UITableView: Load data from array after viewDidLoad() - ios

Question

I'm trying to load the items of an array into a UITableView in a Swift iOS App.
ViewController.swift
import UIKit
class ViewController: UIViewController {
let website = MyWebsite()
let authenticated = ViewAuthenticated()
override func viewDidLoad() {
super.viewDidLoad()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
#IBAction func getData(_ sender: Any) {
var arrayTEST = self.website.getArray() //["red", "green", "blue"]
self.authenticated.data = arrayTEST //["red", "green", "blue"]
let viewAuth = self.storyboard?.instantiateViewController(withIdentifier: "ViewAuthenticated") as! ViewAuthenticated
self.present(viewAuth, animated: true)
}
}
ViewAuthenticated.swift
import UIKit
class ViewAuthenticated: UIViewController, UITableViewDataSource {
#IBOutlet weak var tableView: UITableView!
override func viewDidLoad() {
super.viewDidLoad()
tableView.dataSource = self
}
func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
public var data: [String] = ["123", "456", "789"]
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return data.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cellReuseIdentifier")!
let text = data[indexPath.row]
cell.textLabel?.text = text
return cell
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
}
What I would like to do is creating a UITableView containing the items sent by ViewController.
I think the problem is that in ViewAuthenticated the UITableView is created before ViewController sends his new array (["red", "green", "blue"]).
How can I solve this?

Answer 1

You should set the array of values to data property of ViewAuthenticated View, before presenting the view.
#IBAction func getData(_ sender: Any) {
var arrayTEST = self.website.getArray() //["red", "green", "blue"]
self.authenticated.data = arrayTEST //["red", "green", "blue"]
let viewAuth = self.storyboard?.instantiateViewController(withIdentifier: "ViewAuthenticated") as! ViewAuthenticated
viewAuth.data = self.authenticated.data
self.present(viewAuth, animated: true)
}
And remove the hardcoded data array value. Change it to :
var data: [String] = []

Answer 2

Simple solution, the authenticated controller is not needed at all:
let authenticated = ViewAuthenticated()
...
#IBAction func getData(_ sender: Any) {
let viewAuth = self.storyboard?.instantiateViewController(withIdentifier: "ViewAuthenticated") as! ViewAuthenticated
viewAuth.data = self.website.getArray() //["red", "green", "blue"]
self.present(viewAuth, animated: true)
}
