Códigos de país para plist

Em um de meus projetos, precisei de todos os códigos de país e seus nomes.

Usei este site:
http://countrycode.org/

Esta mágica 🙂 estrutura de análise HTML / XML:
https://github.com/topfunky/hpple

Aqui está o código:

NSURL *url = [NSURL URLWithString:@"http://countrycode.org/"];

NSData  * data      = [NSData dataWithContentsOfURL:url];

TFHpple * doc       = [[TFHpple alloc] initWithHTMLData:data];

NSArray *ar = [doc searchWithXPathQuery:@"/html/body/div/div[2]/div/div[2]/table/tbody"];
TFHppleElement *element = [ar objectAtIndex:0];

NSArray *children = [element children];

NSMutableDictionary *countryCodes = [[NSMutableDictionary alloc] init];

for (TFHppleElement *el in children) {
    for (TFHppleElement *elm in [el children]) {
        TFHppleElement *countryElement = [[[[el children] objectAtIndex:0] children] objectAtIndex:1];
        TFHppleElement *codeElement = [[el children] objectAtIndex:4];
        NSString *code = [[codeElement text] stringByReplacingOccurrencesOfString:@"u00a0" withString:@""];
        NSString *codeNW = [code stringByReplacingOccurrencesOfString:@" " withString:@""];
        NSString *codePlus = [NSString stringWithFormat:@"+%@", codeNW];
        [countryCodes setObject:codePlus forKey:[countryElement text]];
    }
}

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *path = [documentsDirectory stringByAppendingPathComponent:@"Countries.plist"];

// write plist to disk
[countryCodes writeToFile:path atomically:YES];
