UISwitch in a UITableView cell

Question

How can I embed a UISwitch on a UITableView cell? Examples can be seen in the settings menu.

My current solution:

UISwitch *mySwitch = [[[UISwitch alloc] init] autorelease]; cell.accessoryView = mySwitch; 

Answer 1

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 do 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" ); }
