How to do the multiple checkmark in tableview. I need to select the multiple checkmark in tableview and what are the checkmarks I need to select to place the multiple values in label.
Example player1,player2,player3 in label
here is my code
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
// #warning Incomplete method implementation.
// Return the number of rows in the section.
return TypeOfAccountArray.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
// let cell = tableView.dequeueReusableCellWithIdentifier("reuseIdentifier", forIndexPath: indexPath) as! UITableViewCell
let cell:TypeofAccountCell=tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! TypeofAccountCell
cell.Uertype_lbl.text=TypeOfAccountArray[indexPath.row]
cell.selectionStyle = UITableViewCellSelectionStyle.none;
cell.Uertype_lbl.font = UIFont(name:"Roboto-Regular", size:13)
cell.Uertype_lbl.adjustsFontSizeToFitWidth = true
if (selectedIndex == indexPath as NSIndexPath?) {
cell.checkmarkbtn.setImage(UIImage(named: "checkmark.png"),for:UIControlState.normal)
} else {
cell.checkmarkbtn.setImage(UIImage(named: "uncheckmark.png"),for:UIControlState.normal)
}
// Configure the cell...
return cell
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
tableView.deselectRow(at: indexPath as IndexPath, animated: true)
let row = indexPath.row
print(TypeOfAccountArray[row])
selectedIndex = indexPath as NSIndexPath?
self.Type_of_account_txt.text = (TypeOfAccountArray[row])
self.Type_account_view.isHidden = true
tableView.reloadData()
}

Answer 1

Change your selectedindex to hold array of index path var selectedIndexes = [IndexPath](), on your cell xib, set your checkmark image on button selected stated and uncheckmark image on normal status and use the below code.
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return TypeOfAccountArray.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell:TypeofAccountCell=tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! TypeofAccountCell
cell.Uertype_lbl.text=TypeOfAccountArray[indexPath.row]
cell.selectionStyle = UITableViewCellSelectionStyle.none;
cell.Uertype_lbl.font = UIFont(name:"Roboto-Regular", size:13)
cell.Uertype_lbl.adjustsFontSizeToFitWidth = true
// Configure the cell...
return cell
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
tableView.deselectRow(at: indexPath as IndexPath, animated: true)
let cell:TypeofAccountCell=tableView.cellForRow(at: indexPath) as! TypeofAccountCell
if selectedIndexes.contains(indexPath)
{
cell.checkmarkbtn.isSelected = false
if let index = selectedIndexes.index(of: indexPath) {
selectedIndexes.remove(at: index)
}
}
else
{
cell.checkmarkbtn.isSelected = true
selectedIndexes.append(indexPath)
}
}
self.Type_of_account_txt.text = ""
for element in selectedIndexes
{
self.Type_of_account_txt.text = (self.Type_of_account_txt.text ?? "") + "\(TypeOfAccountArray[element.row]) ,"
}
if (selectedIndexes.count > 0)
{
self.Type_of_account_txt.text = self.Type_of_account_txt.text?.substring(to: (self.Type_of_account_txt.text?.index(before: (self.Type_of_account_txt.text?.endIndex)!))!)
}
}

you need to follow this step :
In didSelectRowAt, you need to add and remove indexpath in array for multiple checkmark.
Now , in cellForRowAtIndexPath you need to check that current
indexPath consist in array .
if (![arrIndexPath containsObject: indexPath]) {
// do something
cell.checkmarkbtn.setImage(UIImage(named: "checkmark.png"),for:UIControlState.normal)
}
