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)))

{

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

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

this ->_label->retain();

this ->_label->setColor(ccc3(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 ;

}
