I have a ViewController(VCA) with a TableView inside. From this ViewController it is possibile to call another ViewController (VCB). In this second VC it is possibile add an item to the plist used to populate the TableView in VCA. The problem is that when I save the new item and dismiss the VCB, I can't reload the TableView in VCA.
I have found a lot of examples:
How can you reload a ViewController after dismissing a modally presented view controller in Swift?
How to call reload table view after you call dismissViewController in swift?
How to reload tableview from another view controller in swift
Update the data of a TableViewController after add item
Update the first view after dismissing Popover
Table view is not getting updated after dismissing the popover?
after reading i tried with this code:
**IN VCB**
import UIKit
protocol AddItemDelegateProtocol {
func didAddItem()
}
class VCB: UIViewController {
var delegate : AddItemDelegateProtocol?
...
}
@IBAction func saveButton(_ sender: Any) {
....
self.delegate?.didAddItem()
dismiss(animated: true, completion: nil)
}
**In VCA**
class VCA: UIViewController, UITableViewDelegate, UITableViewDataSource, AddItemDelegateProtocol {
let addItemVC = VCB()
...
override func viewDidLoad() {
super.viewDidLoad()
addItemVC.delegate = self
...
}
func didAddItem() {
self.tableView.reloadData()
}
but this doesn't work. I don't understand where I'm wrong. Could you help me?
EDIT: my Solution I solved in this way:
I've created a singleton in which I declare:
class DataManager {
static let shared = DataManager()
var firstVC = VCA()
.....
}
then, in viewDidLoad of VCA:
DataManager.shared.firstVC = self
now, in the saveButton of VCB, i can call:
@IBAction func saveButton(_ sender: Any) {
........
DataManager.shared.firstVC.tableView.reloadData()
dismiss(animated: true, completion: nil)
}
