cocos2d-x CC_SYNTHESIZE_READONLY

//定义一个只读属性Label，在类定义中可以使用this->getLabel来访问

     CC_SYNTHESIZE_READONLY(cocos2d::CCLabelTTF*,_label,Label);

CC_SYNTHESIZE_READONLY(varType, varName, funName)声明一个成员变量以及getfunName函数，没有set函数。getfunName已经实现，其实现就是返回这个值。

this ->_layer = GameOverLayer::node();

this ->_layer->retain();         

this ->addChild(_layer);

bool  GameOverLayer::init()

{

     if (CCLayerColor::initWithColor(ccc4(255,255,255,255)))

     {

         CCSize winSize = CCDirector::sharedDirector()->getWinSize();

         this ->_label = CCLabelTTF::labelWithString( "" , "Artial" ,32);

         this ->_label->retain();

         this ->_label->setColor(ccc3(0,0,0));

         this ->_label->setPosition(ccp(winSize.width/2,winSize.height/2));

         this ->addChild( this ->_label);

         this ->runAction(CCSequence::actions(CCDelayTime::actionWithDuration(3),

                                         CCCallFunc::actionWithTarget( this ,

                                         callfunc_selector(GameOverLayer::gameOverDone)),NULL));

         return  true ;

     }

     else

     {

         return  false ;
