四、触摸处理ccTouchEnded()流程
1、获取触摸屏幕的坐标转换成地图坐标
2、推断该是否在有效范围、是否为空
3、播放触摸声音
4、依据点击坐标获取精灵、并放大1.3倍
5、依据坐标获取前一个点击的精灵
6、比較这两精灵能否够连接消除
  是。播放消除声音，清除这两坐标node。隐藏这两精灵
  否，缩小前一个精灵，并有抖动动画
7、把当前点击坐标赋值于前一个坐标. (前一坐标初始值(-1, -1))

	location = this->convertToNodeSpace(location);
    
    //location=CCPointMake(location.x, location.y-40);
    
    location=this->pointOfView(location);
    
    
      CCLOG("x:%f",location.x);
      CCLOG("y:%f",location.y);

    if (this->isValiableNode(location)==false)
    {
        return;
    }
    
    if (this->isEmptyNode(location))
    {
        return;
    }

    

    SimpleAudioEngine::sharedEngine()->playEffect("12.wav"); //触摸声音
    
    
    
    if (this->isSamePoints(location, prePoint))
    {
        return;
    }
    
    //点击当前精灵
    CCSprite *spritecurrent=(CCSprite *)this->getChildByTag(TAG_START_SPRITE+this->indexFromPoint(location));
    spritecurrent->setScale(1.3); //放大
