Switches in Tableviews

I have the following custom UITableViewCell:

enter image description here

I want my view controller to be notified when somebody flips a cell's switch in order to update my model. I've tried using the table view's delegate methods (didSelect, didFinishEditing, didHighlight, etc.) but none of them are called upon this action. Is there any way to do what I want to do? Somebody please help.

Solution

  • actually your UISwitch has added to accessoryView of UITableViewCell, so do like on cellforRowAtIndex

    var switchView = UISwitch(frame: CGRect.zero)
aCell.accessoryView = switchView
lightSwitch.tag = indexPath.row
switchView.setOn(false, animated: false)
switchView.addTarget(self, action: #selector(switchChanged(_:), for: .valueChanged)

    and get the action of UISwitch as 

    func switchChanged(_ sender: UISwitch) {

    print("which switch is \(sender.tag)")
    print("The switch is \(sender?.on ? "ON" : "OFF")")
}
