【中文标题】如何解析具有多个值的 json？【英文标题】：How do I parse json with more then one values? 【发布时间】：2017-07-01 12:12:07 【问题描述】：我正在尝试将 JSON 文件解析为我的代码。
所以，到目前为止，我已经设法做到了，除了一个具有一组值的键（流派）。
我想知道如何解析它，以便可以在UILabel 中呈现它？
文件中的 JSON 数据：

Movie类：
import UIKit
class Movie
var title = ""
var image = ""
var rating = 0.0
var releaseYear = 0
init(object: [String: AnyObject])
self.title = object["title"] as! String
self.image = object["image"] as! String
self.rating = object["rating"] as! Double
self.releaseYear = object["releaseYear"] as! Int
init()
MovieCell班级：
import UIKit
import SDWebImage
class MovieCell: UITableViewCell
@IBOutlet weak var titleLbl: UILabel!
@IBOutlet weak var releaseYearLbl: UILabel!
@IBOutlet weak var ratingLbl: UILabel!
@IBOutlet weak var movieImage: UIImageView!
@IBOutlet weak var genreLbl: UILabel!
override func awakeFromNib()
super.awakeFromNib()
func createCell(movie: Movie)
self.titleLbl.text = movie.title
self.releaseYearLbl.text = "\(movie.releaseYear)"
self.ratingLbl.text = "\(movie.rating) ⭐️"
movieImage.layer.cornerRadius = 10.0
movieImage.clipsToBounds = true
self.movieImage.sd_setImage(with: URL(string: movie.image))
override func setSelected(_ selected: Bool, animated: Bool)
super.setSelected(selected, animated: animated)
// Configure the view for the selected state

【参考方案1】：Swift 3.0
只需分析以下代码并将其应用于您的问题
Movie 类变为，
class Movie
var title = ""
var image = ""
var rating = 0.0
var releaseYear = 0
var genre:String?
init(object: [String: AnyObject])
self.title = object["title"] as! String
self.image = object["image"] as! String
self.rating = object["rating"] as! Double
self.releaseYear = object["releaseYear"] as! Int
let genreArray = object["genre"] as! [String]
/*Whatever you want do here with genre. I thought you need whole array to one readable String*/
for strings in genreArray
self.genre = self.genre == nil ? strings : self.genre!+" "+strings
有UITableView的类
类的全局变量是，
var movieData = Array<Movie>()
JSON 解析会变成，
if let json = try! JSONSerialization.jsonObject(with: data, options: .allowFragments) as? Array<Dictionary<String, AnyObject>>
for object in json
self.movieData.append(Movie(object: object))
DispatchQueue.main.async
self.tableView.reloadData()
UITableView datasource
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int
return movieData.count
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell
let cell = self.tableView.dequeueReusableCell(withIdentifier: "cell", for:indexPath)
let tableObject:Movie = self.movieData[indexPath.row]
cell.textLabel?.text = tableObject.genre //This way you will be get all values and apply it to whatever you want...
return cell
输出：-
