9. cocos2dx 判断点是否在框内

1：Node的通用方法

if(pItem->boundingBox().containsPoint(point))
{
   //do sth
}

2：other way

CCPoint pos = this->getPosition();
CCSize size = this->getContentSize();
CCRect rect(pos.x, pos.y, size.width, size.height);

if( CCRect::CCRectContainsPoint(rect, point)  )
{
    //do sth
}
