Unity中NGUI上使用Scrollview

1. 添加ScrollView,注意ScrollView下面的depth和sortOrder

3. ScrollView下面添加Container，作为参考的父容器，主要是为了获取他的位置和大小，添加子控件然后设置位置。

var rank = LongJingRankModle.Instance.getMySelfRank(nowBtnSelect);
        ///////////////////////////////////        
        int  count = data.longJingRandInfos.Count;
        if(count>0)
        {            
            var flagCount = 0;
            for (var i = 0; i < count; i++)
            {
                if (flagCount == AllPlayerItems.Count)
                {
                    var cloneItem = Instantiate(bigPlayerItem);
                    cloneItem.transform.parent = Container.transform;
                    cloneItem.transform.localScale = Vector3.one;
                    cloneItem.transform.localEulerAngles = Vector3.zero;                    
                    AllPlayerItems.Add(cloneItem);
                }
                AllPlayerItems[flagCount].gameObject.SetActive(true);
                flagCount++;
            }
            int useNum = 0;
            for (var i = 0; i < data.longJingRandInfos.Count; i++)
            {

                // AllPlayerItems[i].InitItemData(i+1,data.longJingRandInfos[i].VipLevel,data.longJingRandInfos[i].NickName,data.longJingRandInfos[i].Point);
                AllPlayerItems[i].InitItemData(i,data.longJingRandInfos);
                AllPlayerItems[i].transform.localPosition = new Vector3(0, -(Container.height+5) * i, 0);
                print("i=========================" + i);
                AllPlayerItems[i].gameObject.SetActive(true);
                useNum++;
            }
            for (var i = useNum; i < AllPlayerItems.Count; i++)
            {
                AllPlayerItems[i].gameObject.SetActive(false);
            }
            ScrollView.gameObject.SetActive(true);
        }else
        {
            ScrollView.gameObject.SetActive(false);
        }

4.ScrollView上添加一个拖拽层panelDrag,

panelDrag是一个UIWidget 下面添加一个UIDragScrollView(拖拽)和BoxCollider(点击)

5．添加ScrollView下面的firstItem,添加子控件，添加UIDragScrollView和BoxCollider,添加完子控件后隐藏。
