iOS 苹果内购详细步骤

一、设置协议等相关

1.点击协议、税务和银行业务
主协议界面
Contact info :联系人信息
Bank info :银行信息
Tax info :税务信息

3.点击 Contact Info 下面的Set Up，设置联系人信息，然后点击 Add New Contract，添加新的联系信息。
5.选择联系人，因为我是独立开发，所以填写的自己的，如果你是多人开发，你可以添加多个联系人。

Senior Management：高级管理人员
Financial ：财务
Technical ：技术支持
Legal ：法务
Marketing ：市场推广

添加完成之后，对应选择好就行。
二、创建项目的内购条目
三、添加沙盒测试账号
四、代码集成
