iOS开发支付篇——内购(IAP)详解

先看gif图

具体步骤：

协议、税务和银行业务 信息填写

内购商品的添加

添加沙盒测试账号

内购代码的具体实现

内购的注意事项

流程

1.注册app,填写协议、税务和银行业务

注册app,需要唯一设置Bundle identifier，然后详细填写协议、税务和银行业务，此个步骤这里就不在写了

（【官方地址】(https://developer.apple.com/library/archive/technotes/tn2259/_index.html#//apple_ref/doc/uid/DTS40009578)）。

2.内购商品的添加

我的App—>准提交的项目—>功能—>App内购买项目：添加内购商品信息

3.添加沙盒测试账号

iTunes Connect —>用户和职能 —>沙盒测试技术员：添加沙盒测试账号

4.代码实现过程

写了一个购买的单例
