How to make UITableview with Textfield in swift?

Question

I want to make a table view with textfields in each cell,

I have a custom class in a swift file:

import UIKit

public class TextInputTableViewCell: U         


        

Answer 1

this method is init the cell,u have not model to save this datas,so

text = cell.textfield.text

is nothing! you can init var textString in viewcontroller,an inherit UITextFieldDelegate

optional func textFieldDidEndEditing(_ textField: UITextField)
{
     textString = _textField.text
}
optional func textFieldShouldReturn(_ textField: UITextField) -> Bool{
    return true
}

and cell.textField.text = textString

Answer 2

create a variable

var arrayTextField = [UITextField]()

after this in your func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell{} add

self.arrayTextField.append(textfield)

before returning cell, after this to display the values using

for textvalue in arrayTextField{
        println(textvalue.text)
    }

Answer 3

In your view controller become a UITextFieldDelegate

View Controller

class ViewController: UIViewController, UITableViewDataSource, UITableViewDelegate, UITextFieldDelegate {

    var allCellsText = [String]()

    func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {

        let cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as! CustomTableViewCell

        cell.theField.delegate = self // theField is your IBOutlet UITextfield in your custom cell

        cell.theField.text = "Test"

        return cell
    }

    func textFieldDidEndEditing(textField: UITextField) {
        allCellsText.append(textField.text!)
        println(allCellsText)
    }
}

This will always append the data from the textField to the allCellsText array.

So here is a way to do it using the suggestion of having a textfield array. It uses the tag of the textfield to ensure it does not get added multiple times when you scroll.

// Assumes that you have a label and a textfield as a part of you tableViewCell

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

    guard let cell = tableView.dequeueReusableCell(withIdentifier: "cell") as? BodyStatsTableViewCell else {
        return UITableViewCell()
    }
    cell.rowLabel.text = bodyTableArray[indexPath.row].rowTitle
    let tagValue = indexPath.row + 100
    var newRow = true
    for textvalue in arrayTextField{
        if textvalue.tag == tagValue {
            newRow = false
        }
    }
    if newRow {
        cell.rowTextField.tag = tagValue
        self.arrayTextField.append(cell.rowTextField)
        cell.rowTextField.text = bodyTableArray[indexPath.row].rowValue
    }
    return cell
}

// And then you cam get the values when you want to save with where tag - 100 will be the array index value to update

for textvalue in arrayTextField{ print(textvalue.text) }
