我得实现思路是：1，首先点击按钮，调用拉取商品信息，2，在苹果写好的接收响应函数里对应用户点击的购买类型发起购买操作。…
问题出在:
购买: 第一次购买，流程完全正确；第二次购买，则走了2次购买，第三次购买，则走了3次购买…
取消购买: 情况也是这样子。
调用日志:
不知具体哪步出错了，还望大神帮忙检查下，代码如下:
#import "SSBuyGoldCoinsViewController.h"
#include "PurchaseManager.h"
#include "cocos2d.h"
USING_NS_CC;
#define COMMODITY6 0
#define COMMODITY12 1
#define COMMODITY24 2
#define ProductID_IAP6 @"U170001" // 6元
#define ProductID_IAP12 @"U170002" // 12元
#define ProductID_IAP18 @"U170003" // 18元
