    <p>I have a problem with a <code>UISwitch</code> in a tableview cell.</p> <p>This switch is normally in On position, then when a variable changes its value the switch go to the Off position but I have a problem like the switch in the second row:</p> <p><img src="https://i.stack.imgur.com/KWe0U.png" alt="enter image description here"></p> <p>This is the simple code into the cellForRowAtIndexPath section:</p> <pre><code>- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; tableView.backgroundColor = [UIColor clearColor]; tableView.opaque = NO; tableView.backgroundView = nil; [tableView setBackgroundColor:[UIColor colorWithPatternImage:[UIImage imageNamed:@"myImage.png"]]]; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier]; } if ([self.title isEqualToString:@"Test"]) {cell.textLabel.text = [self.tester objectAtIndex: [indexPath row]];cell.selectionStyle = UITableViewCellSelectionStyleNone; cell.accessoryType = UITableViewCellAccessoryNone; if (([indexPath row] == 5) || ([indexPath row] == 4)){ NSArray *segmentItems = [NSArray arrayWithObjects:@"Down", @"Up", nil]; UISegmentedControl *testSegmentedControl = [[UISegmentedControl alloc] initWithItems:segmentItems]; testSegmentedControl.autoresizingMask = UIViewAutoresizingFlexibleWidth; testSegmentedControl.segmentedControlStyle = UISegmentedControlStyleBar; testSegmentedControl.tintColor = [UIColor grayColor]; testSegmentedControl.frame = CGRectMake(160, 10, 150, 30); [testSegmentedControl setTag:[indexPath row]]; [[cell contentView] addSubview:testSegmentedControl]; [testSegmentedControl addTarget:self action:@selector(testing:) forControlEvents:UIControlEventValueChanged]; } else { mySwitch = [ [ UISwitch alloc ] initWithFrame: CGRectMake(200, 10, 0, 0) ]; mySwitch.tag = [indexPath row]; mySwitch.onTintColor = [UIColor grayColor]; if ([indexPath row] == 0){ if ([asd41 isEqualToString:@"False"]) mySwitch.on = NO; else mySwitch.on = YES; } if ([indexPath row] == 1){ if ([asd40 isEqualToString:@"False"]) mySwitch.on = NO; else mySwitch.on = YES; } if ([indexPath row] == 2){ if ([asd42 isEqualToString:@"False"]) mySwitch.on = NO; else mySwitch.on = YES; } if ([indexPath row] == 3){ if ([asd76 isEqualToString:@"False"]) mySwitch.on = NO; else mySwitch.on = YES; } [ cell addSubview: mySwitch ]; [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration: 0.2]; [mySwitch addTarget:self action:@selector(switch1:) forControlEvents:UIControlEventValueChanged];} } </code></pre>

    1. COYou are probably adding a switch over and over as the cell is reused. Only add a switch if you actually alloc/init the cell.

    2. CO@rmaddy Yes, you're right. In effect with '[self.tableView reloadData];' I add a switch on another one. How can I update the switch status without reload all the tableview?

    3. COThe problem isn't with calling `reloadData`. The problem is in `cellForRow...`. Only add a switch once per cell. Cells get reused. Don't add another switch for each reuse.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
