Setting it as the accessoryView is usually the way to go. You can set it up in

tableView: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" );
}
