給你的應用程式發送通知，該應用程式提供了使用者購買的商品。使用内置購買可以為額外的功能和内容提供支付。
For example, using In-App Purchase, you can implement the following scenarios:
比如，使用内置購買，你可以實作以下内容：
-
A basic version of your app with additional premium features
一個帶有額外進階功能的應用程式的基礎版本。
-
A magazine app that lets users purchase and download new issues
一個可以讓使用者購買和下載下傳新刊的雜志應用。
-
A game that offers new levels to explore
一個提供新關卡讓使用者攻克的遊戲。
-
An online game that allows players to purchase virtual property

概論
At a high level, the interactions between the user, your app, and the App Store during the In-App Purchase process take place in three stages, as shown in Figure I-1. First, the user navigates to your app’s store and your app displays its products. Second, the user selects a product to buy and the app requests payment from the App Store. Third, the App Store processes the payment and your app delivers the purchased product.
從高層次來說，内置購買過程處理期間，使用者，應用程式和應用商店之間的互動發生在三個階段，如圖I-1。首先，使用者導航到你的應用程式商店，你的應用程式顯示其産品。 其次，使用者選擇一個産品購買，應用程式從應用商店請求支付。 最後，應用商店處理該支付，你的應用程式傳遞被購産品。

Subscriptions Require Additional Application Logic
三、訂閱需要更多應用邏輯
Apps that offer subscriptions need to keep track of when the user has an active subscription, respond to expiration and renewal, and determine what content the user has access to.
提供訂閱的應用程式需要随時監控使用者何時有一個活動訂閱，響應到期和續期，然後決定使用者通路什麼内容。
