你好，我正在开发一个用于检索有关电影的数据的应用程序，但我有一个问题，我正在使用 CollectionView 来显示电影类别和这些类别内部(在集合视图单元格内(我正在使用另一个集合视图根据电影类别显示电影，但我无法填充第二个集合视图的单元格，因为它是自定义单元格的子类，我还创建了一个 xib文件，我正在尝试为我为自定义单元格制作的类中的第二个集合视图实现委托和数据源方法，这是我代码的一部分：
func parseJson(category:MovieCategory)
{
let currentCategory = category
let parameters = ["api_key":"8460d476d21be7e26a99234d8ca8de51","sort_by":"false","include_video":"false","with_genres":currentCategory.genreID]
Alamofire.request(AppModel().url, method: .get, parameters: parameters).responseJSON { (response) in
if response.result.isSuccess{
let movieJSON = JSON(response.result.value!)
for i in 0..<20{
let title = movieJSON["results"][i]["title"].stringValue
let posterPath = movieJSON["results"][i]["poster_path"].stringValue
let overview = movieJSON["results"][i]["overview"].stringValue
let dateReleased = movieJSON["results"][i]["release_date"].stringValue
let voteAverage = movieJSON["results"][i]["vote_average"].stringValue
print(title)
if let safeImage = AppModel().createImage(posterPath: posterPath)
{
let movieDetails = MovieDetails(movieTitle: title, poster: safeImage, voteAverage: voteAverage, overview: overview, releaseDate: dateReleased)
currentCategory.categoryMovies.append(movieDetails)
}
}
}
}
}
以及我想使用从 API 检索到的数据的位置：
class CategoryCollectionViewCell:UICollectionViewCell,UICollectionViewDelegate,UICollectionViewDataSource{
@IBOutlet weak var sectionName: UILabel!
@IBOutlet weak var movieCollectionView: UICollectionView!
var sectionNumber:Int = 0
let appModel = AppModel()
override func awakeFromNib() {
super.awakeFromNib()
movieCollectionView.delegate = self
movieCollectionView.dataSource = self
movieCollectionView.register(UINib(nibName: "CollectionViewCell", bundle: nil), forCellWithReuseIdentifier: "cell")
}
@IBAction func viewAllPressed(_ sender: UIButton) {
}
func numberOfSections(in collectionView: UICollectionView) -> Int {
appModel.movieCategories.count
}
func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
return appModel.movieCategories[section].categoryMovies.count
}
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = movieCollectionView.dequeueReusableCell(withReuseIdentifier: "categoryCell", for: indexPath) as! CollectionViewCell
cell.posterImage.image = appModel.movieCategories[indexPath.section].categoryMovies[indexPath.item].poster
return cell
}
} 这些是模型类：
class MovieDetails{
let movieTitle:String
let poster:UIImage
let voteAverage:String
let overview:String
let releaseDate:String
init(movieTitle:String,poster:UIImage,voteAverage:String,overview:String,releaseDate:String) {
self.movieTitle = movieTitle
self.overview = overview
self.poster = poster
self.releaseDate = releaseDate
self.voteAverage = voteAverage
}
}
class MovieCategory {
var genreID:String = ""
var categoryTitle:String = ""
var categoryMovies:[MovieDetails] = []
init(genreID:String,categoryTitle:String) {
self.genreID = genreID
self.categoryTitle = categoryTitle
}
}
我认为我的问题是我不知道在 CategoryCollectionViewCell 中在哪里调用 parseJson 以及在哪里调用 reloadData((。 如果你对此有任何了解，请帮助我 谢谢。
认为它的工作： 写在你的Alamofire Func和之后(.success(和(.failure(
self.yourCollectionView.reloadData((
