Cocos2dx(1) extensions_UIListView

Cocos2dx 2.2.1

此处的UIListView并没有通过Cocostudio获取得到，由纯Code产生，实现如下

ShowGame.h

    void menuCloseCallback(CCObject* pSender);
    void listViewEvent(CCObject *pSender, ListViewEventType type);//UIListView响应事件
    void listViewItemEvent(CCObject *pSender, TouchEventType type); //Item(Layout)点击事件


    UIListView *p_listView;//ListView

    int m_nCount;//用于初始化UIListView数组，遍历数据

上面实现的效果如下图，凑合着看 囧~~
