quick-cocos2dx中 lua 和oc的通信

quick-cocos2dx中 lua 和oc的通信中，遊戲的邏輯是用lua代碼，系統是ios系統，主要是oc代碼。那麼，如果要調用支付代碼，該如何調用呢？

這裏兩者溝通的橋樑主要是使用luaoc這個模塊。廢話不多說，下面是lua端的例子。代碼如下：

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

print(" 調用lua代碼向服務器請求驗證receipt的正確性")
end

local products = {
productIndex = 1,
}

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

可以明確的看出， products是參數，buySuccess是回調函數，buyProduct是MyObserver的一個類。

下面給出oc代碼的例子：

--MyObserver.h

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

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