cocos2d-x中CCScrollView纵向展示

最近写CCScrollView遇到很多问题，样式是竖直的类似tableview，在此记录下:

 CCLayer* layer; 　　

初始化scrollview内容器层

 layer = CCLayer::create();

设置layer

 layer->setPosition(ccp(, -));

初始化CCScrollView

     scrollView=CCScrollView::create(CCSizeMake(, --));
     scrollView->setPosition(ccp(,));
     scrollView->setDelegate(this);
     this->addChild(scrollView);
     scrollView->setContainer(layer);
     scrollView->setContentSize(CCSizeMake(, -));
     scrollView->setDirection(kCCScrollViewDirectionVertical);
     scrollView->setTouchEnabled(false);

校对和调整回滚

 bool HandbookManager::ccTouchBegan( CCTouch *pTouch, CCEvent *pEvent )
 {
     CCPoint startPos = pTouch->getLocation(); 

     return true;
 }

 void HandbookManager::ccTouchMoved( CCTouch *pTouch, CCEvent *pEvent )
 {
     CCPoint currPos = pTouch->getLocation();
     CCPoint prevPos = pTouch->getPreviousLocation();

     CCLayer * info_listbg = (CCLayer*)scrollView->getContainer();

     if(scrollView->boundingBox().containsPoint(currPos))
     {
         float y = info_listbg->getPositionY();
         info_listbg->setPositionY(y+currPos.y-prevPos.y);
     }
 }

 void HandbookManager::ccTouchEnded( CCTouch *pTouch, CCEvent *pEvent )
 {
     CCPoint touchPoint = convertTouchToNodeSpace(pTouch);
     touchPoint = ccpAdd(this->getPosition(), touchPoint);
     float dx=fabs(pTouch->getStartLocation().x-pTouch->getLocation().x);
     float dy=fabs(pTouch->getStartLocation().y-pTouch->getLocation().y);

     if(dx< && dy<){
         this->touchPoint(touchPoint);
     }

     CCSprite * s1 = (CCSprite*)layer->getChildByTag();//取出层上最上精灵元素
     CCSprite * s2 = (CCSprite*)layer->getChildByTag(flagTag);//取出层上最下精灵元素元素

         p1.y -=  - layer->getPositionY();
         p2.y -=  - layer->getPositionY()+;

     //firstSpritePosition为层上最上面元素的position
     //lastSpritePosition 为层上最下面元素的position

     float y1 = firstSpritePosition.y;
     float y2;
     if(lastSpritePosition.y>firstSpritePosition.y-scrollView->boundingBox().size.height)
         y2 = lastSpritePosition.y;
     else
         y2 = firstSpritePosition.y-scrollView->boundingBox().size.height;

     if(p1.y <= y1){
         CCActionInterval * action = CCMoveBy::create((y1-p1.y)/,ccp(,y1-p1.y));
         layer->runAction(action);
     }
     if(p2.y >= y2){

         CCActionInterval * action = CCMoveBy::create((p2.y-y2)/,ccp(,y2-p2.y));
         layer->runAction(action);

     }
 }

//取得scrollview中点击区域

 CCRect HandbookManager::getRect(CCNode * pNode)
 {
     CCRect rc;
     rc.origin = pNode->getPosition();
     rc.size =  pNode->boundingBox().size;
     rc.origin.x -= rc.size.width*0.5 - layer->getPositionX();
     rc.origin.y -= rc.size.height*0.5- layer->getPositionY();

     rc.origin.x += ;
     rc.origin.y += ;
     return rc;
 }
