How do I parse json with more then one values? - ios

Question

I'm trying to parse a JSON file to my code.
So, far I have managed to do so except for one key (genre) that has an array of values.
I want to know how can I parse it so I can present it in a UILabel?
JSON data in file:
[{
"title": "Dawn of the Planet of the Apes",

Movie class:

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 Class:
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
}
}

Swift 3.0
Just analyse below code and apply it to your issue
The Movie class becomes,
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
}
}
}
Class that had UITableView
The global variable of the class is,
var movieData = Array<Movie>()
The JSON parse will becomes,
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
}
OUTPUT:-
