    <p>As per my understanding, you dont want to add the row where data is empty, so ill suggest you should perpare the sections data before telling the table view about the sections and rows. </p> <p>So, may be following code can help you..., i have tested it you just need to call the method "prepareSectionData" from "viewDidLoad" method and define the section arrays in .h file.</p> <pre><code>- (void) prepareSectionData { NSString *userEmail = @""; NSString *phoneNumber = @""; NSString *firstName = @""; NSString *gradYear = @""; NSString *graduate = @""; sectionOneArray = [[NSMutableArray alloc] init]; [self isEmpty:userEmail]?:[sectionOneArray addObject:userEmail]; [self isEmpty:phoneNumber]?:[sectionOneArray addObject:phoneNumber]; [self isEmpty:firstName]?:[sectionOneArray addObject:firstName]; sectionTwoArray = [[NSMutableArray alloc] init]; [self isEmpty:gradYear]?:[sectionTwoArray addObject:gradYear]; [self isEmpty:graduate]?:[sectionTwoArray addObject:graduate]; } -(BOOL) isEmpty :(NSString*)str{ if(str == nil || [[str stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]] length] == 0) return YES; return NO; } // Customize the number of sections in the table view. - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return 2; } // Customize the number of rows in the table view. - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { if(section == 0){ return [sectionOneArray count]; } else if (section == 1) { return [sectionTwoArray count]; } return 0; } // Customize the appearance of table view cells. - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; } // Configure the cell. if(indexPath.section == 0){ cell.textLabel.text = [sectionOneArray objectAtIndex:indexPath.row]; } else if (indexPath.section == 1) { cell.textLabel.text = [sectionTwoArray objectAtIndex:indexPath.row]; } return cell; } </code></pre>

    1. COBy the way, this code will return 0 rows, as all the variables are empty right now, just fill in with any string and see the result...

    3. COI have one doubt, now we have used two separate arrays of sectionOneArray, sectionTwoArray. Now i want to put the all the data's into the one array like, sectionArray. sectionArray[0] = ['name', 'email', 'phone' ] and sectionArray[1] = [ 'year', 'degree' ];. Is this any possible to use the single array to achieve this? Thanks.

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.
