    <p>You have your table structure in a NSArray, so I would suggest you to create a NSDictionary for each row that should have a segmented control and add that to the table structure NSArray</p> <p>You'll need three objects inside the dictionary. A title, a NSArray with the names of the segments, and you need a key you use to set and get the selected index.</p> <p>I did something similar for the settings viewcontroller in some of my apps. This is how the NSDictionary looks like:</p> <pre><code>[NSDictionary dictionaryWithObjectsAndKeys: @"Value of Foo", kSettingsLabel, // for the textLabel [UISegmentedControl class], kSettingsView, // which UIControl @"foo", kSettingsKey, // the key for setValue:forKey: and valueForKey: [NSArray arrayWithObjects: @"Green", @"Round", @"Auto",nil], kSettingsValue, // the titles of the segments nil] </code></pre> <p>This is how I set up the UISegmentedControls in my tableview:</p> <pre><code>NSDictionary *dictionary = [[self.dataSourceArray objectAtIndex:indexPath.section] objectAtIndex:indexPath.row]; // omitted: check in the dictionary which cell we need... (I wrote it that it can use almost all UIControls) // omitted: dequeue a cell with a UISegmentedControl ... // configure cell: NSArray *segmentTitles = [dictionary objectForKey:kSettingsValue]; UISegmentedControl *segment = (UISegmentedControl *)[cell viewWithTag:kTagSegment]; [segment removeAllSegments]; for (NSString *segmentName in segmentTitles) { // if index is higher than number of indexes title is inserted at last available index. // so first object in array is placed at first position in segmentcontrol [segment insertSegmentWithTitle:segmentName atIndex:1000 animated:NO]; } [segment setSelectedSegmentIndex:[[self valueForKey:[dictionary valueForKey:kSettingsKey]] intValue]]; //omitted: setup cell title ... and return cell </code></pre> <p>The UISegmentedControl is connected to a value changed action that looks like this:</p> <pre><code>NSIndexPath *indexPath = [self.settingsTable indexPathForCell:(UITableViewCell *)[[sender superview] superview]]; if (indexPath == nil) return; NSDictionary *dictionary = [[self.dataSourceArray objectAtIndex:indexPath.section] objectAtIndex:indexPath.row]; if ([sender isKindOfClass:[UISegmentedControl class]]) { [self setValue:[NSNumber numberWithInt:((UISegmentedControl *)sender).selectedSegmentIndex] forKey:[dictionary valueForKey:kSettingsKey]]; } </code></pre> <p>and of course you need the setter and getter for the specified key too:</p> <pre><code>- (NSNumber *)foo { return [NSNumber numberWithInt:someValue]; } - (void)setFoo:(NSNumber *)n { someValue = [n intValue]; } </code></pre> <p>You could synthesize them but I wanted to have int value in my class instead of NSNumbers, so I wrote the setter and getter myself.</p> <hr> <p>The big advantage of this is that it is completely dynamic. If you want to rearrange cells just shift them around in the array (I use a plist to make that even easier). </p> <p>It's a little bit complicated when you use it for the first time, but it gets clear pretty fast. And you don't want five different .xibs and five different UISegmentedControls in your class interface. </p>

    1. COSo this way, I don't use any IB at all, right? This looks slightly more complex then what I'm looking for, as these rows will never need to be dynamic. I appreciate the effort of posting the code (this might actually get used in a different view in the app), but is there a different method you could recommend for a static table?

    2. COI used one .xib which has like 10 UITableViewCells for all the different cells I need. And to be honest with a static table I would do it almost the same way. Create a .xib with a cell layout and create the segment titles in code. When this is static there is no need for the dictionary or the key-value access. A `if (row == 1) /* setup cell */` with hardcoded values would be sufficient.

    3. COGreat! In my case, I'd use 'if (section == 1) /* setup cell*/, but the idea remains the same. So then do something like [this blog post?](http://clingingtoideas.blogspot.com/2011/03/uitableview-how-to-part-4-xib-based.html) What's the advantage of setting up the segment titles in code instead of in IB? If I'm messing with IB anyway, wouldn't I save myself some coding by setting them in IB, or am I missing something here?

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.
