cocos2dx中的IAP实现：一

A.苹果内购IAP两种模式流程：

1.内置模式：
app从app store 获取产品信息
用户选择需要购买的产品
app发送支付请求到app store
app store 处理支付请求，并返回transaction信息
app将购买的内容展示给用户

2.服务器模式的流程:
app从服务器获取产品标识列表
app从app store 获取产品信息
用户选择需要购买的产品
app 发送支付请求到app store
app store 处理支付请求，返回transaction信息
app 将transaction receipt 发送到服务器
服务器收到收据后发送到app stroe验证收据的有效性
app store 返回收据的验证结果
根据app store 返回的结果决定用户是否购买成功

上述两种模式的不同之处主要在于：交易的收据验证，内建模式没有专门去验证交易收据，而服务器模式会使用独立的服务器去验证交易收据。内建模式简单快捷，但容易被破解。服务器模式流程相对复杂，但相对安全。

B.内置模式代码实现：添加StoreKit.framework

调用例子：

  /* Ios IAP entrance */        int payPrice = pNotify->GetSubType();        std::string productIdStr;        switch (payPrice)        {            case 1024:                productIdStr = "ttz_yk";                break;            case 1025:                productIdStr = "ttz_6";                break;            default:                break;        }        NSLog(@"----------当前商品ID: %s", productIdStr.c_str());        NSString* ocProductIdStr = [NSString stringWithFormat:@"%s",                                    productIdStr.c_str()];        PaymentController* pPayController = [[PaymentController alloc] initWithPayConstructor:ocProductIdStr];        [pPayController purchaseFunc];

PS：内置模式并没有做订单凭证后台验证，整个流程看起来都非常简单，所以是很不安全的方式，容易被破解内购产品刷单，下篇blog处理服务器模式
