quick-cocos2dx中 lua 和oc的通信中，游戏的逻辑是用lua代码，系统是ios系统，主要是oc代码。那么，如果要调用支付代码，该如何调用呢？

这里两者沟通的桥梁主要是使用luaoc这个模块。废话不多说，下面是lua端的例子。代码如下：

local function buySuccess(receipt)
print(" buySuccess! "..receipt)

print(" 调用lua代码向服务器请求验证receipt的正确性")
end

local products = {
productIndex = 1,
}

luaoc.callStaticMethod("MyObserver","buyProduct",products)
luaoc.callStaticMethod("MyObserver","registerScriptHandler",{listener = buySuccess})

可以明确的看出， products是参数，buySuccess是回调函数，buyProduct是MyObserver的一个类。

下面给出oc代码的例子：

--MyObserver.h

#import <UIKit/UIKit.h>
#import <StoreKit/StoreKit.h>


enum
{
IAP60DM = 0,
IAP130DM,
IAP370DM,

}buyDiamondTag;

代码都有，主要是写了一个buyProduct的函数。这个函数在lua中调用，在oc中实现，实现其中的功能。写了一个mm文件。

这样就能够沟通了。
