Take a look at the UITableViewDataSource methods 

- (NSArray *)sectionIndexTitlesForTableView:(UITableView *)tableView
- (NSInteger)tableView:(UITableView *)tableView sectionForSectionIndexTitle:(NSString *)title atIndex:(NSInteger)index

you need to return an array with the titles for the various sections that will appear on the right. For instance:

- (NSArray *)sectionIndexTitlesForTableView:(UITableView *)tableView
{
    return @[@"A",@"B",@"C"];
}

and

- (NSInteger)tableView:(UITableView *)tableView sectionForSectionIndexTitle:(NSString *)title atIndex:(NSInteger)index
{
    return index;
}

return the index of the section to scroll to once the index on the right is tapped. You have to handle with sorting yourself, all the indexes do is scrolling to a certain section when an index on the right is tapped.
