Hello good afternoon to everyone. I hope you are doing very well despite the situation we are going through. I tell you my problem. I am trying to save in an array, a series of data that is selected from a tableView through a JSON. That is, the tableView shows some data available to select, the ones that are selected I want to save them in an array but when I select a data in the tableView my app crashes and shows me a breakpoint "Thread 1: signal SIGABRT" And in the console I get this: Could not cast value of type 'MallConcierge.DetallesIntereses' (0x10ca9be10) to 'NSString' (0x7fff86d8bbb0). I hope you can help me, I attach the classes from where I download the data, the details and the class where I connect the tableView.
InteresesModelo.swift (in this class is where I download the data in JSON)
import UIKit
protocol InteresesModeloProtocol: class{
func interesesDownload (interest: NSArray)
}
class InteresesModelo: NSObject {
weak var delegate: InteresesModeloProtocol!
let urlPath = "http://localhost:8888/mallconcierge/API-movil/interests.php"
func interestDownload(){
let url: URL = URL(string: urlPath)!
let defaultSession = Foundation.URLSession(configuration: URLSessionConfiguration.ephemeral)
URLCache.shared.removeAllCachedResponses()
let task = defaultSession.dataTask(with: url){
(data, response, error) in
if error != nil{
print("Error al descargar datos")
}else{
print("Datos descargados")
self.parseJSON(data!)
}
}
task.resume()
}
func parseJSON(_ data:Data){
var jsonResult = NSArray()
do{
jsonResult = try JSONSerialization.jsonObject(with: data, options: JSONSerialization.ReadingOptions.allowFragments) as! NSArray
}catch let error as NSError{
print(error)
}
var jsonElement = NSDictionary()
let detalles = NSMutableArray()
for i in 0 ..< jsonResult.count{
jsonElement = jsonResult[i] as! NSDictionary
let detalle = DetallesIntereses()
let idInteres = jsonElement["idInteres"]
let nombreInteres = jsonElement["interesNombre"]
detalle.idInteres = idInteres as? String
detalle.nombreInteres = nombreInteres as? String
detalles.add(detalle)
}
DispatchQueue.main.async(execute: { ()-> Void in
self.delegate.interesesDownload(interest: detalles)
})
}
}
DetallesIntereses.swift
import UIKit
class DetallesIntereses: NSObject {
var idInteres: String?
var nombreInteres: String?
override init() {
}
init(idInteres: String, nombreInteres:String) {
self.idInteres = idInteres
self.nombreInteres = nombreInteres
}
override var description: String{
return "idInteres: \(idInteres), nombreInteres: \(nombreInteres)"
}
}
InteresesViewController.swift
import UIKit
class InteresesViewController: UIViewController, UITableViewDelegate, UITableViewDataSource, InteresesModeloProtocol {
var selectIntereses = [String]()
var feedInterests: NSArray = NSArray()
// var selectInterests: DetallesIntereses = DetallesIntereses()
var items=[String]()
@IBOutlet var listaInteresesTableView: UITableView!
func interesesDownload(interest: NSArray) {
feedInterests = interest
self.listaInteresesTableView.reloadData()
}
override func viewDidLoad() {
self.listaInteresesTableView.isEditing = true
self.listaInteresesTableView.allowsMultipleSelectionDuringEditing = true
self.listaInteresesTableView.delegate = self
self.listaInteresesTableView.dataSource = self
let interesesModelo = InteresesModelo()
interesesModelo.delegate = self
interesesModelo.interestDownload()
super.viewDidLoad()
// Do any additional setup after loading the view.
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return feedInterests.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "celInterests", for: indexPath) as! InteresesTableViewCell
let interest: DetallesIntereses = feedInterests[indexPath.row] as! DetallesIntereses
cell.lblNombreIntereses!.text = interest.nombreInteres
return cell
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
self.selectDeselectCell(tableView: listaInteresesTableView, indexPath: indexPath)
print("Seleccionado")
}
func tableView(_ tableView: UITableView, didDeselectRowAt indexPath: IndexPath) {
self.selectDeselectCell(tableView: listaInteresesTableView, indexPath: indexPath)
print("Deseleccionado")
}
func selectDeselectCell(tableView: UITableView, indexPath: IndexPath){
self.selectIntereses.removeAll()
if let arr = listaInteresesTableView.indexPathsForSelectedRows{
for index in arr{
selectIntereses.append(feedInterests[indexPath.row] as! String)
}
}
print(selectIntereses)
}
@IBAction func seleccionarIntereses(_ sender: Any){
print(selectIntereses)
}
/*

}
The JSON

I hope you can help me, please. I thank you all
