有图有真相，首先上实现了的效果。

二 、思路

由于要加载较多数据，那么为了使得界面更近流畅，我采用tableVIEw，其中他的Cell是可以复用的。创建10000个也是秒秒钟的事情。

那么使用上下排列的tableVIEw，每个cell自定义三个Item即可，当然也可以N个，可以自己写好接口。

由于我们想使得tableVIEw可以滚动到指定的cell位置，也就是一格一格滚动，那么我们最好自定义一个tableVIEw继承于系统的tableVIEw.

三 、实现步骤

如果你对于tableVIEw不太熟悉，建议先看官方Testcpp例子.

如果你比较熟悉，那么我就不废话，继续往下讲了。

我们先来自定义一个tableVIEwcell。也就是自定义一行的内容。我相信这个非常简单。

四、准备工作

我们先来自定义一个tableVIEwcell。也就是自定义一行的内容。我相信这个非常简单。

里面都实现了什么，其实就是简单的添加了三个自定义Item.

然后，我们自定义一个tableVIEw实现了两个方法。

一个是去实现滚动到指定cell的方法。

另外一个是我使用触摸的时候需要获得当前使用的cell去判断哪个Item位置位于触摸位置。

我们这里只讲键盘的。那么你可能就用不到这个函数了。

代码如下：

class XtableVIEw : public cocos2d::extension::tableVIEw{public:	/**	* @brIEf scroll to the Designated cell	* @param index --- the IDx of Designated cell	**/	voID scrollToCellindex(ssize_t index);	/***************************************************	* @decripition  if you need Analyzing touch item,*  maby you will use this function to get used cell   	****************************************************/	cocos2d::Vector<cocos2d::extension::tableVIEwCell*> getCurrentCells() const;};

//////////////////////////////////////////////////////////////////////////////////////////////***************************XtableVIEw Class**************************************/////////////////////////////////////////////////////////////////////////////////////////////voID XtableVIEw::scrollToCellindex( ssize_t index ){	this->getContainer()->stopAllActions();	Vec2 offset = _offsetFromIndex(index)*-1;	Vec2 maxOffSet = this->maxContainerOffset();	Vec2 minOffSet = this->minContainerOffset();	float offX = MIN(offset.x,maxOffSet.x);	offX = MAX(offX,minOffSet.x);	float offY = MIN(offset.y,maxOffSet.y);	offY = MAX(offY,minOffSet.y);	this->setContentOffset(Vec2(offX,offY),true);}cocos2d::Vector<cocos2d::extension::tableVIEwCell*> XtableVIEw::getCurrentCells() const{	log("used cell count is %d",_cellsUsed.size());	return this->_cellsUsed;}

好了，那么接下来的重点是列表页的实现。

五、页面具体实现

由于篇幅受限，代码内容比较多，相信大家自己分析就能理解，那么先就不废话了，先上代码吧。不懂的或者有好的建议希望可以留言讨论。
