Ios tableViewCell数据显示中的CollectionView

我在每个tableViewCell中嵌入了collectionView。在每个tableViewWillDisplayCell事件上，我为collectionView设置了正确的数据源，然后在collectionView中重新加载数据

代码如下：

override func tableView(tableView: UITableView, willDisplayCell cell: UITableViewCell, forRowAtIndexPath indexPath: NSIndexPath) {
    let c = cell as! CustomTableViewCell
    c.setCollectionViewDataSourceDelegate(dataSourceDelegate: self, indexPath: indexPath)
}

CustomTableViewCell.swift：

class CustomTableViewCell: UITableViewCell {

var collectionView: indexedCollectionView!

override init(style: UITableViewCellStyle, reuseIdentifier: String?) {
    super.init(style: style, reuseIdentifier: reuseIdentifier)

    var layout: UICollectionViewFlowLayout = UICollectionViewFlowLayout()
    layout.sectionInset = UIEdgeInsets(top: 5, left: 5, bottom: 5, right: 5)
    layout.itemSize = CGSizeMake(5, 5)
    layout.scrollDirection = UICollectionViewScrollDirection.Horizontal
    self.collectionView = indexedCollectionView(frame: CGRectZero, collectionViewLayout: layout)
    self.collectionView.registerClass(UICollectionViewCell.classForCoder(), forCellWithReuseIdentifier: collectionViewCellIdentifier as String)
    self.collectionView.backgroundColor = UIColor.whiteColor()
    self.collectionView.showsHorizontalScrollIndicator = false
    self.contentView.addSubview(self.collectionView)
}

required init(coder aDecoder: NSCoder) {
    super.init(coder: aDecoder)
}

override func layoutSubviews() {
    super.layoutSubviews()
    self.collectionView.frame = self.contentView.bounds;
}

func setCollectionViewDataSourceDelegate(dataSourceDelegate delegate: protocol<UICollectionViewDelegate,UICollectionViewDataSource>, indexPath: NSIndexPath){
    self.collectionView.dataSource = delegate
    self.collectionView.delegate = delegate
    self.collectionView.indexPath = indexPath
    self.collectionView.tag = indexPath.row
    self.collectionView.reloadData()
}

}

class CustomTableViewCell: UITableViewCell, UICollectionViewDataSource, UICollectionViewDelegate {

//var collectionView: UICollectionView!
@IBOutlet weak var collectionView: UICollectionView!

var event: Event?
var size: CGSize?

override func awakeFromNib() {
    super.awakeFromNib()
    println("awake")

    var layout: UICollectionViewFlowLayout = UICollectionViewFlowLayout()
    layout.sectionInset = UIEdgeInsets(top: 5, left: 5, bottom: 5, right: 5)
    layout.itemSize = CGSizeMake(5, 5)
    layout.scrollDirection = UICollectionViewScrollDirection.Horizontal
    collectionView.collectionViewLayout = layout
    //self.collectionView = indexedCollectionView(frame: CGRectZero, collectionViewLayout: layout)
    collectionView.registerClass(CustomCollectionViewCell.self, forCellWithReuseIdentifier: "CollectionViewCell")
    collectionView.backgroundColor = UIColor.whiteColor()
    collectionView.showsHorizontalScrollIndicator = false
    var cNib:UINib? = UINib(nibName: "CustomCollectionViewCell", bundle: nil)

当应用程序启动时，一切看起来都很好（），但当我滚动我的tableView时，触发tableView将再次为触发collectionView的重新加载数据的每个单元格显示cell事件

但是效果不好（）。有人能帮我解决我的问题吗

更新：

我试图重新编写代码，但遇到了一个问题。这是我的全部代码：

class TableViewController: UITableViewController {//, UICollectionViewDataSource, UICollectionViewDelegate {

var events: [Event] = [
    Event(category: "GAA - Football Campionship", event: "Round 4A Munster Final Runner up v Round 3A Winner", location: "Semple Stadium - Thurles", date: "7/12/15", time: "2:00pm"),
    Event(category: "Football", event: "Round 4A Munster", location: "Thurles", date: "7/2/15", time: "All day"),
    Event(category: "Golf - 4 Majors", event: "U.S. Open Day 4 ( Final Day)", location: "Oakmont Country Club, Pennsylvania", date: "7/12/15", time: ""),
]

override func viewDidLoad() {
    super.viewDidLoad()

    //self.tableView.registerClass(CustomTableViewCell.self, forCellReuseIdentifier: "Cell")
    self.tableView.separatorStyle = .None
    self.tableView.tableFooterView = UIView(frame: CGRectZero)
}

// MARK: - Table view data source

override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
    return 1
}

override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return events.count
}

override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    var cell: CustomTableViewCell? = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as? CustomTableViewCell

    if cell == nil {
        cell = CustomTableViewCell.CreateCustomCell()
    }
    cell!.event = events[indexPath.row]
    cell!.size = CGSize(width: cell!.frame.width, height: cell!.frame.height)
    cell!.collectionView.reloadData()
    cell!.clipsToBounds = true

    return cell!
}

//    override func tableView(tableView: UITableView, willDisplayCell cell: UITableViewCell, forRowAtIndexPath indexPath: NSIndexPath) {
//        let c = cell as! CustomTableViewCell
//        c.setCollectionViewDataSourceDelegate(dataSourceDelegate: self, indexPath: indexPath)
//    }

override func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {
    var cellHeight: CGFloat = 0.0
    let screenWidth: CGFloat = UIScreen.mainScreen().bounds.width

    var question: NSString = events[indexPath.row].category
    var size = CGSizeMake(screenWidth * 0.2, 9999)
    var textRect = question.boundingRectWithSize(size, options: NSStringDrawingOptions.UsesLineFragmentOrigin, attributes: [NSFontAttributeName: UIFont(name: "HelveticaNeue-Light", size: 18.0)!], context: nil)
    size = textRect.size
    cellHeight = size.height

    question = events[indexPath.row].event
    size = CGSizeMake(screenWidth * 0.3, 9999)
    textRect = question.boundingRectWithSize(size, options: NSStringDrawingOptions.UsesLineFragmentOrigin, attributes: [NSFontAttributeName: UIFont(name: "HelveticaNeue-Light", size: 18.0)!], context: nil)
    size = textRect.size
    if cellHeight < size.height {
        cellHeight = size.height
    }

    question = events[indexPath.row].location
    size = CGSizeMake(screenWidth * 0.3, 9999)
    textRect = question.boundingRectWithSize(size, options: NSStringDrawingOptions.UsesLineFragmentOrigin, attributes: [NSFontAttributeName: UIFont(name: "HelveticaNeue-Light", size: 18.0)!], context: nil)
    size = textRect.size
    if cellHeight < size.height {
        cellHeight = size.height
    }

    question = events[indexPath.row].date
    size = CGSizeMake(screenWidth * 0.1, 9999)
    textRect = question.boundingRectWithSize(size, options: NSStringDrawingOptions.UsesLineFragmentOrigin, attributes: [NSFontAttributeName: UIFont(name: "HelveticaNeue-Light", size: 18.0)!], context: nil)
    size = textRect.size
    if cellHeight < size.height {
        cellHeight = size.height
    }

    question = events[indexPath.row].time
    size = CGSizeMake(screenWidth * 0.1, 9999)
    textRect = question.boundingRectWithSize(size, options: NSStringDrawingOptions.UsesLineFragmentOrigin, attributes: [NSFontAttributeName: UIFont(name: "HelveticaNeue-Light", size: 18.0)!], context: nil)
    size = textRect.size
    if cellHeight < size.height {
        cellHeight = size.height
    }

    return cellHeight
}
}

此外，在故事板中，我向tableViewCell添加了一个collectionView，将其连接到outlet变量，并将CustomCollectionCell类设置为故事板中的collectionCell

但当我启动应用程序时，它在TableViewCellForRowatineXpath的这一行抛出了一个异常：

2015-07-16 13:29:00.965 CollectionViewInTableViewCell[4241:1005396]由于未捕获的异常NSUnknownKeyException而终止应用程序，原因：[CollectionViewInTableViewCell.CustomTableViewCell 0x126e12440 setValue:forUndefinedKey:]：此类不符合密钥集合的键值编码。'

您的

CustomTableViewCell

必须实现

UICollectionViewDelegate

和

UICollectionViewDataSource

，在将单元格添加到表视图时，单元格本身必须链接到委派和数据源。

检查我的答案听到我如何将数据从控制器传递到customTableViewCell以向collectionViewCells输入数据？只需向您的单元格添加数据属性即可自定义单元格并在控制器（CellForRowatineXpath）中进行设置。好的，我将尝试并告诉您是否出现问题。@mikle94在我的示例代码中，在

cellForAtIndexPath

方法中，我将数据传递给单元格，在单元格中，它将由集合视图使用，例如

cell？.folderCount=cardCountArray[indexPath.section]
