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:

1 CCLayer* layer; 　　

初始化scrollview内容器层

1 layer = CCLayer::create();

设置layer

1 layer->setPosition(ccp(0, -116));

初始化CCScrollView

1     scrollView=CCScrollView::create(CCSizeMake(640, 960-116-160));
2     scrollView->setPosition(ccp(0,116));
3     scrollView->setDelegate(this);
4     this->addChild(scrollView);
5     scrollView->setContainer(layer);
6     scrollView->setContentSize(CCSizeMake(640, 960-160));
7     scrollView->setDirection(kCCScrollViewDirectionVertical);
8     scrollView->setTouchEnabled(false);

校对和调整回滚

 1 bool HandbookManager::ccTouchBegan( CCTouch *pTouch, CCEvent *pEvent )
 2 {
 3     CCPoint startPos = pTouch->getLocation(); 
 4     
 5     return true;
 6 }
 7 
 8 void HandbookManager::ccTouchMoved( CCTouch *pTouch, CCEvent *pEvent )
 9 {
10     CCPoint currPos = pTouch->getLocation();
11     CCPoint prevPos = pTouch->getPreviousLocation();
12     
13     CCLayer * info_listbg = (CCLayer*)scrollView->getContainer();
14     
15     if(scrollView->boundingBox().containsPoint(currPos))
16     {
17         float y = info_listbg->getPositionY();
18         info_listbg->setPositionY(y+currPos.y-prevPos.y);
19     }
20 }
21 
22 void HandbookManager::ccTouchEnded( CCTouch *pTouch, CCEvent *pEvent )
23 {
24     CCPoint touchPoint = convertTouchToNodeSpace(pTouch);
25     touchPoint = ccpAdd(this->getPosition(), touchPoint);
26     float dx=fabs(pTouch->getStartLocation().x-pTouch->getLocation().x);
27     float dy=fabs(pTouch->getStartLocation().y-pTouch->getLocation().y);
28     
29     if(dx<5 && dy<5){
30         this->touchPoint(touchPoint);
31     }
32     
33     
34     CCSprite * s1 = (CCSprite*)layer->getChildByTag(0);//取出层上最上精灵元素
35     CCSprite * s2 = (CCSprite*)layer->getChildByTag(flagTag);//取出层上最下精灵元素元素
36     
37 
38         p1.y -=  0- layer->getPositionY();
39         p2.y -=  0- layer->getPositionY()+;
40 
41     //firstSpritePosition为层上最上面元素的position
42     //lastSpritePosition 为层上最下面元素的position
43     
44     float y1 = firstSpritePosition.y;
45     float y2;
46     if(lastSpritePosition.y>firstSpritePosition.y-scrollView->boundingBox().size.height)
47         y2 = lastSpritePosition.y;
48     else
49         y2 = firstSpritePosition.y-scrollView->boundingBox().size.height;
50     
51     if(p1.y <= y1){
52         CCActionInterval * action = CCMoveBy::create((y1-p1.y)/700,ccp(0,y1-p1.y));
53         layer->runAction(action);
54     }
55     if(p2.y >= y2){
56         
57         CCActionInterval * action = CCMoveBy::create((p2.y-y2)/700,ccp(0,y2-p2.y));
58         layer->runAction(action);
59         
60     }
61 }

//取得scrollview中点击区域

 1 CCRect HandbookManager::getRect(CCNode * pNode)
 2 {
 3     CCRect rc;
 4     rc.origin = pNode->getPosition();
 5     rc.size =  pNode->boundingBox().size;
 6     rc.origin.x -= rc.size.width*0.5 - layer->getPositionX();
 7     rc.origin.y -= rc.size.height*0.5- layer->getPositionY();
 8     
 9     rc.origin.x += 0;
10     rc.origin.y += 116;
11     return rc;
12 }
