//    search = [search uppercaseString];

    NSLog(@"Array count233 : %d", [menuArray count]);



    NSLog(@"Array count237 : %d", [menuArray count]);

    NSLog(@"Search String : %@", search);
    if ([search isEqualToString:@""]) {

    }
    else {

        [tableMenuArray removeAllObjects];

            for (int i = 0; i < [menuArray count]; i++) {
                if ([[[menuArray objectAtIndex:i] itemName] hasPrefix:search]) {
                    [tableMenuArray addObject:[menuArray objectAtIndex:i]];

                }

If you uncomment the 2nd line, then change this line –

if ([[[menuArray objectAtIndex:i] itemName] hasPrefix:search])

…to –

if ([[[[menuArray objectAtIndex:i] itemName] uppercaseString] hasPrefix:search])

Otherwise you’re comparing all-uppercase to normally-cased words. Hope this sorts it for you!
