UITableView 原型中带有图像的 UICollectionView 单元格
UICollectionView cells with Images inside UITableView prototype
更新：我解决了我的主要问题，即只有在 collectionView 上滚动才能加载正确的图像。我在 tableView:cellForRowAtIndexPath 中添加了 collectionView.reloadData()。我还进行了一些更改以预加载序列数组，而不是在滚动 table (tableView:cellForRowAtIndexPath).

一旦我弄清楚如何在 return 中放置动态值时防止应用程序崩溃（如果我将其设置为 15，应用程序将不会崩溃），我将跟进：
func collectionView(collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
return count(Array(sequenceArray[collectionView.tag])) / 2
}

请求一些指导。
本教程帮助我意识到这一定与我的 DataSource/Delegate 有关。作者使用 addSubview 构建单元格，而不是利用 Xcode 原型单元格，这似乎是一件很酷的事情，所以我正在尝试这样做。

欢迎对我的方法或未能遵循最佳实践提出任何批评。
table 中的每个单元格都有一个 UICollectionView。 Collection View 中的每个单元格都按照保存的“Sequence”字符串的顺序显示图像。示例：“ADKDQDJDTD”link 到 AD.png KD.png QD.png JD.png TD.png
我有两个问题似乎无法解决。
- numberOfItemsInSection gets whacky when the number of cards is driven by the array length (return handArray.count / 2). If I place a fixed number the app will work, but not very slick.
- When the table first comes up, the correct cards do not display until I scroll up and down the table. It also appears the data for each CollectionView is crossing paths as the wrong cards show up when scrolling up and down rapidly.
我几乎肯定这与我的数据源设置方式有关。

对于这个例子，我将 (return handArray.count / 2) 设置为 10 并加载了 3 个序列。

请注意，CollectionView 不会更新正确的卡片，它会从其他 CollectionView 中获取数据。如果我在这个组合中添加更多序列，当向上和向下滚动时，正确的卡片有时会填充，但 unpredictable.
感谢您的任何建议，我很高兴回到绘图板。干杯
好的，让我们这样想，您的 DeckTableViewController 充当表视图的数据源，DeckTableViewCell 充当集合视图的数据源。
考虑到以上内容，我们创建一个示例项目
我不会深入，我会在您完成
时给出教程之类的示例
让我们创建一个带有单视图应用程序的示例项目，并在 ViewController
通过下面的代码，我采用了一个整数数组，其中包含一些值作为要在集合视图中显示的单元格数。不要忘记添加 tableview 并设置其数据源和 deleagte。
在我们编码到控制器之前 class 我们需要一些 class 像自定义 tableview cell 和自定义 collection view cell 我们先创建它们
创建一个新文件，它是 UICollectionViewCell 的子 class 并将其命名为 CustomCollectionViewCell 并使用 xib 文件。
class CustomCollectionViewCell: UICollectionViewCell {
@IBOutlet weak var aLabel: UILabel! //to show the card number
@IBOutlet weak var imageView: UIImageView! //imageview i am setting it's background color
override init(frame: CGRect) {
super.init(frame: frame)
}
required init(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
}
override func awakeFromNib() {
super.awakeFromNib()
}
}
并像上面的代码一样为标签和图像视图创建一个出口。
接下来，创建 UITableViewCell 的新文件 subclass 并将其命名为 CustomTableViewCell 和 xib file。打开 CustomTableViewCell.xib 文件并拖放 collection view 并将其 datasource 和 delegate 设置为 cell 而不是控制器。
并为集合视图创建一个出口并将其命名为 foldersCollectionView。
通过以下代码
import UIKit
class CustomTableViewCell: UITableViewCell,UICollectionViewDataSource,UICollectionViewDelegate {
@IBOutlet weak var foldersCollectionView: UICollectionView!
override init(frame: CGRect) {
super.init(frame: frame)
}
required init(coder aDecoder: NSCoder) {
// fatalError("init(coder:) has not been implemented")
super.init(coder: aDecoder)
}
var folderCount:Int?
{
didSet(value)
{
}
}
override func awakeFromNib() {
super.awakeFromNib()
// Initialization code
//configure our collectionview
var aFlowLayout : UICollectionViewFlowLayout = UICollectionViewFlowLayout()
aFlowLayout.scrollDirection = UICollectionViewScrollDirection.Horizontal
aFlowLayout.itemSize = CGSizeMake(60.0, 90.0)
aFlowLayout.minimumLineSpacing = 10.0
aFlowLayout.minimumInteritemSpacing = 0.0
aFlowLayout.sectionInset = UIEdgeInsetsMake(2, 9, 0, 10)
foldersCollectionView.collectionViewLayout = aFlowLayout
foldersCollectionView.registerClass(CustomCollectionViewCell.self, forCellWithReuseIdentifier: "FOLDER_CELL")
var cNib:UINib? = UINib(nibName: "CustomCollectionViewCell", bundle: nil)
foldersCollectionView.registerNib(cNib, forCellWithReuseIdentifier: "FOLDER_CELL")
foldersCollectionView.frame = self.bounds
}
override func setSelected(selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
}
class func CreateCustomCell() -> CustomTableViewCell
{
var nibElements: Array = NSBundle.mainBundle().loadNibNamed("CustomTableViewCell", owner: self, options: nil)
var item: AnyObject?
for item in nibElements
{
if item is UITableViewCell
{
return item as CustomTableViewCell
}
}
return item as CustomTableViewCell
}
func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {
var cell :CustomCollectionViewCell? = collectionView.dequeueReusableCellWithReuseIdentifier("FOLDER_CELL", forIndexPath: indexPath) as? CustomCollectionViewCell
//hear u can modify which image to be displayed in the collection view cell
cell?.aLabel.text = "Card:\(indexPath.row)"
return cell!
}
func collectionView(collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
return folderCount!
}
func numberOfSectionsInCollectionView(collectionView: UICollectionView) -> Int {
return 1
}
}
现在我们将代码 ViewController class
现在刚刚通过下面的代码
class ViewController: UIViewController,UITableViewDataSource,UITableViewDelegate {
var cardCountArray:[Int] = []
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
cardCountArray = [5,15,6,12,7,10]
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func numberOfSectionsInTableView(tableView: UITableView) -> Int
{
return cardCountArray.count
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int
{
return 1
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell
{
var cell:CustomTableViewCell? = tableView.dequeueReusableCellWithIdentifier("CELL") as? CustomTableViewCell;
if(cell == nil)
{
cell = CustomTableViewCell.CreateCustomCell()
}
cell?.folderCount = cardCountArray[indexPath.section]
cell?.foldersCollectionView.reloadData()
cell?.clipsToBounds = true
return cell!;
}
func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat
{
return 100.0
}
func tableView(tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
var headerView:UIView = UIView(frame: CGRectMake(0, 0, tableView.bounds.size.width, 70.0))
var labelTitle:UILabel = UILabel(frame: CGRectMake(0, 0, tableView.bounds.size.width, 35))
var descriptionTitle:UILabel = UILabel(frame: CGRectMake(0, 20,tableView.bounds.size.width , 30))
headerView.addSubview(labelTitle)
headerView.addSubview(descriptionTitle)
labelTitle.text = "TOTAL_CARDS in section:\(section)"
descriptionTitle.text = "This CARD_SECTION contains \(cardCountArray[section]) CARDS"
return headerView
}
func tableView(tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
return 50.0
}
}
结果如下所示
如果有任何遗漏请告诉我
对于您的评论 我有一个数组，例如 ["2C3C4C5C6C7C", "AD2D3D4D5D", "9H8H7H"]
为此你需要做以下修改
//for first row u get like this

//cell?.folderCount = cardCountArray[indexPath.section]
cell?.stringForCell = stringArray[indexPath.section];
cell?.foldersCollectionView.reloadData()
cell?.clipsToBounds = true
return cell!;
}
//in custom tableview cell add a string variable
class CustomTableViewCell: UITableViewCell,UICollectionViewDataSource,UICollectionViewDelegate {
