Cocos2d-x和处理触摸事件

我在屏幕上有我的精灵，我有一个存储每个精灵的向量。

CCSprite*能处理触摸事件吗？还是仅仅是CCLayer*？

决定哪个精灵被触摸的最佳方法是什么？我应该存储精灵所在位置的坐标（在精灵类中）吗？当我获得事件时，通过查看向量并获得每个精灵的当前坐标，看看用户触摸的位置是否就是精灵所在的位置？UPDATE：I子类CCSprite:

class Field : public cocos2d::CCSprite, public cocos2d::CCTargetedTouchDelegate

和我实现的功能：

    cocos2d::CCRect rect();
    virtual void onEnter();
    virtual void onExit();
    bool containsTouchLocation(cocos2d::CCTouch* touch);
    virtual bool ccTouchBegan(cocos2d::CCTouch* touch, cocos2d::CCEvent* event);
    virtual void ccTouchMoved(cocos2d::CCTouch* touch, cocos2d::CCEvent* event);
    virtual void ccTouchEnded(cocos2d::CCTouch* touch, cocos2d::CCEvent* event);
    virtual void touchDelegateRetain();
    virtual void touchDelegateRelease();

我把CCLOG语句放在每一个语句中，我没有命中它们！

当我触摸CCLayer时，这个精灵是打开的，尽管我确实击中了实现Layer的类中的那些精灵，并将这些精灵放在层上。

更新：我一直在尝试的代码：

Field* Field::createWithLocation(cocos2d::CCPoint p)
{
    Field* f = new Field();
    f->autorelease();
    f->initWithLocation(p);
    return f;
}
void Field::initWithLocation(cocos2d::CCPoint p)
{
    setFieldCenterPoint(p);
    setFieldGraphicName(FIELD::fieldIconFileName);
    setFieldSprite(cocos2d::CCSprite::create(getFieldGraphicName().c_str()));
    getFieldSprite()->setPosition(ccp(getFieldCenterPoint().x, getFieldCenterPoint().y));
    setFieldSize(getFieldSprite()->getContentSize());
}
cocos2d::CCRect Field::rect()
{
    cocos2d::CCSize s = getFieldSprite()->getTexture()->getContentSize();
    return cocos2d::CCRectMake(-s.width / 2, -s.height / 2, s.width, s.height);
}
void Field::onEnter()
{
    CCLOG("In onEnter");
    cocos2d::CCDirector* pDirector = cocos2d::CCDirector::sharedDirector();
    pDirector->getTouchDispatcher()->addTargetedDelegate(this, 0, true);
    //_dir->Instance()->getDirector()->getTouchDispatcher()->addTargetedDelegate(this, 0, true);
    cocos2d::CCSprite::onEnter();
}
void Field::onExit()
{
    CCLOG("In onExit");
    cocos2d::CCDirector* pDirector = cocos2d::CCDirector::sharedDirector();
    pDirector->getTouchDispatcher()->removeDelegate(this);
    //_dir->Instance()->getDirector()->getTouchDispatcher()->removeDelegate(this);
    cocos2d::CCSprite::onExit();
}
bool Field::containsTouchLocation(cocos2d::CCTouch* touch)
{
    return rect().containsPoint(convertTouchToNodeSpaceAR(touch));
}
bool Field::ccTouchBegan(cocos2d::CCTouch* touch, cocos2d::CCEvent* event)
{
    CCLOG("In ccTouchBegan");
    return true;
}
void Field::ccTouchMoved(cocos2d::CCTouch* touch, cocos2d::CCEvent* event)
{
    CCLOG("In ccTouchMoved");
}
void Field::ccTouchEnded(cocos2d::CCTouch* touch, cocos2d::CCEvent* event)
{
     CCLOG("In ccTouchEnded");
}
void Field::touchDelegateRetain()
{
    this->retain();
}
void Field::touchDelegateRelease()
{
    this->release();
}
