Value in JSON does not display in tableviewcell custom - ios

Question

Can't display data in TableViewCell.Data reports of events, but the when you open the array "sports" display the data in cels no.The display of the title occurs and the transfer is ended...
This is my json code...
Event.swift
import UIKit
struct Event {
let match : String
let forecast : String
let data : String
let image : UIImage
var sports : [Sport]
init (match : String, forecast : String, data: String, image : UIImage, sports : [Sport]) {
self.match = match
self.forecast = forecast
self.data = data
self.image = image
self.sports = sports
}
static func eventsFromBundle ()-> [Event] {
var events = [Event] ()
guard let url = Bundle.main.url(forResource: "events", withExtension: "json") else {
return events
}
do {
let data = try Data(contentsOf: url)
guard let rootObject = try JSONSerialization.jsonObject(with: data, options: .allowFragments) as? [String : Any] else {
return events
}
guard let eventObjects = rootObject["events"] as? [[String: AnyObject]] else {
return events
}
for eventObject in eventObjects {
if let match = eventObject["match"] as? String,
let forecast = eventObject["forecast"] as? String,
let data = eventObject["data"] as? String,
let imageName = eventObject["image"] as? String,
let image = UIImage(named: imageName),
let sportsObject = eventObject["sports"] as? [[String : String]]{
var sports = [Sport]()
for sportObject in sportsObject {
if let nameTitle = sportObject["name"] ,
let titleName = sportObject["image"],
let titleImage = UIImage(named: titleName + ".jpg"),
let prognozLabel = sportObject["prognoz"],
let obzor = sportObject["obzor"] {
sports.append(Sport(name: nameTitle, prognoz: prognozLabel, image: titleImage, obzor: obzor, isExpanded: false))
}
}
let event = Event(match: match, forecast: forecast, data: data, image: image, sports: sports)
events.append(event)
}
}
} catch {
return events
}
return events
}
}
import UIKit
class SportViewController: BaseViewController {
var events = Event.eventsFromBundle ()
#IBOutlet weak var tableView: UITableView!
override func viewDidLoad() {
super.viewDidLoad()
addSlideMenuButton()
tableView.rowHeight = UITableViewAutomaticDimension
tableView.estimatedRowHeight = 100
}
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
NotificationCenter.default.addObserver(forName: .UIContentSizeCategoryDidChange, object: .none, queue: OperationQueue.main) { [weak self] _ in
self?.tableView.reloadData()
}
}
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if let destination = segue.destination as? SportDetailViewController,
let indexPath = tableView.indexPathForSelectedRow {
destination.selectedEvent = events[indexPath.row]
}
}
}
extension SportViewController: UITableViewDataSource {
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return events.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cellMatch", for: indexPath) as! SportTableViewCell
let event = events[indexPath.row]
cell.matchLabel.text = event.match
cell.imageMatch.image = event.image
cell.forecastLabel.text = event.forecast
cell.dataLabel.text = event.data
cell.matchLabel.font = UIFont.preferredFont(forTextStyle: .subheadline)
cell.forecastLabel.font = UIFont.preferredFont(forTextStyle: .callout)
return cell
}
}
Her is the controller.SportDetailViewController.swift
import UIKit
class SportDetailViewController: UIViewController {
var selectedEvent : Event!
let obzorText = "Select for more info >"
#IBOutlet weak var tableView: UITableView!
override func viewDidLoad() {
super.viewDidLoad()
title = selectedEvent.match
tableView.rowHeight = UITableViewAutomaticDimension
tableView.estimatedRowHeight = 300
// Do any additional setup after loading the view.
}
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
}
}
extension SportDetailViewController: UITableViewDataSource {
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int
{
return selectedEvent.sports.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell : SportDetailTableViewCell = tableView.dequeueReusableCell(withIdentifier: "cellMatch", for: indexPath) as! SportDetailTableViewCell
let sport = selectedEvent.sports[indexPath.row]
cell.nameTitle.text = sport.name
cell.titleImage.image = sport.image
cell.prognozLabel.text = sport.prognoz
cell.selectionStyle = .none
cell.nameTitle.backgroundColor = UIColor.darkGray
cell.backgroundColor = UIColor.red
cell.obzorText.text = sport.isExpanded ? sport.obzor : obzorText
cell.obzorText.textAlignment = sport.isExpanded ? .left : .center
return cell
}
}
extension SportDetailViewController: UITableViewDelegate {
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
guard let cell = tableView.cellForRow(at: indexPath) as? SportDetailTableViewCell else { return }
var sport = selectedEvent.sports[indexPath.row]
sport.isExpanded = !sport.isExpanded
selectedEvent.sports[indexPath.row] = sport
cell.obzorText.text = sport.isExpanded ? sport.obzor : obzorText
cell.obzorText.textAlignment = sport.isExpanded ? .left : .center
tableView.beginUpdates()
tableView.endUpdates()
tableView.scrollToRow(at: indexPath, at: .top, animated: true)
}
}
all these methods have tried: tableview.datasource = self , tableview.delegate = self и reloadData().....in viewDidLoad.

Answer 1

Delete this init from your struct: (because struct gets free initializer)
init (match : String, forecast : String, data: String, image : UIImage, sports : [Sport]) {
self.match = match
self.forecast = forecast
self.data = data
self.image = image
self.sports = sports
}
Now, your var events won't be populated as you are calling method in class scope. So change this:
class SportViewController: BaseViewController {
var events = Event.eventsFromBundle ()
...
...
}
to
class SportViewController: BaseViewController {
var events = [Event]()
...
...
override func viewDidLoad() {
super.viewDidLoad()
addSlideMenuButton()
tableView.rowHeight = UITableViewAutomaticDimension
tableView.estimatedRowHeight = 100
events = Event().eventsFromBundle()
}
...
...
}
This should solve your problem.
