什么是内购
首先得分清楚 内购和Apple Pay。
一、Apple Pay：是一种支付方式，跟支付宝、微信支付是类似的，这里就不详细介绍了。
二、内购：只要在iPhone App上购买的不是实物产品(也就是虚拟产品如qq币、鱼翅、电子书......) 都需要走内购流程,苹果这里面抽走30%。
内购流程
一、填写协议,税务和银行业务
1、登录https://appstoreconnect.apple.com，选择进入App Store Connect。
2、进入“协议、税务和银行业务”
3、内购用的是付费应用程序，先签署《付费应用程序协议》，同意后状态变更为“用户信息待处理”，等待审核。
4、状态更改完毕后，点击“开始设置税务、银行业务和联系信息”。
a.添加银行账户,按照要求填写相关内容即可。
b.选择报税表，并填写。(我是可爱的中国公民，在美国有没有商业活动，所以我填的是否。)
然后继续填写报税表，按照填写要求填写就行了（要是英文阅读有点困难，那就双击网页，应该会有翻译成中文的功能；没有的话，那就词典。。。你懂得，哈哈哈）， 我是个人开发者账户相对公司开发者账户填的会少一点，不过没关系。都是一些基本信息。
c.填写联系信息，一共5个。高级管理、财务、技术、法务、营销（可重复，像我这种人才就是5个职位都是我，开玩笑的，勿当真）。
5、上面的税务表填完了之后，点击“我的APP”，进入到项目APP的信息页，点击功能，在弹出的页面点击App内购买项目后面的+。
这里我以消耗型为例
创建完成之后 填写内购买项目信息
信息填写完成了点击右上角的 “存储”，然后点击左边 “App 内购买项目”。出现“元数据丢失”说明里面信息没填写完整，在点进去填写。直到显示“准备提交”。
6、添加沙箱测试人员
7、我们需要在工程里配置好证书，测试证书是必须的因为我们内购需要连接到苹果的App Store的，需要正式的测试证书才能测试，同时把下图工程中的这一配置打开

// 验证购买，在每一次购买完成之后，需要对购买的交易进行验证
// 所谓验证，是将交易的凭证进行"加密"，POST请求传递给苹果的服务器，苹果服务器对"加密"数据进行验证之后，

// 有些“内购助手”同样会拦截验证凭据，返回一个伪造的验证结果
// 所以在开发时，对凭据的检验要格外小心

三、注意事项
1.接入内购后把支付宝、微信支付的SDK删掉，苹果那边能扫出来（因为这个原因我被拒过）。
2.内购商品是和项目一起提交然后审核过了商品才有效！
3.测试内购一定要用真机测试，商品信息如果无效，一般是 商品还没有审核通过 ！
