cocos2d-x学习之一：cocos2d-x程序的生命周期

1.main.m(ios为例)程序入口：cocos2d::CCApplication::sharedApplication().run();

2.程序启动之后会调用AppDelegate.cpp中的回调applicationDidFinishLaunching：

bool AppDelegate::applicationDidFinishLaunching()

{

// initialize director

CCDirector *pDirector = CCDirector::sharedDirector();

pDirector->setOpenGLView(&CCEGLView::sharedOpenGLView());

// enable High Resource Mode(2x, such as iphone4) and maintains low resource on other devices.

pDirector->enableRetinaDisplay(true);

// 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);

// create a scene. it's an autorelease object

CCScene *pScene = MainScene::scene();

// run

pDirector->runWithScene(pScene);

return true;

}

3.通过调用

// create a scene. it's an autorelease object

CCScene *pScene = MainScene::scene();

// run

pDirector->runWithScene(pScene);

来实现加载主界面。
