NSLocale localeIdentifier example ios


Returns the identifier for the receiver.
- (NSString *)localeIdentifier
Return Value of [NSLocale localeIdentifier]
The identifier for the receiver. This may not be the same string that the locale was created with, since NSLocale may canonicalize it.
Equivalent to sending objectForKey: with key NSLocaleIdentifier.
Example of [NSLocale localeIdentifier]
 NSArray *arr = [NSLocale preferredLanguages];
for (NSString *lan in arr) {
    NSLog(@"%@: %@ %@",lan, [NSLocale canonicalLanguageIdentifierFromString:lan], [[[NSLocale alloc] initWithLocaleIdentifier:lan] displayNameForKey:NSLocaleIdentifier value:lan]);
Example of [NSLocale localeIdentifier]
NSLocale *locale = [NSLocale currentLocale];

NSString *language = [locale displayNameForKey:NSLocaleIdentifier 
                                         value:[locale localeIdentifier]];

Example of [NSLocale localeIdentifier]
- (NSLocale *) findLocaleByCurrencyCode:(NSString *)_currencyCode
        NSArray *locales = [NSLocale availableLocaleIdentifiers];
        NSLocale *locale = nil;
        NSString *localeId;

        for (localeId in locales) {
                locale = [[[NSLocale alloc] initWithLocaleIdentifier:localeId] autorelease];
                NSString *code = [locale objectForKey:NSLocaleCurrencyCode];
                if ([code isEqualToString:_currencyCode])
                        locale = nil;

        /* For some codes that locale cannot be found, init it different way. */
        if (locale == nil) {
                NSDictionary *components = [NSDictionary dictionaryWithObject:_currencyCode

                localeId = [NSLocale localeIdentifierFromComponents:components];
                locale = [[NSLocale alloc] initWithLocaleIdentifier:localeId];
        return locale;
