Pass textfield to a label in a second view controller in swift - ios

Question

I am making a simple client invoice list using a tableView with custom labels in each row. at the top you click the plus sign. This takes you to a second page where you type in your clients name. you hit save and it should add it to the label in the first view controller. I cannot get this to work.
my tableview storyboard has the file called ViewController.swift - in it
import UIKit
var invoiceList = [""]
class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
#IBOutlet var clientTableView: UITableView!
#IBOutlet var clientLabel: UILabel!
public func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int
{
return invoiceList.count
}
public func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell
{
let cell = tableView.dequeueReusableCell(withIdentifier: "clientItem", for: indexPath) as! UITableViewCell
let ClientName = invoiceList[indexPath.row]
cell.textLabel?.text = [clientInput]
return cell
}
func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath) {
if editingStyle == UITableViewCellEditingStyle.delete
{
invoiceList.remove(at: indexPath.row)
clientTableView.reloadData()
}
}
override func viewDidAppear(_ animated: Bool) {
clientTableView.reloadData()
}
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
My second storyboard where you type in the text field. File is called AddInvoiceItem.swift. in it -
import UIKit
class AddInvoiceViewController: UIViewController {
var clientTextField:String!
#IBOutlet var clientInput: UITextField!
#IBAction func addItem(_ sender: Any) {
if clientInput.text != ""
{
invoiceList.append(clientInput.text!)
clientInput.text = ""
_ = navigationController?.popViewController(animated: true)
}
}
#IBAction func cancelBtn(_ sender: Any) {
_ = navigationController?.popViewController(animated: true)
}
}
My error keeps happening when I am trying to use the code line
public func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell
{
let cell = tableView.dequeueReusableCell(withIdentifier: "clientItem", for: indexPath) as! UITableViewCell
let ClientName = invoiceList[indexPath.row]
cell.textLabel?.text = [clientInput]
return cell
}
The cell.textLabel?.text = [clientInput]
I know this is wrong, but cannot figure it out!

Answer 1

Make a new cell class
class CustomCell: UITableViewCell {
//Make your outlets here, connect the outlets from cell in your storyboard like ClientNameLabel
}
Please select the cell on your Storyboard, and enter the name of your class in this field. In your case it would be CustomCell
then in ViewController
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell
{
let cell = tableView.dequeueReusableCell(withIdentifier: "clientItem", for: indexPath) as! CustomCell
let ClientName = invoiceList[indexPath.row]
cell.ClientNameLabel.text = ClientName
return cell
}
