Answer 1

NSNumberFormatter * formatter = [NSNumberFormatter new];
formatter.numberStyle = NSNumberFormatterCurrencyStyle;

NSString * localeIde = [NSLocale localeIdentifierFromComponents:@{NSLocaleCurrencyCode: currencyCode}];
formatter.locale = [NSLocale localeWithLocaleIdentifier:localeIde];

NSString * symbol = formatter.currencySymbol;

Answer 2

Swift

let locale = NSLocale(localeIdentifier: currencyCode)
let currencySymbol = locale.displayName(forKey: .currencySymbol, value: currencyCode) ?? currencyCode
print("Currency symbol: \(currencySymbol)")

Answer 3

This code works charm in my project. I will share this to you all.

NSString *currencyCode = @"EUR";
    NSLocale *locale = [[[NSLocale alloc] initWithLocaleIdentifier:currencyCode] autorelease];
    NSString *currencySymbol = [NSString stringWithFormat:@"%@",[locale displayNameForKey:NSLocaleCurrencySymbol value:currencyCode]];
    NSLog(@"Currency Symbol : %@", currencySymbol);

Thanks.

One way is to start with a valid locale (e.g. the user current locale) and then override the currency code. Simple and efficient and allows you to use the newly constructed locale to configure a currency formatter in order to display a string according to the user's locale preferences:

NSLocale* locale = [NSLocale currentLocale];
if (_currencyCode) {
    NSMutableDictionary* components = [[NSLocale componentsFromLocaleIdentifier:locale.localeIdentifier] mutableCopy];
    components[NSLocaleCurrencyCode] = _currencyCode;
    locale = [[NSLocale alloc] initWithLocaleIdentifier:[NSLocale localeIdentifierFromComponents:components]];
}
return locale.currencySymbol;

Answer 5

NSLocale will happily tell you the currency symbol used by a particular locale:

[locale objectForKey:NSLocaleCurrencySymbol];

It'll also tell you the currency code:

[locale objectForKey:NSLocaleCurrencyCode];

So all you have to do now is look up the locale that corresponds to a given code. There's no built-in method (that I'm aware of) to do this directly, so loop through all the known locales and pick the one that matches. @Umka's answer has a good example of this in the -findLocaleByCurrencyCode: method.

You could optimise the process by building your own lookup table, rather than iterating through all locales each time. You may need to handle the possibility of duplicate currency codes too, which would require some heuristic for deciding which is the most likely locale.

NSNumberFormatter *currencyFormatter = [[NSNumberFormatter alloc] init];
    [currencyFormatter setNumberStyle:NSNumberFormatterCurrencyStyle];

this is for US currency style

NSNumberFormatter *numberFormatter = [[[NSNumberFormatter alloc] init] autorelease];
    //[numberFormatter setCurrencySymbol:@"Rs"];        
    [numberFormatter setNumberStyle:@"en_IN"];
