我有collectionView内部tableView。 collectionView需要水平滚动图像,tableView垂直滚动的帖子。当我有3 行我没有问题,但是当我创建4 行我有滚动项内部行的问题。如果我开始滚动的行,滚动重复行 1,同样的事情,如果我开始滚动1个行滚动重复上行 4.滚动时重复使用内部项目
可能是什么问题,如何解决它?可能是
可以检查.gif文件。我开始 1个行的名称为“尾子”如果我在行向下滚动和向右滚动collectionCell和1个排我看到未来的图像名称“城市”回归,但有必须命名为 “尾子”
我的代码:
的ViewController:
class PhotoStudiosViewController: UIViewController, UITableViewDelegate, UITableViewDataSource, UISearchResultsUpdating {
@IBOutlet weak var tableView: UITableView!
var theStudios: [Studio] = []
var filteredStudios: [Studio] = []
var studiosRef: DatabaseReference!
override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(true)
tableView.estimatedRowHeight = 475
tableView.rowHeight = UITableViewAutomaticDimension
}
override func viewDidLoad() {
super.viewDidLoad()
studiosRef = Database.database().reference(withPath: "PhotoStudios1")
studiosRef.observe(.value, with: { (snapshot) in
for imageSnap in snapshot.children {
let studioObj = Studio(snapshot: imageSnap as! DataSnapshot)
self.theStudios.append(studioObj)
}
self.tableView.reloadData()
})
}
// MARK: - TableView
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if searchController.isActive && searchController.searchBar.text != "" {
return filteredStudios.count
}
return theStudios.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "tableCell", for: indexPath) as! PhotoStudiosTableViewCell
cell.currentPageNumber.text = "1/\(theStudios[indexPath.row].halls.count)"
if searchController.isActive && searchController.searchBar.text != nil {
cell.theHalls = filteredStudios[indexPath.row].halls
} else {
cell.theHalls = theStudios[indexPath.row].halls
}
cell.nameLabel.text = theStudios[indexPath.row].studioName
cell.addressLabel.text = theStudios[indexPath.row].studioAddress
cell.logoLabel.sd_setImage(with: URL(string: theStudios[indexPath.row].studioLogo))
cell.didSelectAction = {
(innerPath) in
self.showDetailsView(indexPath, cellPath: innerPath)
}
return cell
}
TableViewCell:
class PhotoStudiosTableViewCell: UITableViewCell, UICollectionViewDelegate, UICollectionViewDataSource, UIScrollViewDelegate, UICollectionViewDelegateFlowLayout {
@IBOutlet weak var button: UIButton!
@IBOutlet weak var logoLabel: UIImageView!
@IBOutlet weak var nameLabel: UILabel!
@IBOutlet weak var addressLabel: UILabel!
@IBOutlet weak var collectionView: UICollectionView!
@IBOutlet weak var currentPageNumber: UILabel!
var didSelectAction: ((IndexPath) ->())?
var theHalls: [Hall] = [] {
didSet {
collectionView.reloadData()
}
}
var lastContentOffset = CGPoint.zero
override func prepareForReuse() {
super.prepareForReuse()
resetCollectionView()
}
override func awakeFromNib() {
super.awakeFromNib()
currentPageNumber.layer.zPosition = 2
currentPageNumber.layer.cornerRadius = 15.0
currentPageNumber.clipsToBounds = true
}
func resetCollectionView() {
guard !theHalls.isEmpty else { return }
theHalls = []
collectionView.reloadData()
}
// MARK: - CollectionView
func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
return theHalls.count
}
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "collectionCell", for: indexPath) as! PhotoStudiosCollectionViewCell2
cell.hallName.text = theHalls[indexPath.item].hallName
cell.priceLabel.text = theHalls[indexPath.item].hallPrice
cell.metrslabel.text = theHalls[indexPath.item].hallMetrs
cell.photoStudioImage.sd_setImage(with: URL(string: theHalls[indexPath.item].hallImage))
return cell
}
func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
didSelectAction?(indexPath)
}
}
它帮我'cell.collectionView.contentOffset = .zero'。非常感谢,第二天试图解决这个问题。关于其他我会认为我需要它。 – onpro
