Blank labels after data passing in Swift 4?
-1
I am currently trying to pass data from my table view controller to a second view controller but my labels and image are appearing as blank in the second view controller.
This is my main event view controller:
class EventsTableViewController: PFQueryTableViewController {
override func queryForTable() -> PFQuery<PFObject> {
let query = PFQuery(className: "Events")
//query.order(byAscending: "location")
query.order(byAscending: "date")
return query
}
override func viewDidLoad() {
super.viewDidLoad()
self.title = "Upcoming Events"
// Do any additional setup after loading the view.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if segue.identifier == "MasterToDetail" {
let detailVC = segue.destination as! DetailViewController
detailVC.myEventCell = sender as? EventCell
}
}
}
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath, object: PFObject?) -> PFTableViewCell? {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! EventCell
cell.dateLabel.text = object?.object(forKey: "date") as? String
cell.locationLabel.text = object?.object(forKey: "location") as? String
cell.nameLabel.text = object?.object(forKey: "name") as? String
let imageFile = object?.object(forKey: "image") as? PFFile
cell.eventImage.image = UIImage(named: "download")
cell.eventImage.file = imageFile
cell.eventImage.loadInBackground()
return cell
}
override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
performSegue(withIdentifier: "MasterToDetail", sender: EventCell())
}
@IBAction func reloadTable(_ sender: Any) {
self.loadObjects()
}
@IBAction func onSignOutTapped(_ sender: Any) {
let firebaseAuth = Auth.auth()
do {
try firebaseAuth.signOut()
performSegue(withIdentifier: "signOutSegue", sender: nil)
} catch {
print (error)
}
}
}
and my second view controller:
class DetailViewController: UIViewController {
@IBOutlet weak var detailImageView: UIImageView!
@IBOutlet weak var detailNameLabel: UILabel!
@IBOutlet weak var detailDescriptionLabel: UILabel!
@IBOutlet weak var detailLocationLabel: UILabel!
var myEventCell: EventCell?
override func viewDidLoad() {
super.viewDidLoad()
setUI()
}
func setUI () {
detailNameLabel.text = myEventCell?.nameLabel.text
detailImageView.image = myEventCell?.eventImage.image
detailLocationLabel.text = myEventCell?.locationLabel.text
}
}
swift

As you send an empty cell here
performSegue(withIdentifier: "MasterToDetail", sender: EventCell())
You need
let cell = tableView.cellForRow(at:indexPath)
performSegue(withIdentifier: "MasterToDetail", sender:cell)
