我的public void createFolder(ListsSoap ls, String filePathToCreate, String fileName, LoginDO loginDO, HttpServletResponse response) throws Exception { try { String query = ""; String folderName = "NewFolder"; // 1. Prepare Query, Query Options and field Options if (CommonUtilities.isValidStr(folderName)) { // Prepare Query & Query Options for child folders



            query = "<Batch OnError=\"Continue\" PreCalc=\"TRUE\" ListVersion=\"0\" " +
                    "RootFolder=\"https://xxx/Shared%20Documents/FPL%20SOs%20-%20JD%20Documents\">"
                    + "<Method ID=\"1\" Cmd=\"New\">"
                    + "<Field Name=\"FSObjType\">1</Field>"
                    +"<Field Name=\"ID\">New</Field>"
                    + "<Field Name=\"BaseName\">" + folderName + "</Field>"
                    + "</Method></Batch>";
        } else {
            // Prepare Query & Query Options for Parent folders

            query = "<Query><Where><Eq><FieldRef Name=\"FSObjType\" />"
                    + "<Value Type=\"Lookup\">1</Value></Eq></Where></Query>";

        }

        UpdateListItems.Updates updates = null;

        // 2. Prepare Query, QueryOptions & ViewFields object as per options
        if (CommonUtilities.isValidStr(query)) {
            updates = new UpdateListItems.Updates();
            updates.getContent().add(
                    sharepointUtil.createSharePointCAMLNode(query));
        }

        // 3. Call Web service to get result for selected options
        UpdateListItemsResult result = ls
                .updateListItems(SHAREPOINT_FOLDER_NAME,updates);

        /*

        Element element = (Element) result.getContent().get(0);
        NodeList nl = element.getElementsByTagName("z:row");
        for (int i = 0; i < nl.getLength(); i++) {
            Node node = nl.item(i);
            System.out.println("Some.!");

        }
    } catch (Exception e) {
        e.printStackTrace();
    }
    // logger.logMethodEnd();
}`

具有相同的单元格类型，但每个单元格都有不同的UI属性，例如UICollectionView，background color ......

我可以在textColor内配置它们，如下所示：

collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell

正如您从案例1到5中可以看到具有不同UI属性的相同单元格类型，它根本没有吸引力，也不具有可伸缩性，因此处理此类配置的最佳方法是什么？

Answer 1

您需要将数据保存在内存中，因此由于UICollectionViewCell的可重用性，您必须存储单元格的配置。

let dictForCell = ["color":UIColor.redColor(),"isHidden":false] //add key value according to your need
let arrOfCell   = [dictForCell] //also add dictionary of detail

func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
    let dictData = [indexPath.row]
        let cell = collectionView.dequeueReusableCell(forIndexPath: indexPath) as ACollectionViewCell  
        cell.ScoreName.textColor = dictData["color"] as! UIColor
        cell.score.isHidden = dictData["color"] as! Bool        
        cell.score.text = xxx
        cell.score.backgroundColor = xxx
        cell.ScoreName.text = xxx
        return cell
    }

Answer 2

背景颜色，textColor等应作为变量添加到用于填充该集合视图的对象中。每个对象都有自己的变量，用于自定义单元格。
