quick-cocos2dx中 lua 和oc的通信

        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>

{
    IAP60DM = 0,
    IAP130DM,
    IAP370DM,
    IAP720DM,
    IAP1650DM,
    IAPWUJIN,
}buyDiamondTag;

     int buyType;
}

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。
