我怎样才能parsing每个项目到它的uicollection视图单元格
所以下面是我的parsingJSON并将其放入一个集合视图单元格的代码
import UIKit let cellId = "cellId" struct AnimeJsonStuff: Decodable { let data: [AnimeDataArray] } struct AnimeLinks: Codable { var selfStr : String? private enum CodingKeys : String, CodingKey { case selfStr = "self" } } struct AnimeAttributes: Codable { var createdAt : String? var slug : String? let synopsis: String? private enum CodingKeys : String, CodingKey { case createdAt = "createdAt" case slug = "slug" case synopsis = "synopsis" } } struct AnimeRelationships: Codable { var links : AnimeRelationshipsLinks? private enum CodingKeys : String, CodingKey { case links = "links" } } struct AnimeRelationshipsLinks: Codable { var selfStr : String? var related : String? private enum CodingKeys : String, CodingKey { case selfStr = "self" case related = "related" } } struct AnimeDataArray: Codable { let id: String? let type: String? let links: AnimeLinks? let attributes: AnimeAttributes? let relationships: [String: AnimeRelationships]? private enum CodingKeys: String, CodingKey { case id = "id" case type = "type" case links = "links" case attributes = "attributes" case relationships = "relationships" } } class OsuHomeController: UICollectionViewController, UICollectionViewDelegateFlowLayout { override func viewDidLoad() { super.viewDidLoad() // Do any additional setup after loading the view, typically from a nib. navigationItem.title = "Kitsu - Your anime feed" collectionView?.backgroundColor = UIColor(red:0.09, green:0.13, blue:0.19, alpha:1.0) collectionView?.register(viewControllerCells.self, forCellWithReuseIdentifier: cellId) } override func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int { return 3 } override func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell { return collectionView.dequeueReusableCell(withReuseIdentifier: cellId, for: indexPath) } func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize { return CGSize(width: 350, height: 150) } func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, insetForSectionAt section: Int) -> UIEdgeInsets { return UIEdgeInsets(top: 15, left: 0, bottom: 10, right: 0) } override func didReceiveMemoryWarning() { super.didReceiveMemoryWarning() // Dispose of any resources that can be recreated. } } class viewControllerCells: UICollectionViewCell { func jsonDecoding() { let jsonUrlString = "https://kitsu.io/api/edge/anime" guard let url = URL(string: jsonUrlString) else {return} URLSession.shared.dataTask(with: url) { (data, response, err) in guard let data = data else {return} do { let animeJsonStuff = try JSONDecoder().decode(AnimeJsonStuff.self, from: data) for anime in animeJsonStuff.data { // print(anime.id) // print(anime.type) // print(anime.links?.selfStr) let animeName = anime.attributes?.slug let animeSynopsis = anime.attributes?.synopsis print(animeName) DispatchQueue.main.async { self.nameLabel.text = animeName self.synopsis.text = animeSynopsis } for (key, value) in anime.relationships! { // print(key) // print(value.links?.selfStr) // print(value.links?.related) } } } catch let jsonErr { print("Error serializing json", jsonErr) } }.resume() } let nameLabel: UILabel = { let label = UILabel() label.textColor = UIColor.black return label }() let profileImageView: UIImageView = { let imageView = UIImageView() imageView.contentMode = .scaleAspectFit return imageView }() let synopsis: UILabel = { let label = UILabel() label.textColor = UIColor.black return label }() override init(frame: CGRect) { super.init(frame: frame) setupViews() jsonDecoding() self.layer.shadowOpacity = 0.05 self.layer.shadowRadius = 0.05 self.layer.cornerRadius = 1 } required init?(coder aDecoder: NSCoder) { fatalError("init(coder:) has not been implemented") } func setupViews() { backgroundColor = UIColor(red:0.86, green:0.87, blue:0.89, alpha:1.0) addSubview(nameLabel.self) addSubview(synopsis.self) addConstraintsWithFormat("H:|-18-[v0]|", views: synopsis) addConstraintsWithFormat("V:|-8-[v0]|", views: synopsis) addConstraintsWithFormat("H:|-12-[v0]|", views: nameLabel) } } extension UIColor { static func rgb(_ red: CGFloat, green: CGFloat, blue: CGFloat) -> UIColor { return UIColor(red: red/255, green: green/255, blue: blue/255, alpha: 1) } } extension UIView { func addConstraintsWithFormat(_ format: String, views: UIView...) { var viewsDictionary = [String: UIView]() for (index, view) in views.enumerated() { let key = "v\(index)" viewsDictionary[key] = view view.translatesAutoresizingMaskIntoConstraints = false } addConstraints(NSLayoutConstraint.constraints(withVisualFormat: format, options: NSLayoutFormatOptions(), metrics: nil, views: viewsDictionary)) } 哪些工作，但是，而不是像这样的所有数据
Optional("cowboy-bebop") Optional("cowboy-bebop-tengoku-no-tobira") Optional("trigun") Optional("witch-hunter-robin") Optional("beet-the-vandel-buster") Optional("eyeshield-21") Optional("honey-and-clover") Optional("hungry-heart-wild-striker") Optional("initial-d-fourth-stage") Optional("monster") Optional("cowboy-bebop") Optional("cowboy-bebop-tengoku-no-tobira") Optional("trigun") Optional("witch-hunter-robin") Optional("beet-the-vandel-buster") Optional("eyeshield-21") Optional("honey-and-clover") Optional("hungry-heart-wild-striker") Optional("initial-d-fourth-stage") Optional("monster") Optional("cowboy-bebop") Optional("cowboy-bebop-tengoku-no-tobira") Optional("trigun") Optional("witch-hunter-robin") Optional("beet-the-vandel-buster") Optional("eyeshield-21") Optional("honey-and-clover") Optional("hungry-heart-wild-striker") Optional("initial-d-fourth-stage") Optional("monster")
它是这样的 ，这是错误的，它应该显示从上到下的每个节目，而不仅仅是最后一个。 我曾经问过这个问题，他们说，把它放在主视图负载然后返回索引path的项目单元格，我会猜测anime.attrubites.slug似乎并没有工作。
请检查 ：
