先新建一个cocos2dx的工程

HelloWorldScene.cpp中的代码如下：

[cpp] 
   view plain 
   copy 
   print 
   ? 
    
   
 
   
 #include"HelloWorldScene.h"
 
 usingnamespacecocos2d;
 CCScene*HelloWorld::scene()
 {
 CCScene*scene=NULL;
 do
 {
 //'scene'isanautoreleaSEObject
 scene=CCScene::create();
 CC_BREAK_IF(!scene);
 
//'layer'isanautoreleaSEObject
 HelloWorld*layer=HelloWorld::create();
 CC_BREAK_IF(!layer);
//addlayerasachildtoscene
 scene->addChild(layer);
 }while(0);
//returnthescene
 returnscene;
 }
//on"init"youneedtoinitializeyourinstance
 boolHelloWorld::init()
boolbRet=false;
//////////////////////////////////////////////////////////////////////////
 //superinitfirst
 CC_BREAK_IF(!CCLayer::init());
//addyourcodesbelow...
//1.Addamenuitemwith"X"image,whichisclickedtoquittheprogram.
//Createa"close"menuitemwithcloseicon,it'sanautoreleaSEObject.
 CCMenuItemImage*pCloseItem=CCMenuItemImage::create(
 "CloseNormal.png",
 "CloseSelected.png",85)"> this,153); list-style:decimal-leading-zero outside; color:inherit"> menu_selector(HelloWorld::menuCloseCallback));
 CC_BREAK_IF(!pCloseItem);
//Placethemenuitembottom-rightconner.
 pCloseItem->setPosition(ccp(CCDirector::sharedDirector()->getWinSize().width-20,20));
//Createamenuwiththe"close"menuitem,85)"> CCMenu*pMenu=CCMenu::create(pCloseItem,NULL);
 pMenu->setPosition(CCPointZero);
 CC_BREAK_IF(!pMenu);
//AddthemenutoHelloWorldlayerasachildlayer.
 this->addChild(pMenu,1);
//2.Addalabelshows"HelloWorld".
//Createalabelandinitializewithstring"HelloWorld".
//最外面的CCDictionary
 CCDictionary*pDict=CCDictionary::createWithContentsOfFile("strings.xml");
//第二层CCDictionary
 CCDictionary*pDict_2=newCCDictionary();
 pDict_2->retain();
 pDict_2=(CCDictionary*)pDict->objectForKey("special");
/*
如果在同一个key下面存在<string>hhhhh</string>
<string>comeontom</string>
<true></true>
这些关键词，则输出最后一个
*/
 CCLOG("pDict_2:%s",((CCString*)pDict_2->valueForKey("special_1"))->getCString());
/*第三层下面说的是Array中包含string
<key>special_2</key>
<array>
<string>comeontom1</string>

<string>comeontom3</string>
</array>
 CCArray*pArray2=newCCArray();
 pArray2->retain();
 pArray2=(CCArray*)pDict_2->objectForKey("special_2");
 for(inti=0;i<pArray2->count();i++)
 CCLOG("pArray2%i:%s",i+1,((CCString*)pArray2->objectAtIndex(i))->getCString());
<key>special_3</key>
<integer>45.0</integer>
<integer>3</integer>
<integer>43.444</integer>
 CCArray*pArray3=newCCArray();
 pArray3->retain();
 pArray3=(CCArray*)pDict_2->objectForKey("special_3");
inti=0;i<pArray3->count();i++)
 CCLOG("pArray3%i:%s",((CCString*)pArray3->objectAtIndex(i))->getCString());
/*第三层

"special_5"))->getCString());
 CCLOG("strings.xmlCounts:%d",pDict->count());
 CCLOG("pDict:%s",pDict);
 CCArray*pArray=newCCArray();
 pArray=pDict->allKeys();//把所有的键值付给pArray
 for(inti=0;i<pArray->count();i++)
 CCLOG("pArray%i:%s",((CCString*)pArray->objectAtIndex(i))->getCString());
 }
 CCLabelTTF*pLabel=CCLabelTTF::create(((CCString*)pDict->objectForKey("chinese1"))->getCString(),"Arial",24);
/*CCLabelTTF*pLabel=CCLabelTTF::create(((CCString*)pArray->objectAtIndex(3))->getCString(),"Arial",24);*/
//CCLabelTTF*pLabel=CCLabelTTF::create("HelloWorld",24);
 CC_BREAK_IF(!pLabel);
//Getwindowsizeandplacethelabelupper.
 CCSizesize=CCDirector::sharedDirector()->getWinSize();
 pLabel->setPosition(ccp(size.width/2,size.height-50));
//AddthelabeltoHelloWorldlayerasachildlayer.
 this->addChild(pLabel,0); background-color:inherit">//3.Addaddasplashscreen,showthecocos2dsplashimage.
 CCSprite*pSprite=CCSprite::create("HelloWorld.png");
 CC_BREAK_IF(!pSprite);
//Placethespriteonthecenterofthescreen
 pSprite->setPosition(ccp(size.width/2,size.height/2));
//AddthespritetoHelloWorldlayerasachildlayer.
 this->addChild(pSprite,0);
 bRet=true;
 returnbRet;
 voidHelloWorld::menuCloseCallback(CCObject*pSender)
//"close"menuitemclicked
 CCDirector::sharedDirector()->end();
 }

strings.xml代码如下：

[html] ?

<?xmlversion="1.0"encoding="UTF-8"?>

<!DOCTYPEplistPUBLIC"-//Apple//DTDPLIST1.0//EN""http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plistversion="1.0">
<dict>
<key>special</key>
<string>
<dict>
<key>special_1</key>
<string>hhhhh</string>
<string>comeontom</string>
<true></true>
<key>special_2</key>
<array>
<string>comeontom1</string>
<string>comeontom2</string>
<string>comeontom3</string>
</array>
<key>special_3</key>
<integer>45.0</integer>
<integer>3</integer>
<integer>43.444</integer>
<key>special_4</key>
<real>多媒体</real>
<key>special_5</key>
<false></false>
</dict>
</string>
<key>chinese1</key>
<string>美好的一天</string>
<key>japanese</key>
<string>良い一日を</string>
<key>spanish</key>
<string>Buendía</string>
</plist>

最后来个总结：

dict:建立字典 key：字典里面的关键词 integer：整形，其实和string、real的功能差不多，起配对作用 real：和integer、string的功能差不多，起配对作用 true：<true></true>如果这样写，输出的是1 false：<false></false> 输出的是0 string：和integer、real的功能差不多，起配对作用 array：建立数组
