在创建完了工程之后，我们可以看到AppDelegate这个文件，我们打开看下这里面有什么：

AppDelegate::AppDelegate() { //1，构造AppDelegate}AppDelegate::~AppDelegate() {}bool AppDelegate::applicationDidFinishLaunching() {//3，在2初始化完之后进入，结束初始化appDelegate    // initialize director    CCDirector* pDirector = CCDirector::sharedDirector();    CCEGLView* pEGLView = CCEGLView::sharedOpenGLView();    pDirector->setOpenGLView(pEGLView);    // turn on display FPS    pDirector->setDisplayStats(true);    // set FPS. the default value is 1.0/60 if you don't call this    pDirector->setAnimationInterval(1.0 / 60);CCScene * pScene = CCScene::create();    GameDemoManager * pLayer = new GameDemoManager();pLayer->initGame();    pLayer->autorelease();    pScene->addChild(pLayer);    pDirector->runWithScene(pScene);    return true;}// This function will be called when the app is inactive. When comes a phone call,it's be invoked toovoid AppDelegate::applicationDidEnterBackground() {//4,当手机处于后台运行的时候，进入该处    CCDirector::sharedDirector()->stopAnimation();    // if you use SimpleAudioEngine, it must be pause    // SimpleAudioEngine::sharedEngine()->pauseBackgroundMusic();}// this function will be called when the app is active againvoid AppDelegate::applicationWillEnterForeground() { /,2，构造完了AppDelegate之后进入初始化application    CCDirector::sharedDirector()->startAnimation();    // if you use SimpleAudioEngine, it must resume here    // SimpleAudioEngine::sharedEngine()->resumeBackgroundMusic();}

从上面分析：

AppDelegate其实就是整个程序的入口，它的初始化步骤就是上面的1-3，4则是在手机后台运行该程序时所调用的
