    <p>I have a <code>UITableView</code> in iOS with a list of clients that I need to sort alphabetically.</p> <p>The sort button sorts my clients alphabetically:</p> <pre><code>-(void)prepareSortedClients { //Check if my clients are sorted, then create the index and clients if (!self.alphaKeys) { //No list of appropriate characters for side index, create it NSMutableSet *alphaSet = [[NSMutableSet alloc] init]; for ( RMClients *thisClient in self.clients ) { if ( thisClient.name &gt; 0 ) [alphaSet addObject:[thisClient.name substringToIndex:1]]; } NSArray *indexArray = [[alphaSet allObjects] sortedArrayUsingSelector:@selector(localizedCaseInsensitiveCompare:)]; self.alphaKeys = indexArray; } if (!self.sortedClients) { //Clients are not sorted, do it self.sortedClients = [[NSMutableDictionary alloc] init]; //Create a set of all the client objects NSSet *allClients = [NSSet setWithArray:self.clients]; //go through alpha keys and populate Dictionary with the appropriate clients for (NSString *thisAlphaKey in self.alphaKeys) { //get all clients starting with this key NSPredicate *predicate = [NSPredicate predicateWithFormat:@"SELF.name beginswith[c] %@",thisAlphaKey]; NSSet *filteredSet = [allClients filteredSetUsingPredicate:predicate]; //the filteredSet now contains only the clients starting with this letter. Now, sort them and set the sortedClients's corresponding key to this array [self.sortedClients setObject:[[filteredSet allObjects] sortedArrayUsingSelector: @selector(localizedCaseInsensitiveCompare:)] forKey:thisAlphaKey]; } } </code></pre> <p>This takes care of sorting and everything looks great; my clients are sorted according to the client title with the proper section and everything. The issue I am experiencing is that I have 4 buttons in each cell (it gives you additional info specific info about the company (overview, financials etc).</p> <p>Now my original list without it being sorted I get these buttons going to the proper place and displaying information about the client in that cell.</p> <p>Now in the alphabetical sort I get the sort for the client with the letter "A" directed to the proper client page... now if I click on one of the buttons for a specific client under the letter "B" I still get the first client under the letter "A".</p> <p>So I am not getting that sort for the remaining clients even though they are displayed there.</p> <p>Any idea where I messed up?</p> <p><strong>---Additional code--- (This is where I refer to the buttons in my code)</strong></p> <pre><code>- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { RMCustomClientCell *cell = [tableView dequeueReusableCellWithIdentifier:@"ClientCell"]; RMClients *client; if(!self.alphaMode){ client = [self.clients objectAtIndex:indexPath.row]; } else { NSString *key = [self.alphaKeys objectAtIndex:indexPath.section]; NSArray *specificClients = [self.sortedClients objectForKey:key]; client = [specificClients objectAtIndex:indexPath.row]; } cell.financialDetailsButton.tag = indexPath.row; cell.overviewDetailsButton.tag = indexPath.row; cell.pressReleaseDetailsButton.tag = indexPath.row; cell.eventsDetailsButton.tag = indexPath.row; cell.nameLabel.text = client.name; cell.symbolLabel.text = client.symbol; [cell.logoView setImageWithURL:[NSURL URLWithString:client.logoURL] placeholderImage:[UIImage imageNamed:@"placeholder.png"]]; return cell; } </code></pre>

    2. COSounds like the data in each section is not grouped properly. Can you post the code that shows how you reload the table's data after sorting the clients?

    3. COLet me guess: these buttons are stored in the other array than your clients? And when you sort your clients array you reload the `UITableView`? So the text there comes from that **sorted** array of clients and corresponding 4 buttons come from the array(s) that is(are) unsorted. Am I right?

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.
