CCTableView用来实现滑动列表的效果。本来想用CCScrollView，不过好像有bug，一直达不到效果。最后还是选用了CCTableView

------------------------------------------------------------------------------------相关代码----------------------------------------------------------------------------

（1）CustomTableViewCell.h

#ifndef __CUSTOMTABELVIEWCELL_H__#define __CUSTOMTABELVIEWCELL_H__#include "cocos2d.h"#include "cocos-ext.h"class CustomTableViewCell : public cocos2d::extension::CCTableViewCell{public:	virtual void draw();};#endif /* __CUSTOMTABELVIEWCELL_H__ */

（2）CustomTableViewCell.cpp

#include "CustomTableViewCell.h"USING_NS_CC;void CustomTableViewCell::draw(){	CCTableViewCell::draw();	// draw bounding box	// 	CCPoint pos = getPosition();	// 	CCSize size = CCSizeMake(178, 200);	// 	CCPoint vertices[4]={	// 		ccp(pos.x+1, pos.y+1),	// 		ccp(pos.x+size.width-1, pos.y+1),	// 		ccp(pos.x+size.width-1, pos.y+size.height-1),	// 		ccp(pos.x+1, pos.y+size.height-1),	// 	};	// 	ccDrawColor4B(0, 0, 255, 255);	// 	ccDrawPoly(vertices, 4, true);}

（3）TableViewMenuLayer.h

#ifndef __TABLEVIEWMENULAYER_H__#define __TABLEVIEWMENULAYER_H__//城市界面右边的滑动菜单项列表Layer,这个用的是CCTableView#include "cocos2d.h"#include "cocos-ext.h"using namespace cocos2d;using namespace cocos2d::extension;class TableViewMenuLayer : public cocos2d::CCLayer, public cocos2d::extension::CCTableViewDataSource, public cocos2d::extension::CCTableViewDelegate{public:	static TableViewMenuLayer *instance;public:	TableViewMenuLayer(void);	~TableViewMenuLayer(void);public:	virtual bool init();  	CREATE_FUNC(TableViewMenuLayer);	virtual void scrollViewDidScroll(cocos2d::extension::CCScrollView* view) {};	virtual void scrollViewDidZoom(cocos2d::extension::CCScrollView* view) {}	virtual void tableCellTouched(cocos2d::extension::CCTableView* table, cocos2d::extension::CCTableViewCell* cell);	virtual cocos2d::CCSize cellSizeForTable(cocos2d::extension::CCTableView *table);	virtual cocos2d::extension::CCTableViewCell* tableCellAtIndex(cocos2d::extension::CCTableView *table, unsigned int idx);	virtual unsigned int numberOfCellsInTableView(cocos2d::extension::CCTableView *table);};#endif //__TABLEVIEWMENULAYER_H__

（4）TableViewMenuLayer.cpp

#include "TableViewMenuLayer.h"#include "CustomTableViewCell.h"#include "MenuInfoLayer.h"using namespace cocos2d;using namespace cocos2d::extension;TableViewMenuLayer::TableViewMenuLayer(void){}TableViewMenuLayer::~TableViewMenuLayer(void){}//初始化静态成员  TableViewMenuLayer* TableViewMenuLayer::instance=NULL;

break;		case 1: string = CCString::createWithFormat("%s", "WORLD"); break;		case 2: string = CCString::createWithFormat("%s", "BATTLE"); break;		case 3: string = CCString::createWithFormat("%s", "CityInfo"); break;		case 4: string = CCString::createWithFormat("%s", "Commander"); break;		case 5: string = CCString::createWithFormat("%s", "Equipment"); break;		case 6: string = CCString::createWithFormat("%s", "Quest");

break;		default:string = CCString::createWithFormat("%s", "Error");	}		// the cell	CCTableViewCell *cell = table->dequeueCell();	if (!cell) {		// the sprite		cell = new CustomTableViewCell();		cell->autorelease();		CCSprite *sprite = CCSprite::create("CloseNormal.png");		sprite->setAnchorPoint(ccp(0, 0));		sprite->setPosition(ccp(0, 30));		sprite->setTag(456); 		cell->addChild(sprite);		// the label		CCLabelTTF *label = CCLabelTTF::create(string->getCString(), "Thonburi", 13);		label->setPosition(ccp(40, 20));		label->setTag(123); 		cell->addChild(label);	}	else	{		// the sprite		cell->removeChildByTag(456,true);		CCSprite *sprite ;		switch(idx)		{			case 0: sprite = CCSprite::create("city.png");break;			case 1: sprite = CCSprite::create("world.png");break;			case 2: sprite = CCSprite::create("battle.png");break;			case 3: sprite = CCSprite::create("cityInfo.png");break;			case 4: sprite = CCSprite::create("hero.png");break;			case 5: sprite = CCSprite::create("equipment.png");break;			case 6: sprite = CCSprite::create("task.png");break;			case 7: sprite = CCSprite::create("treasure.png");break;			case 8: sprite = CCSprite::create("army.png");break;			case 9: sprite = CCSprite::create("guild.png");break;			case 10: sprite = CCSprite::create("rank.png");break;			case 11: sprite = CCSprite::create("report.png");break;			case 12: sprite = CCSprite::create("message.png");break;			case 13: sprite = CCSprite::create("system.png");break;			case 14: sprite = CCSprite::create("mall.png");break;			case 15: sprite = CCSprite::create("friend.png");break;			default:sprite = CCSprite::create("CloseNormal.png");		}		sprite->setAnchorPoint(ccp(0, 0));		sprite->setPosition(ccp(0, 35));		sprite->setTag(456); 		cell->addChild(sprite);				// the label		CCLabelTTF *label = (CCLabelTTF*)cell->getChildByTag(123);		label->setString(string->getCString());	}	return cell;}unsigned int TableViewMenuLayer::numberOfCellsInTableView(CCTableView *table){	return 16;}

（5）CityScene.cpp 调用界面，调用时直接在scene里调用该layer（包含包含的头文件） #include "TableViewMenuLayer.h"		// add TableViewMenuLayerTableViewMenuLayer *tableViewMenuLayer = TableViewMenuLayer::create();TableViewMenuLayer::instance=tableViewMenuLayer;this->addChild(tableViewMenuLayer,10);
