Ho trovato una soluzione ma c'è ancora qualcosa che non va... il timer non parte, perché?
import UIKit
import Foundation
class Testios: UIViewController, UITableViewDataSource, UITableViewDelegate {
@IBOutlet weak var Tabella: UITableView!
var lista: [String] = []
var a: String?
var b: String?
let currentDate = Date()
let dateFormatter = DateFormatter()
let userCalendar = Calendar.current
let requestedComponent: Set<Calendar.Component> = [.day,.hour,.minute,.second,.month,.year]
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return lista.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "Testios", for: indexPath)
cell.textLabel?.text = lista[indexPath.row]
return cell
}
override func viewDidLoad() {
super.viewDidLoad()
let timer = Timer.scheduledTimer(timeInterval: 1.0, target: self, selector: #selector(printTime), userInfo: nil, repeats: true)
timer.fire()
}
func printTime()
{
dateFormatter.dateFormat = "yyyy/MM/dd hh:mm:ss"
let startTime = Date()
let endTime = dateFormatter.date(from: "2018/02/01 00:00:00")
let timeDifference = userCalendar.dateComponents(requestedComponent, from: startTime, to: endTime!)
let dateLabelOutlet = "\(timeDifference.year!) Years \(timeDifference.month!) Months \(timeDifference.day!) Days \(timeDifference.hour!) Hours \(timeDifference.day!) Days \(timeDifference.hour!) Hours \(timeDifference.minute!) Minutes \(timeDifference.second!) Seconds"
lista.append(dateLabelOutlet)
}
}
