You have to implement the tableView methods that are

- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section

for section headers and for this this you also have to implement

- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section

By doing this your table data can be viewed in grouped style.

Use something like following to sort the contacts:

    NSArray* tempArray = [jsonData objectForKey:@"contacts"];
    NSSortDescriptor *sortDescriptor;
    sortDescriptor = [[[NSSortDescriptor alloc] initWithKey:@"first_name"
                                                 ascending:YES] autorelease];
    NSArray *sortDescriptors = [NSArray arrayWithObject:sortDescriptor];
    contactsArray = [[NSArray alloc] initWithArray:[tempArray  sortedArrayUsingDescriptors:sortDescriptors]];

From the use NSPredicate to pick the contacts and add them to section that you want.
