json convert to section table

Example:
json =  (
        {
        author = "Jeff Hawkins";
        description = "Jeff Hawkins;
        title = "On Intelligence";
    },
        {
        author = "Jack Kerouac";
        description = "The most;
        title = "On The Road";
    },
        {
        author = "Daniel Quinn";
        description = "Winner of the;
        title = Ishmael;
    },
        {
        author = "Frank Herbert";
        description = "This Hugo ;
        title = Dune;
    }
)

    NSMutableArray *books;

    NSMutableDictionary *sections;

//after return json value

self.sections = [[NSMutableDictionary alloc] init];

    

    BOOL found;

    

    // Loop through the books and create our keys

    for (NSDictionary *book in self.books)

    {        

        NSString *c = [[book objectForKey:@"title"] substringToIndex:1];

        

        found = NO;

        

        for (NSString *str in [self.sections allKeys])

        {

            if ([str isEqualToString:c])

            {

                found = YES;

            }

        }

        

        if (!found)

        {     

            [self.sections setValue:[[NSMutableArray alloc] init] forKey:c];

        }

    }

        

    // Loop again and sort the books into their respective keys

    for (NSDictionary *book in self.books)

    {

        [[self.sections objectForKey:[[book objectForKey:@"title"] substringToIndex:1]] addObject:book];

    }    

    

  // Sort each section array

    for (NSString *key in [self.sections allKeys])

    {

        [[self.sections objectForKey:key] sortUsingDescriptors:[NSArray arrayWithObject:[NSSortDescriptor sortDescriptorWithKey:@"title" ascending:YES]]];

    } 

// Table view

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView 

{

    return [[self.sections allKeys] count];

}

- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section

{    

    return [[[self.sections allKeys] sortedArrayUsingSelector:@selector(localizedCaseInsensitiveCompare:)] objectAtIndex:section];

}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section 

{

    return [[self.sections valueForKey:[[[self.sections allKeys] sortedArrayUsingSelector:@selector(localizedCaseInsensitiveCompare:)] objectAtIndex:section]] count];

}

//Search array for section side bar

- (NSArray *)sectionIndexTitlesForTableView:(UITableView *)tableView {

    return [[self.sections allKeys] sortedArrayUsingSelector:@selector(localizedCaseInsensitiveCompare:)];

}

// 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:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease];

    }

    

    NSDictionary *book = [[self.sections valueForKey:[[[self.sections allKeys] sortedArrayUsingSelector:@selector(localizedCaseInsensitiveCompare:)] objectAtIndex:indexPath.section]] objectAtIndex:indexPath.row];

    

    cell.textLabel.text = [book objectForKey:@"title"];    

    cell.detailTextLabel.text = [book objectForKey:@"description"];

    return cell;

}
