Setting it as the accessoryView is usually the way to go. You can set it up intableView:cellForRowAtIndexPath: You may want to use target/action to so something when the switch is flipped. Like so:

 

 

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    switch( [indexPath row] ) {
        case MY_SWITCH_CELL: {
            UITableViewCell* aCell = [tableView dequeueReusableCellWithIdentifier:@"SwitchCell"];
            if( aCell == nil ) {
                aCell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:@"SwitchCell"] autorelease];
                aCell.textLabel.text = @"I Have A Switch";
                aCell.selectionStyle = UITableViewCellSelectionStyleNone;
                UISwitch *switchView = [[UISwitch alloc] initWithFrame:CGRectZero];
                aCell.accessoryView = switchView;
                [switchView setOn:NO animated:NO];
                [switchView addTarget:self action:@selector(switchChanged:) forControlEvents:UIControlEventValueChanged];
                [switchView release];
            }
            return aCell;
        }
        break;
    }
    return nil;
}

- (void) switchChanged:(id)sender {
    UISwitch* switchControl = sender;
    NSLog( @"The switch is %@", switchControl.on ? @"ON" : @"OFF" );
}
