I have a UITableView where data is loaded from a database, a JSON. How do I get this when I select a line, which is taken in another view?
The automarke is to be selected in the tableview and displayed in the label of the other view.
class AutoMarkeTableView: UITableViewController {
var items = [[String:AnyObject]]()
@IBOutlet var myTableView: UITableView!
override func viewDidLoad() {
super.viewDidLoad()
let url = URL(string: "URL_LINK")!
let urlSession = URLSession.shared
let task = urlSession.dataTask(with: url) { (data, response, error) in
// JSON parsen und Ergebnis in eine Liste von assoziativen Arrays wandeln
let jsonData = try! JSONSerialization.jsonObject(with: data!, options: [])
self.items = jsonData as! [[String:AnyObject]]
// UI-Darstellung aktualisieren
OperationQueue.main.addOperation {
self.tableView.reloadData()
}
}
task.resume()
}
override func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return items.count
}
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "markeCell", for: indexPath)
let item = items[indexPath.row]
cell.textLabel?.text = item["makename"] as? String
return cell
}
}
class FahrzeugAngabenView: UIViewController {
@IBOutlet weak var itemMarkeLabel: UILabel!
}
You could temporarily save the selected item in a variable. Something like this:
var selectedItem: Item?
func tableView(tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
selectedItem = items[indexPath.row]
self.performSegue(withIdentifier: "auto", sender: self)
}
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if segue.identifier == "auto" {
let destVc = segue.destination as! FahrzeugAngabenView
destVc.selectedItemName = selectedItem.title
selectedItem = nil
}
}
Not the most elegant solution, but i would expect this to work.
