苹果内购开发（含掉单问题优化）
一.通用流程梳理
1.原来老的的流程（第七步有掉单风险）
第1. 先创建订单
第2.订单返回正常后（有订单号），启动苹果购买流程，调用苹果接口
第3.如果没登录会要求用户登录appleId，如果已经登录，会弹出购买确认框（该弹框也是苹果控制）
第4.点击购买后，等待直接结果回调
第5.扣款成功后，苹果回调接口里面会有receipt 数据。
第6.如果receipt不为空，将改值作为入参，调用后台印证支付成功接口。
第7.验证接口返回正常后，通知页面重新请求余额接口进行刷新。（验证订单有效的情况，可能会导致掉单情况）

2.优化后的流程图如下（添加本地数据库机制，如果印证成功，就清除数据库同时结束交易；如果印证不成功（error或faliure），就不清除交易，调用苹果自己的重试机制）

二.具体实现代码如下

@interface AppDelegate ()

@end

@implementation AppDelegate

    //支付
    [[PayCenter sharedPayCenter] startInit];

    return YES;
}

第一次提交内购一定要选择添加内功项目,不然上架的app是不会开启内购功能的
