Objective-C 中实现 In-App Purchase 功能的代码详解

In-App Purchase（内购）是移动应用开发者实现盈利的重要方式之一。在 Objective-C 中，iOS 应用可以通过苹果的 In-App Purchase API 来实现内购功能。本文将详细介绍如何在 Objective-C 中使用 In-App Purchase API，包括购买流程、状态监听、错误处理等方面。

准备工作

在开始之前，请确保你的 Xcode 项目已经配置了 In-App Purchase 功能。以下是配置步骤：

1. 打开 Xcode，创建一个新的 iOS 项目。

2. 在项目导航器中，选择你的项目。

3. 点击项目设置，选择“Capabilities”标签页。

4. 启用“In-App Purchase”。

5. 点击“+”按钮添加内购项目。

6. 为内购项目设置名称、描述和价格等信息。

1. 导入 In-App Purchase 相关头文件

在你的 Objective-C 文件中导入 In-App Purchase 相关的头文件：

objective-c
import <StoreKit/StoreKit.h>

2. 设置通知监听

为了接收 In-App Purchase 相关的通知，需要在 `Info.plist` 文件中添加以下代码：

```xml

<key>UIApplicationSupportsAppExtensions</key>

<true/>

<key>UIApplicationMainSceneManifest</key>

<dict>

<key>UIApplicationSceneManifest</key>

<dict>

<key>UIApplicationSupportsMultipleScenes</key>

<key>UIApplicationRequiredDeviceCapabilities</key>
