【已解决】v2.1.4f版本的UIScrollView不能回弹

Studio
#1

贴出i代码，大家帮忙哪里出现的问题。
版本：v2.1.4f（我听说G版本才取消回弹效果，这个版本应该有吧）控件：UIScrollView
代码：
] UILayer uly = UILayer::create();
] uly->setContentSize(ccp(480,320));
] this->addChild(uly,100,100);
]
] UIScrollView usv = UIScrollView::create();
] usv->setBackGroundImage(“scrollviewbg.png”);
] usv->setClippingEnable(true);
] usv->setUpdateEnable(true);
] usv->setPosition(ccp(0,0));
] usv->setTouchEnable(true);
] //
] / SCROLLVIEW_DIR_NONE,
] SCROLLVIEW_DIR_VERTICAL,
] SCROLLVIEW_DIR_HORIZONTAL /
] //
] usv->setDirection(SCROLLVIEW_DIR_VERTICAL);
] //
] / SCROLLVIEW_MOVE_MODE_NONE,
] SCROLLVIEW_MOVE_MODE_NORMAL,
] SCROLLVIEW_MOVE_MODE_ACTION /
] /***/
*] usv->setMoveMode(SCROLLVIEW_MOVE_MODE_ACTION);
*]
*]
*] usv->setSize(ccp(92,90));
*] uly->addWidget(usv);
*]
*] for (int i =0;i<15;i++)
*] {
] UILabel ulb = UILabel::create();
] ulb->setPosition(ccp(20,90-i25));
*] ulb->setText(“UILABELxxxx”);
*] ulb->setFontName(“黑体”);
*] ulb->setFontSize(24);
*] usv->addChild(ulb);
*] }

太详细了,太感谢了

还在研究,因为我用的是2.1.4h回弹的处理在这个版本上都干掉了.

你指的回弹效果是什么啊？是指拉过头了后往回移的效果吗？

如果确实是指这个的话，你又不嫌弃的话可以到C …

UIScrollView回弹的问题什么时候能发布啊,急用

你指的回弹效果是什么啊？是指拉过头了后往回移的效果吗？

如果确实是指这个的话，你又不嫌弃的话可以到Cocos2dx_v2.1.4fextensionsCocoGUILIBUIWidgetsUIScrollView.cpp里面，把resetPositionWithAction函数换成下面这个，然后再在berthChildren函数的开头加个return;（如果是垂直拉的，内容较少时会靠在上面；水平拉时靠在左边）

void UIScrollView::resetPositionWithAction()
{
    using namespace cocos2d;
    CCPoint delta = CCPointZero;
    UIWidget* child = getCheckPositionChild();
	UIWidget* topChild;
	UIWidget* bottomChild;
	float targetPosition;
	topChild = dynamic_cast<UIWidget*>(m_children->objectAtIndex(0));
	bottomChild = dynamic_cast<UIWidget*>(m_children->lastObject());
    switch (m_eDirection)
    {
        case SCROLLVIEW_DIR_VERTICAL: // vertical
            switch (m_eMoveDirection)
            {
				
                case SCROLLVIEW_MOVE_DIR_UP: // up
					targetPosition = max(m_fBottomBoundary + m_fDisBoundaryToChild_0 + topChild->getRelativeTopPos() - bottomChild->getRelativeBottomPos(), 
										 m_fTopBoundary - m_fDisBoundaryToChild_0); 	
					delta.y = targetPosition - topChild->getRelativeTopPos();
                    break;
                    
                case SCROLLVIEW_MOVE_DIR_DOWN: // down
					targetPosition = m_fTopBoundary - m_fDisBoundaryToChild_0;
                    delta.y = targetPosition - topChild->getRelativeTopPos();
					break;

                default:
                    break;
            }
            break;
        case SCROLLVIEW_DIR_HORIZONTAL: // horizontal
            switch (m_eMoveDirection)
            {
                case SCROLLVIEW_MOVE_DIR_LEFT: // left
					targetPosition = min(m_fLeftBoundary + m_fDisBoundaryToChild_0,
										 m_fRightBoundary - m_fDisBoundaryToChild_0 + topChild->getRelativeLeftPos() - bottomChild->getRelativeRightPos());
                    delta.x = targetPosition - topChild->getRelativeLeftPos();
                    break;
                    
                case SCROLLVIEW_MOVE_DIR_RIGHT: // right
					targetPosition = m_fLeftBoundary + m_fDisBoundaryToChild_0;
                    delta.x = targetPosition - topChild->getRelativeLeftPos(); 
                    break;
                default:
                    break;
            }
            break;
        default:
            break;
    }
    
//    int times = m_children->count();
    ccArray* arrayChildren = m_children->data;
    int times = arrayChildren->num;
    for (int i = 0; i < times - 1; ++i)
    {
        UIWidget* child = dynamic_cast<UIWidget*>(arrayChildren->arr*);
        CCMoveBy* moveBy = CCMoveBy::create(0.25, delta);
        CCEaseOut* ease = CCEaseOut::create(moveBy, 0.5);
        child->runAction(ease);
    }
    
    UIWidget* child_last = dynamic_cast<UIWidget*>(m_children->lastObject());
    CCMoveBy* moveBy = CCMoveBy::create(0.25, delta);
    CCEaseOut* ease = CCEaseOut::create(moveBy, 0.5);
    CCCallFunc* callFunc = CCCallFunc::create(this, callfunc_selector(UIScrollView::handleScrollActionEvent));
    CCSequence* seq = CCSequence::create(ease, callFunc, NULL);
    child_last->runAction(seq);
    
    isRunningAction = true;
}
*垂直移动时，图片要从上往下加；水平移动时，图片要从左往右加。
急用的话可以尝试下这个（我也是急用才自己改的）。不然还是耐心等官方发布吧。

建议楼主不要使用，回弹模式因为存在 bug，所以 g 版之后已经取消了
