我有两个单元格的表格视图，单元格是 UIcollectionview，每个都认为在 Xcode 中工作正常，就在我从 Diawi 应用程序获得下载链接并在那里测试它时，主页上的应用程序崩溃
（带有收集单元的表格视图）
我的主页代码是：
class HomeVC: BaseVC ,UITableViewDelegate,UITableViewDataSource,ContinueLearningDelegate,HeaderViewLearnDelegate{
@IBOutlet weak var tableView:UITableView!
@IBOutlet weak var headerView:HeaderViewLearn!
@IBOutlet weak var headerHeightConstraint:NSLayoutConstraint!
private var homeStoriesViewModel:HomeStoriesViewModel?
var shouldAnimate = true
var selectedLevel = CLoginManager.shared.user?.level
var fetchDataInViewDidAppear = false
override func viewDidLoad() {
super.viewDidLoad()
registerCells()
fetchData()
}
fileprivate func registerCells(){
tableView.contentInset = UIEdgeInsets(top: 0, left: 0, bottom: 100, right: 0)
tableView.register(UINib(nibName: "CoursesDescTableViewCell", bundle: nil), forCellReuseIdentifier: CoursesDescTableViewCell.identifier)
tableView.register(UINib(nibName: "CoursesDataTableViewCell", bundle: nil), forCellReuseIdentifier: CoursesDataTableViewCell.identifier)
tableView.register(UINib(nibName: "ContinueLearningTableViewCell", bundle: nil), forCellReuseIdentifier: ContinueLearningTableViewCell.identifier)
tableView.dataSource = self
tableView.delegate = self
tableView.reloadData()
headerView.delegateSearchar = self
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
if indexPath.section == 0 {
if let cell = tableView.dequeueReusableCell(withIdentifier: ContinueLearningTableViewCell.identifier, for: indexPath) as? ContinueLearningTableViewCell {
cell.delegate = self
cell.configure(stories:(self.homeStoriesViewModel?.getStoriesBy(indexPath.section)) ?? [])
return cell
}
}
let cell = tableView.dequeueReusableCell(withIdentifier: CoursesDescTableViewCell.identifier, for: indexPath) as! CoursesDescTableViewCell
cell.delegate = self
cell.fromHome = true
return cell
}
// TableViewCell (homePage)
class ContinueLearningTableViewCell: UITableViewCell,UICollectionViewDelegate ,UICollectionViewDataSource{
static var identifier = "ContinueLearningTableViewCellIdentifier"
@IBOutlet weak var collectionView:UICollectionView!
weak var delegate:ContinueLearningDelegate?
var stories:[Story]?
override func awakeFromNib() {
registerCells()
setupCollectionLayout()
self.selectionStyle = .none
}
private func registerCells() {
collectionView.register(UINib(nibName: "CourseProfileCollectionViewCell", bundle: nil), forCellWithReuseIdentifier: CourseProfileCollectionViewCell.identifier)
}
private func setupCollectionLayout(){
let flowLayout: UICollectionViewFlowLayout = UICollectionViewFlowLayout()
let height = 320
flowLayout.itemSize = CGSize(width: (height), height: (height))
flowLayout.scrollDirection = .horizontal
flowLayout.minimumInteritemSpacing = 20
collectionView.collectionViewLayout = flowLayout
collectionView.delegate = self
collectionView.dataSource = self
}
func configure(stories:[Story]){
self.stories = stories
self.collectionView.reloadData()
}
func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
return stories?.count ?? 0
}
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: CourseProfileCollectionViewCell.identifier, for: indexPath) as! CourseProfileCollectionViewCell
if stories != nil {
cell.configure(story: stories![indexPath.item])
}
return cell
}
func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
if let cell = collectionView.cellForItem(at: indexPath) as? CourseProfileCollectionViewCell{
delegate?.onClickLessonStory(cell: cell,story:self.stories?[indexPath.item])
}
}
override func prepareForReuse() {
super.prepareForReuse()
}
}
the Log print :-
