这些天被cocos2dx如何读取xml困惑着,现在总结总结,如有错误,欢迎指正!
先新建一个cocos2dx的工程
HelloWorldScene.cpp中的代码如下:
- #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",
- this,153); list-style:decimal-leading-zero outside; color:inherit; line-height:18px; margin:0px!important; padding:0px 3px 0px 10px!important"> menu_selector(HelloWorld::menuCloseCallback));
- CC_BREAK_IF(!pCloseItem);
- //Placethemenuitembottom-rightconner.
- pCloseItem->setPosition(ccp(CCDirector::sharedDirector()->getWinSize().width-20,20));
- //Createamenuwiththe"close"menuitem,it'sanautoreleaSEObject.
- 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");
- /*

- <string>comeontom</string>

- 这些关键词,则输出最后一个
