How to get checked cells from tableview? - ios

Question

I've managed to create cells and have them check select and deselect. How do I get the string names of the cells and how do I keep them checked or unchecked upon button click. Say, for example, if I want to get only the checked cells and saved them to a database upon clicking the button and next time I open the tableview they should be selected/deselected.
import UIKit
class CellsViewController: UITableViewController {
// Creating cells with code
let activities = ["Jumping", "History", "Reading", "Football", "Nightlife", "Hiking", "Spa"]
// Function to figure out how many rows we need depending on the lenght of the list
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return activities.count
}
// returns the cell name and puts it in the table view controller
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath)
cell.textLabel?.text = activities[indexPath.row]
return cell
}
// checks and unchecks the given cell based on user click
override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
if tableView.cellForRow(at: indexPath)?.accessoryType == UITableViewCellAccessoryType.checkmark{
tableView.cellForRow(at: indexPath)?.accessoryType = UITableViewCellAccessoryType.none
}else{
tableView.cellForRow(at: indexPath)?.accessoryType = UITableViewCellAccessoryType.checkmark
}
}
#IBAction func saveButton(_ sender: Any) {
// Retrieve the checked cells and do something
// With them once the button is clicked
}
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}

// hi , give tag for that button , by using that tag u need to maintatin selected data in your array of table datasource
let activities = [["name": "Jumping", "isSelected": "NO"], ....]
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath)
cell.textLabel?.text = activities[indexPath.row]["name"]
cell.btnSelect.tag = indexPath.row
if activities[indexPath.row]["name"] as String == "Yes" {
cell.btnSelect.isSelected = true
} else {
cell.btnSelect.isSelected = false
}
return cell
}
#IBAction func saveButton(_ sender: Any) {
// Retrieve the checked cells and do something
// With them once the button is clicked
saveButton.isSelected = !saveButton.isSelected
let dicdetails = activities[sender.tag]
if saveButton.isSelected {
dicdetails["isSelected"] = "YES"
} else {
dicdetails["isSelected"] = "No"
}
activities[sender.tag] = dicdetails
}
