    <p>How can I retrieve the current header section name from an <code>NSTableViewCell</code> item?</p> <p>Currently I have a method called <code>configureCell</code> which determines how to style the custom cell I have. This data comes from a pList file.</p> <pre><code>-(void)configureCell:(UITableViewCell *)tableViewCell forIndexPath:(NSIndexPath *)indexPath{ UILabel *label; UIView *backView; // NSString *country = [self tableView: tableViewCell titleForHeaderInSection:indexPath.section]; NSString *fatPercent = [[self.milkTypes valueForKey:@"Finland"] objectAtIndex:indexPath.row]; label = (UILabel *)[tableViewCell viewWithTag:1]; label.text = @"Fat Percent test"; backView = (UIView *)[tableViewCell viewWithTag:2]; backView.backgroundColor = [self colorWithHexString: fatPercent]; } </code></pre> <p>Where I've commented out the line for <code>*country</code> I need to retrieve the current section I'm in. Currently it's statically set to <code>Finland</code> which is the array name from the pList.</p> <p>For a better understanding on how my code is laid out, here is the majority of the Table Controller.</p> <pre><code> - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return [self.milkTypes count]; } - (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section { return [[self.milkTypes allKeys] objectAtIndex:section]; } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { NSString *country = [self tableView:tableView titleForHeaderInSection:section]; return [[self.milkTypes valueForKey:country] count]; } -(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { NSString *cellIdentifier; UITableViewCell *cell; cellIdentifier = [NSString stringWithFormat:@"MilkCell"]; cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier]; if (cell==nil) { cell = [self tableViewCellWithReuseIdentifier:cellIdentifier forIndexPath:indexPath]; } [self configureCell:cell forIndexPath:indexPath]; cell.selectionStyle = UITableViewCellSelectionStyleNone; return cell; } -(UITableViewCell *)tableViewCellWithReuseIdentifier:(NSString *)identifier forIndexPath:(NSIndexPath *)indexPath{ CGRect rect; UILabel *label; UIView *backView; UITableViewCell *cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:identifier] autorelease]; float center = (float) (40-20)/2; rect = CGRectMake(15, center, 270, 20); label = [[UILabel alloc] initWithFrame:rect]; label.autoresizingMask = UIViewAutoresizingFlexibleRightMargin | UIViewAutoresizingFlexibleWidth; label.tag = 1; label.backgroundColor = [UIColor clearColor]; label.textColor = [UIColor blackColor]; [cell.contentView addSubview:label]; [label release]; rect = CGRectMake(280, 10, 20, 40-20); backView = [[UIView alloc] initWithFrame:rect]; backView.autoresizingMask = UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleWidth; backView.backgroundColor = [UIColor clearColor]; backView.tag = 2; [cell.contentView addSubview:backView]; [backView release]; return cell; } -(void)configureCell:(UITableViewCell *)tableViewCell forIndexPath:(NSIndexPath *)indexPath { UILabel *label; UIView *backView; // NSString *country = [self tableView: tableViewCell titleForHeaderInSection:indexPath.section]; NSString *fatPercent = [[self.milkTypes valueForKey:@"Sweden"] objectAtIndex:indexPath.row]; label = (UILabel *)[tableViewCell viewWithTag:1]; label.text = @"Fat Percent test"; backView = (UIView *)[tableViewCell viewWithTag:2]; backView.backgroundColor = [self colorWithHexString: fatPercent]; } </code></pre>

    1. CODo you not have an array of section headers anyway that you can select from using the indexPath.section value?

    2. COStupidly no. I'm kind of new to iOS development and trying to get my head round some of the differences that I'm used to. Examples of storing sections in array?

Guidance
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.
