Question

我尝试使用UICollectionView将不同的单元格绑定到XIB文件并为其设置设计。

我知道如何绑定不同的单元格，它在我的应用程序中运行良好。

这里是要绑定的代码：

override func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {

    var cell : UICollectionViewCell
    mCurrentIndexPath = indexPath

    // HEADER
    switch indexPath.section {
    case 0:
        cell = configureModuleHeaderCell(indexPath)
    default:
        // Local
        let theme = getThemeFromIndex(indexPath.section - 1)
        mCurrentDocuments = getDocumentsFromTheme(theme)
        let cours : DownloadableDocument? = (mCurrentDocuments != nil) ? getCoursForTheme() : nil
        mCurrentDocuments = deleteCoursFromDocAnnexe()
        mCurrentDocuments = sortDocumentDoublePDF()
        if indexPath.row == 0 {
            cell = configureThemeHeaderCell(theme, cours: cours)
        }

            // NORMAL
        else {
            cell = configureThemeDocCell()
            cell.layer.borderWidth = 1.0
            cell.layer.borderColor = UIColor.grayColor().CGColor
        }
        break
    }

    return cell
}

override func numberOfSectionsInCollectionView(collectionView: UICollectionView) -> Int {
    if mFetchedResultController != nil {
        mCurrentIndexPath = NSIndexPath(forRow: 0, inSection: 0)
        return mFetchedResultController!.fetchedObjects!.count + 1
    }
    return 0
}

override func collectionView(collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
    var counter : Int = 1
    switch section {
    case 0:
        counter = 1
        break
    default:
        mCurrentDocuments = getDocumentsFromTheme(getThemeFromIndex(section - 1))
        mCurrentDocuments = checkDoubleCours()
        counter = (mCurrentDocuments != nil) ? mCurrentDocuments!.count : 0
        counter += (!documentsContainsCours(mCurrentDocuments)) ? 1 : 0
        break
    }
    return counter
}

然后我想为每个 border 设置section。这可能吗？

我可以通过以下方式为单元格设置边框：

cell.layer.borderWidth = 1.0
cell.layer.borderColor = UIColor.grayColor().CGColor

但我想为section。

做这件事

我终于找到了解决方案！

我只需要计算一个部分的所有单元格的高度，在视图上设置这个高度并将其定位好。

修改更新@Urmi

添加此功能以使用框架
实例化cardView
func instanciateCardView(frame : CGRect) -> UIView { // Declaration let view = UIView(frame : frame) // Basic UI view.backgroundColor = UIColor.whiteColor() view.layer.backgroundColor = UIColor.whiteColor().CGColor view.layer.borderWidth = 1.0 view.layer.borderColor = ColorsUtil.UIColorFromRGB(0xAB9595).CGColor // Shadow (cardview style) view.layer.shadowPath = UIBezierPath(rect: view.bounds).CGPath view.layer.shouldRasterize = true view.layer.shadowColor = ColorsUtil.UIColorFromRGB(0xD5C6C6).CGColor view.layer.shadowOpacity = 1 view.layer.shadowOffset = CGSizeMake(1, 1); view.layer.shadowRadius = 1.0 if !mCardViewList.contains(view) { // Add view to container - Just to save the instance mCardViewList.append(view) // Add view to main view self.collectionView?.addSubview(view) self.collectionView?.sendSubviewToBack(view) } return view }

在cellForItemAtIndexPath：

override func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell { var cell : UICollectionViewCell mCurrentIndexPath = indexPath switch indexPath.section { case 0: cell = configureModuleHeaderCell(indexPath) // Basic UI cell.backgroundColor = UIColor.whiteColor() cell.layer.borderWidth = 1.0 cell.layer.borderColor = ColorsUtil.UIColorFromRGB(0xAB9595).CGColor // Shadow (cardview style) cell.layer.shadowPath = UIBezierPath(rect: view.bounds).CGPath cell.layer.shouldRasterize = true cell.layer.shadowColor = ColorsUtil.UIColorFromRGB(0xD5C6C6).CGColor cell.layer.shadowOpacity = 1 cell.layer.shadowOffset = CGSizeMake(1, 1); cell.layer.shadowRadius = 1.0 break default: let theme = getThemeFromIndex(indexPath.section - 1) mCurrentDocuments = getDocumentsFromTheme(theme) let cours : DownloadableDocument? = (mCurrentDocuments != nil) ? getCoursForTheme() : nil mCurrentDocuments = deleteCoursFromDocAnnexe() mCurrentDocuments = sortDocumentDoublePDF(mCurrentDocuments) if indexPath.row == 0 { cell = configureThemeHeaderCell(theme, cours: cours) if mCurrentDocuments != nil { if mCurrentDocuments!.count == 0 { instanciateCardView(CGRectMake(cell.frame.origin.x - 30, cell.frame.origin.y - 10, cell.frame.width + 60, cell.frame.height + 20)) } } } else { cell = configureThemeDocCell() if indexPath.row == mCollectionView.numberOfItemsInSection(indexPath.section) - 1 { // Attribute let index = NSIndexPath(forRow: 0, inSection: indexPath.section) let headerAttribute : UICollectionViewLayoutAttributes = mCollectionView.layoutAttributesForItemAtIndexPath(index)! let height = (cell.frame.origin.y + cell.frame.height) - (headerAttribute.frame.origin.y - 10) instanciateCardView(CGRectMake(headerAttribute.frame.origin.x - 30, headerAttribute.frame.origin.y - 10, headerAttribute.frame.width + 60, height + 20)) } } break } return cell }

我发现不是最佳解决方案，但它确实有效。现在我宣布UITableView并在每个UICollectionView
中添加UITableViewCell
