Swift/UISwitch: how to implement a delegate/listener

Question

In my UITableViewController I have a custom cell which contains a switcher which is the following:

import Foundation
import UIKit

class SwitchCell: UITableV         


        

Answer 1

I have the solution in objective-c, it is the method that I use regularly:

-The Action of the switch must be in tableviewcontroller and not on the cell

-When You tap on the switch inside the action can do this to find the correct cell, then you can easily find the index or any other value that you need ...

- (IBAction)switchValueChanged:(UISwitch *)sender
{
    YourCellClass *cell = (YourCellClass *)[sender findSuperViewWithClass:[YourCellClass class]];
        etc....
    }

the method findSuperviewWithClass is a category on UIView

- (UIView *)findSuperViewWithClass:(Class)superViewClass
{
    UIView *superView = self.superview;
    UIView *foundSuperView = nil;

    while (nil != superView && nil == foundSuperView)
    {
        if ([superView isKindOfClass:superViewClass])
        {
            foundSuperView = superView;
        } else
        {
            superView = superView.superview;
        }
    }
    return foundSuperView;
}
