Segue way from custom UITableViewCell to a popup View with data - ios

Question

I have a create a xib as customTableViewCell and on my main storyboard, I have a ViewController as a popUp and have link the viewController to the popUp through a segue way. Now I am trying to open the popUp through didSelectRowAt. When I run the app and click on a row it gives error
<CustomTableCell.ViewController: 0x7feb4650ea00>) has no segue with identifier 'popUp'
Below is my code
import UIKit
import os.log
class ViewController: UITableViewController {
var data = [Response.Recipe]()
override func viewDidLoad() {
super.viewDidLoad()
navigationItem.title = "Restaurants"
downloadJson()
tableView.delegate = self
tableView.dataSource = self
//tableView.register(UITableViewCell.classForCoder(), forCellReuseIdentifier: "Cell")
let nib = UINib(nibName: "viewTblCell", bundle: nil)
tableView.register(nib, forCellReuseIdentifier: "customCell")
if #available(iOS 10.0, *) {
tableView.refreshControl = refresher
} else {
tableView.addSubview(refresher)
}
// sampleData()
}
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return data.count
}
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
guard let cell: CustomTableViewCell = self.tableView.dequeueReusableCell(withIdentifier: "customCell", for: indexPath) as? CustomTableViewCell else {
os_log("Dequeue cell isn't an instance of CustomTableCell", log: .default, type: .debug)
fatalError()
}
cell.recipeNameLbl?.text = data[indexPath.row].recipeName
let image = data[indexPath.row].recipeImage
let ImageUrl = "http://localhost:8888/restaurant/recipeImages/"+image
if let imageURL = URL(string: ImageUrl) {
DispatchQueue.global().async {
let data = try? Data(contentsOf: imageURL)
if let data = data {
let image = UIImage(data: data)
DispatchQueue.main.async {
cell.recipeImg?.image = image
}
}
}
}
let restaurantOpen = data[indexPath.row].restaurantStatus
if restaurantOpen == "Closed" {
cell.restaurantStatusLbl?.text = restaurantOpen
cell.restaurantStatusLbl?.isHidden = false
}else{
cell.restaurantStatusLbl?.isHidden = true
}
cell.restaurantOperateDays?.text = data[indexPath.row].restaurantOpenDays
cell.restaurantOperateTime?.text = data[indexPath.row].restaurantOpenTime
cell.retaurantNameLbl?.text = data[indexPath.row].restaurantName
cell.recipeTimeLbl?.text = "Delivers in " + String(describing: data[indexPath.row].recipeTime) + " minutes"
cell.recipePriceLbl?.text = "GHS " + String(describing: data[indexPath.row].recipePrice)
//cell.delegate = self
return cell
}
override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
performSegue(withIdentifier: "popUp", sender: self)
print(data[indexPath.row].recipeName)
}
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if let destination = segue.destination as? AddToCartViewController {
destination.popUpDetails = data[(tableView.indexPathForSelectedRow?.row)!]
}
}
override func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return 230
}
func downloadJson() {
let url = URL(string: "http://localhost:8888/restaurant/tableView.php")
guard let downloadURL = url else { return }
URLSession.shared.dataTask(with: downloadURL) { data, urlResponse, error in
guard let data = data, error == nil, urlResponse != nil else {
print("something is wrong")
return
}
print("downloaded")
do
{
let decoder = JSONDecoder()
let downloadedRecipes = try decoder.decode(Response.self, from: data)
self.data = downloadedRecipes.recipeTbl
print(downloadedRecipes.recipeTbl)
DispatchQueue.main.async {
self.tableView.reloadData()
}
} catch {
print(error)
}
}.resume()
}
lazy var refresher: UIRefreshControl = {
let refreshControl = UIRefreshControl()
refreshControl.tintColor = UIColor.red
refreshControl.addTarget(self, action: #selector(requestData), for: .valueChanged)
return refreshControl
}()
#objc func requestData(){
let deadline = DispatchTime.now() + .milliseconds(800)
DispatchQueue.main.asyncAfter(deadline: deadline){
self.downloadJson()
self.refresher.endRefreshing()
}
}
}

I finally achieved what I wanted to do
I move the popUp to its own storyboard then gave it Storyboard ID "addToCart"
Then I open it in the didSelectRowat method
override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
let popup = UIStoryboard(name: "AddToCart", bundle: nil)
let addToCartPopup = popup.instantiateInitialViewController()! as! AddToCartViewController
addToCartPopup.popUpDetails = data[(tableView.indexPathForSelectedRow?.row)!]
self.present(addToCartPopup, animated: true)
}
