Retrieve textfield.text which is inside custom cell - ios

Question

I have tableview which has custom cells.
Each cell has 3 textfields: dayInWeek, startTime, endTime.
In below image, it has 2 rows. But user can click + button to add more rows.
If user click Submit button, I want to loop to every rows, collect 3 textfields data, and store in array or whatever.
Custom TableViewCell:
import UIKit
class RegularScheduleCell: UITableViewCell {
#IBOutlet weak var dayInWeek: UITextField!
#IBOutlet weak var startTime: UITextField!
#IBOutlet weak var endTime: UITextField!
override func awakeFromNib() {
super.awakeFromNib()
// Initialization code
}
}
And a view controller:
import UIKit
class RegularScheduleVC: UIViewController, UITableViewDelegate,UITableViewDataSource {
#IBOutlet weak var tableView: UITableView!
var numOfRow = 1
override func viewDidLoad() {
super.viewDidLoad()
tableView.dataSource = self
tableView.delegate = self
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return numOfRow
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cellIdentifier = "RegularScheduleCell"
let cell = tableView.dequeueReusableCell(withIdentifier: cellIdentifier, for: indexPath) as! RegularScheduleCell
return cell
}
func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath) {
if (editingStyle == UITableViewCellEditingStyle.delete) {
numOfRow -= 1
self.tableView.deleteRows(at: [indexPath], with: UITableViewRowAnimation.right)
tableView.reloadData()
}
}
func insertNewRow(_ sender: UIBarButtonItem) {
if numOfRow < 7 {
numOfRow += 1
tableView.reloadData()
}
}
override func setEditing(_ editing: Bool, animated: Bool) {
super.setEditing(editing, animated: animated)
tableView.setEditing(editing, animated: animated)
}
}
At this moment, I try to use UITextFieldDelegate
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cellIdentifier = "RegularScheduleCell"
let cell = tableView.dequeueReusableCell(withIdentifier: cellIdentifier, for: indexPath) as! RegularScheduleCell
cell.dayInWeek.delegate = self
cell.startTime.delegate = self
cell.endTime.delegate = self
return cell
and
func textFieldDidEndEditing(_ textField: UITextField) {
allCellsText.append(textField.text!) //allCellsText is an array
print(allCellsText)
}
so that when user finish editing, then add that data to array.
However, this does not satisfy my requirement, because:
on the same cell: can not know if the data is belong to dayOfWeek, or startTime, or endTime
on 2 different cells: can not know if data is belong to, let say, dayOfWeek of 1st cell or dayOfWeek of 2nd cell.
Therefore, How can I loop to all cells, get all 3 text fields data?
Thanks

Method 1:
Make an array of key pairs as-
var arrayOfKeyPairs = [[String:Any]]()
arrayOfKeyPairs.append(["header":"xx",
"value" : "",
“id”: "dsd",
"order" : 0])
We are just replacing the default values with user input values as-
func textFieldDidEndEditing(_ textField: UITextField) {
let center: CGPoint = textField.center
let rootViewPoint: CGPoint = textField.superview!.convert(center, to: tableView)
let indexPath: IndexPath = tableView.indexPathForRow(at: rootViewPoint)! as IndexPath
arrayOfKeyPairs[indexPath.row ]["value"] = textField.text//here you are appending(replacing) data to array
}
On click of submit button, cross check what you received as-
func tapsOnNext(){
self.view.endEditing(true)//for adding last text field value with dismiss keyboard
print(arrayOfKeyPairs)
}
Method 2:
We can get cell data by accessing the cell with particular indexpath as
func tapsOnNext(){
let indexpath = IndexPath(row: 0, section: 0)
let cell = tableView.cellForRow(at: indexPath) as! CustomTableViewCell
print(cell.myTextField.text)
}

Answer 2

You can get text of UITextField with adding target to UITextField
cell.YOUR_TEXTFIELD.addTarget(self, action: "textFieldDidChange:", forControlEvents: UIControlEvents.EditingChanged)
//EditingChanged is one of the events and will be fired whenever the user changes any character in that UITextField.
After that, you can call your function like this:
func textFieldDidChange(textField: UITextField) {
//your code
}
Don't forget to create class for UITableViewCell and to create IBOutlets of all your UITextField in that custom cell class

Answer 3

You can do it the following way.
First of all you can create an object for example "History"
make its properties like daysInWeek, startTime, endTime.
In your viewDidLoad method you define an array of Objects. Populate the data in the array, or save those objects of "History" that you created in this array.
Set the dataSource of the table view to this array.
in your method cellForRowAtIndexPath you can access the elements of the array you created above.
When you are tapping the plus button, you can create a new object of History, save this object in the array and reload the table view.
If you can share the git repo of this code, i will show how this is being done.

Simple code: On button click get cell data from cell's text field
let indexpath = IndexPath(row: 0, section: 1)
let cell = ItemtableView.cellForRow(at: indexPath) as! CustomTableViewCell
print("text \(cell.myTextField.text)")
