Objective c - Best practice to handle a button touch event for a button of a custom UITableViewCell

What is best practice to handle a button touch event for a button of a custom UITableViewCell?

my classes: MyViewController, MyCustomCell

I can think of three options:

First option- Have the button as a property of MyCustomCell, and then add a target to it in the MyViewController .m file with MyViewController as the target.

MyViewController .m file

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"customCell";

    MyCustomCell *cell = (MyCustomCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
    cell = [[[MyCustomCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];

    [cell.theButton addTarget:self
                       action:@selector(theButtonTapped:)
             forControlEvents:UIControlEventTouchUpInside];
    }

    // Configure the cell...    
    [self configureCell:cell atIndexPath:indexPath];

    return cell;
}

- (void)theButtonTapped:(UIButton *)sender
{
    MyCustomCell *selectedCell = (MyCustomCell *)sender.superview;

    if (selectedCell) {
        NSIndexPath *indexPath = [self.tableView indexPathForCell:selectedCell];
        MyModel *selectedModel = [self.model objectAtIndex:indexPath.row]; 

        // do something with the model...
    }
}

Second option- If the custom cell was made in IB, Set the nib File's Owner to be MyViewController, implement buttonTapped: method in MyViewController and connect the button's Touch Up Inside event to the buttonTapped: method.

Third option- if the custom cell wasn't made in IB, add a target to the button in the MyCustomCell .m file with
