【iOS新手开发之旅】   http://www.sufeinet.com/thread-24000-1-1.html

应用内购买项目流程，大致分为三个部分：

第一步：iTunes connect设置，包含创建新的发布版本号、创建购买项目（商品）、设置协议税务银行业务、添加沙盒技术测试帐号；

第二步：在项目开发Xcode中设置允许In-App Purchase,然后编写代码：代码部分可以使用原生态的，也可以使用第三方集成好的，需要注意本地存储交易凭证，用于网络不佳或失败的情况下，重新提交。代码完成好之后，打包提交到App Store 等待审核，提交的时候也把之前内购项目勾选一块提交，等审核通过就可以测试了。

第三步：测试是否成功购买，这是需要真机测试的，测试时需要先注销掉测试手机上的App ID,然后在app中点击购买的时候，输入之前添加的沙盒测试帐号。这部分可能会报各种错误，可能是前面两步没有设置完善，也可能是App Store 的问题，不过，有问题就会有对应的解决方法的，网上都能找到的。

这里就直接先讲代码部分：
