I am making an application that allows the user to keep order at usernames and passwords. Currently, I am having a problem when the user quit the app, the data or TableViewCell is not stored or showing up. I am using an array.
I assume because the data is not getting stored after. Is CoreData or UserDefaults a simple solution for this? I want to avoid Firebase.
Can someone explain or show, how to implement CoreData/UserDefaults into the code? I have searched a lot but I simply find it hard to understand how to apply it in my code, especially with arrays and TableViewCell. Help is deeply appreciated.
Pictures are below.
Here is my code:
MainViewController:
class MainViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {
@IBOutlet weak var tableView:UITableView?
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return informasjoner.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "InformasjonTableViewCell") as! InformasjonTableViewCell
let informasjon:Informasjon = informasjoner[indexPath.row];
if(informasjon.image != nil){
cell.imageViewInfo?.image = informasjon.image
} else {
cell.imageViewInfo?.image = UIImage(named: informasjon.imageName!)
}
cell.epostLabel?.text = informasjon.labelEpost
cell.passordLabel?.text = informasjon.labelPassord
cell.applikasjonLabel?.text = informasjon.labelApplikasjon
return cell
}
// EDIT / UPDATE CELL
func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath) -> [UITableViewRowAction]? {
let informasjon = informasjoner[indexPath.row]
let deleteAction = UITableViewRowAction(style: .default, title: "Delete"){
(action, indexPath) in
self.deleteAction(informasjon: informasjon, indexPath: indexPath)
}
//call delete action
deleteAction.backgroundColor = .red;
return [deleteAction]
}
private func deleteAction(informasjon: Informasjon, indexPath: IndexPath){
let alert = UIAlertController(title: "Delete",
message: "Are u sure?",
preferredStyle: .alert)
let deleteAction = UIAlertAction(title: "Yes",
style: .default){ (action) in
informasjoner.remove(at: indexPath.row)
self.tableView?.deleteRows(at: [indexPath], with: .automatic)
}
let cancelAction = UIAlertAction(title: "No",
style: .default,
handler: nil);
alert.addAction(deleteAction);
alert.addAction(cancelAction);
present(alert, animated: true);
}
}
InformasjonTableViewCell:
import UIKit
class InformasjonTableViewCell: UITableViewCell {
@IBOutlet weak var imageViewInfo: UIImageView?
@IBOutlet weak var epostLabel: UILabel?
@IBOutlet weak var passordLabel: UILabel?
@IBOutlet weak var applikasjonLabel: UILabel!
override func awakeFromNib() {
super.awakeFromNib()
// Initialization code
}
override func setSelected(_ selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
}
}
AddInfoVC:
import UIKit
class AddInfoVC: UIViewController, UITextFieldDelegate, UINavigationControllerDelegate, UIImagePickerControllerDelegate {
@IBOutlet weak var txtEpost:UITextField?
@IBOutlet weak var ImageInfo:UIImageView?
@IBOutlet weak var txtPassord:UITextField?
@IBOutlet weak var txtApplikasjon: UITextField!
var newInfo = Informasjon()
@IBAction func btnSave(sender:UIButton){
print("Press Save!")
if(newInfo.image == nil || newInfo.labelEpost?.count == 0 || newInfo.labelPassord?.count == 0 || newInfo.labelApplikasjon?.count == 0){
let alertController = UIAlertController(title: "Alert", message: "Please set", preferredStyle: .alert)
let okAction = UIAlertAction(title: "OK", style: .default){
(action) in
}
alertController.addAction(okAction)
self.present(alertController, animated: true, completion: nil);
} else{
informasjoner.append(newInfo);
navigationController?.popViewController(animated: true)
let mainViewController = self.navigationController?.topViewController as? MainViewController
mainViewController?.tableView?.reloadData()
}
}
override func viewDidLoad() {
super.viewDidLoad()
//Tap to ImageView
let tapGestureToImageView = UITapGestureRecognizer(target: self, action: #selector(tapToImageView(sender:)))
tapGestureToImageView.numberOfTapsRequired = 1
ImageInfo?.isUserInteractionEnabled = true;
ImageInfo?.addGestureRecognizer(tapGestureToImageView);
self.txtEpost?.delegate = self;
self.txtPassord?.delegate = self;
self.txtApplikasjon?.delegate = self;
}
