        Try! this it works for me.
  CCSize screenSize   = CCDirector::sharedDirector()->getVisibleSize();
        pointOrigin  = CCDirector::sharedDirector()->getVisibleOrigin();
        x = screenSize.width;
        y = screenSize.height;


    CCSprite* sprite=CCSprite::create("icon.png");
        sprite->setPosition(ccp(x/2,y/2));
        addChild(sprite,1);
