【js语法相关】
遍历对象或数组obj，执行函数context.iterator，函数返回false表示break
cc.each(obj,iterator,context)

从源对象拷贝所有属性到目标对象，并返回目标对象
cc.extend(target,src0,src1..)

cc.isFunction(obj)
cc.isNumber(obj)
cc.isString(obj)
cc.isArray(obj)
cc.isUndefined(obj)
cc.isObject(obj)

定义原型的getter和setter，这样就可用赋值的方式进行set函数的调用，更方便
cc.defineGetterSetter(proto,prop,getter,setter)

【async】
任务流程的控制
cc.async = {
	series : function (tasks,cb,target) {},parallel : function (tasks,waterful : function (tasks,map : function (tasks,mapLimit : function (tasks,};

【path路径操作】
cc.path = {
	join: function () {},// 'a','b.png' -> 'a/b.png'
	extname: function (str) {},//  -> '.png'; null
	basename: function (str,ext) {},// 'a/b.png' -> 'b.png'; 'a/b.png','.png' -> 'b'
	dirname: function (str) {},// 'a/b/c.png' -> 'a/b'
	changeExtname: function(str,// 'a/b.png','.plist' -> 'a/b.plist'
	changeBasename: function(str,base,sameExt) {},// 'a/b.plist','c.plist' -> 'a/c.plist'; 'a/b.plist','c',true -> 'a/c.plist'
};

【loader加载器】
cc.loader = {
	getXMLHttpRequest(),loadJs(baseDir,jsList,cb),loadJsWithImg(baseDir,loadTxt(url,loadJson(url,loadImg(url,option,// 加载一张图片
	loadBinary(url,loadBinarySync(url),_loadResIterator(item,index,getUrl(basePath,url),load(resources,// 加载资源，然后回调
	loadAliases(url,// alias map
};

【字符串格式】
cc.formatStr()		// "a: %d,b: %b",a,b

【单例】
cc.director
cc.winSize
cc.view
cc.eventManager = cc.director.getEventDispatcher();
cc.audioEngine = cc.AudioEngine.getInstance();
cc.configuration = cc.Configuration.getInstance();

cc.textureCache = cc.director.getTextureCache();
cc.TextureCache.prototype.addImage = function(url,target)
cc.shaderCache = cc.ShaderCache.getInstance();
cc.animationCache
cc.spriteFrameCache
cc.plistParser = cc.PlistParser.getInstance();
cc.fileUtils = cc.FileUtils.getInstance();

【jsb】
jsb.fileUtils = cc.fileUtils;
delete cc.FileUtils;
delete cc.fileUtils;

// only android
jsb.reflection = {
    callStaticMethod : function(){
        cc.log("not supported on current platform");
    }
};

【sys】
cc._initSys(config,CONFIG_KEY)

cc._initDebugSetting(mode)
// cc.error,cc.assert(cond,msg),cc.warn,cc.log

【game】
cc.game = {
	setFrameRate,restart,run,// prepare -> onStart
	_initConfig,prepare			// 包含jsb.js及project.json里的js
};
