Table view check box not accepting action for index 0 - ios

Question

I have a table view, in which I have the items with check boxes. Users can select any items (multiselection also) and they can press the Proceed button to pay.
I was using a button as a check box. So if the user presses the button, or they select a table row, both cases are handled the function.
So now, my proceed buton starts as disabled. Whenever the user presses any items using the didSelectRowAt method or check box button action, only then the Proceed button will be enabled.
But now, whenever I press the first item or the first check box button, my proceed button is not getting enabled. If I press the second item or the second check box, it works. I don't know why.
Here is my code of didSelectRowAt and my check box button action code:
#Updated:
var selectedIndexPathArray = Array<NSIndexPath>()
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "itemcell", for: indexPath) as! itemTableViewCell
cell.checkboxBtn.isUserInteractionEnabled = false
if selectedIndexPathArray.contains(indexPath as NSIndexPath) {
cell.checkboxBtn.setImage(UIImage(named: "enabled"), for: .normal)
proceedbutton.isUserInteractionEnabled = true
} else {
cell.checkboxBtn.setImage(UIImage(named: "disabled"), for: .normal)
proceedbutton.isUserInteractionEnabled = false
}
return cell
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
if selectedIndexPathArray.contains(indexPath as NSIndexPath) {
let index = selectedIndexPathArray.index(of: indexPath as NSIndexPath)
selectedIndexPathArray.remove(at: index!)
} else {
selectedIndexPathArray.append(indexPath as NSIndexPath)
}
tableView.reloadData()
}
Thanks in advance!

Answer 1

Yes because first time if you click on button then proceedbutton will be called and at that time selectedIndexPathArray will have no any value means nil.
So first time your else part will be executed.
.
.
.
else {
selectedIndexPathArray.append(indexPath! as NSIndexPath)
cell?.checkboxBtn.setImage(UIImage(named: "disabled"), for: .normal)
proceedbutton.isUserInteractionEnabled = false
}
And when you press agin then your if condition will be true so it will be enable

Answer 2

Try this on your if-else condition on your proceed() function.
if selectedIndexPathArray.contains(indexPath! as NSIndexPath) {
electedIndexPathArray.remove(at: index!)
cell?.checkboxBtn.setImage(UIImage(named: "disabled"), for: .normal)
proceedbutton.isUserInteractionEnabled = false
}
else {
selectedIndexPathArray.append(at: index!)
cell?.checkboxBtn.setImage(UIImage(named: "enabled"), for: .normal)
proceedbutton.isUserInteractionEnabled = true
}

Remove selector for button in cell and default set userInteraction for button is false.No need to set it everytime. Perform everything on didSelectRow.
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: itemscell, for: indexPath) as! itemsTableViewCell
cell?.checkboxBtn.isUserInteractionEnabled = false
if selectedIndexArray.contains(indexPath.row) {
cell.checkboxBtn.setImage(UIImage(named: "enabled"), for: .normal)
proceedbutton.isUserInteractionEnabled = true
} else {
cell.checkboxBtn.setImage(UIImage(named: "disabled"), for: .normal)
proceedbutton.isUserInteractionEnabled = false
}
return cell
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
if selectedIndexArray.contains(indexPath.row) {
let index = selectedIndexPathArray.index(of: indexPath.row)
selectedIndexArray.remove(at: index!)
} else {
selectedIndexArray.append(indexPath.row)
}
tableView.reloadData()
}
