Saving TableView cells data (containing segment controller) using button - ios

Question

I'm tired of searching about what I want, so I will ask here and hope you guys help if possible.
I have a tableview contain segments in each cell and I want to save all cells segment using button [outside the tableview] so I can show them in another table later.
Here is my tableview
here is my view Controller:
import UIKit
class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
#IBOutlet weak var tableView: UITableView!
let arr = ["item 1",
"item 2",
"item 3"]
override func viewDidLoad() {
super.viewDidLoad()
tableView.register(CustomCell.self, forCellReuseIdentifier: "cell")
}
#IBAction func saveButtonAction(_ sender: UIButton) {
// I want to save the cells segmented control selectedSegmentIndex???
}
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
90
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return arr.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! CustomCell
cell.textView.text = arr[indexPath.row]
return cell
}
}
and here is my Custom Cell and it contain TextView and Segment Controller I tried to save the segments changes in array but I don't know what to do after lol:
import UIKit
class CustomCell: UITableViewCell {
let textView: UITextView = {
let tv = UITextView()
tv.translatesAutoresizingMaskIntoConstraints = false
tv.font = UIFont.systemFont(ofSize: 16)
tv.isEditable = false
return tv
}()
// var rowIndexPath: Int?
var segmentArray: [Int] = []
lazy var itemSegmentedControl: UISegmentedControl = {
let sc = UISegmentedControl(items: ["1", "2", "3"])
sc.translatesAutoresizingMaskIntoConstraints = false
sc.tintColor = UIColor.white
sc.selectedSegmentIndex = 0
sc.addTarget(self, action: #selector(handlePointChange), for: .valueChanged)
return sc
}()
let stackView: UIStackView = {
let sv = UIStackView()
sv.translatesAutoresizingMaskIntoConstraints = false
return sv
}()
#objc func handlePointChange() {
let segChange = itemSegmentedControl.titleForSegment(at: itemSegmentedControl.selectedSegmentIndex)!
segmentArray.append(Int(segChange)!)
}
override func awakeFromNib() {
super.awakeFromNib()
// Initialization code
}
override func setSelected(_ selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
stackView.addSubview(textView)
stackView.addSubview(itemSegmentedControl)
addSubview(stackView)
stackView.centerXAnchor.constraint(equalTo: self.centerXAnchor).isActive = true
stackView.centerYAnchor.constraint(equalTo: self.centerYAnchor).isActive = true
stackView.widthAnchor.constraint(equalToConstant: 400).isActive = true
stackView.heightAnchor.constraint(equalToConstant: 85).isActive = true
itemSegmentedControl.centerXAnchor.constraint(equalTo: self.centerXAnchor).isActive = true
itemSegmentedControl.topAnchor.constraint(equalTo: textView.bottomAnchor, constant: 5).isActive = true
itemSegmentedControl.widthAnchor.constraint(equalTo: textView.widthAnchor).isActive = true
itemSegmentedControl.heightAnchor.constraint(equalToConstant: 40).isActive = true
textView.rightAnchor.constraint(equalTo: self.rightAnchor, constant: -10).isActive = true
textView.topAnchor.constraint(equalTo: stackView.topAnchor).isActive = true
textView.widthAnchor.constraint(equalTo: stackView.widthAnchor).isActive = true
textView.heightAnchor.constraint(equalToConstant: 40).isActive = true
}
}
Regards and thanks.

Answer 1

First: in the ViewController I added the empty array:
// I moved the segment array from the custom cell class to here
var segmentArray: [Int:Int] = [:]
override func viewDidLoad() {
super.viewDidLoad()
// I made this array to store default state to the items segments
segmentArray = [0:0,1:0,2:0]
}
// with this func I can update the segmentArray
func getSegmentNumber(r: Int, s: Int) {
segmentArray[r] = Int(s)
}
#IBAction func saveButtonAction(_ sender: UIButton) {
// Here I can save the new state for the segment to the firebase or anywhere.
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! CustomCell
cell.textView.text = arr[indexPath.row]
// here to store the index path row
cell.rowIndexPath = indexPath.row
// you need to add the link because it won't work
cell.link = self
return cell
}
Second: in the Custom Cell Class:
// I removed the store array
var segmentArray: [Int] = [] // removed
// I made link to the ViewController
var link: ViewController?
// variable to get the index path row
var rowIndexPath: Int?
// here I can update the state of the segment using the link
#objc func handlePointChange() {
let segChange = itemSegmentedControl.selectedSegmentIndex
link?.getSegmentNumber(r: rowIndexPath!, s: segChange)
}
That worked for me, and I hope you got it.
If you need anything you can ask.
Again thanks to Kudos.
