Matthias Bauch answer in swift:

var formatter = NSNumberFormatter()
    formatter.numberStyle = NSNumberFormatterStyle.CurrencyStyle
    formatter.locale = product!.priceLocale
var currencyString = "\(formatter.stringFromNumber(product!.price)!)"

Answer 2

I used these keys to extract currency symbols/codes from locales

NSLocale *theLocale = [NSLocale currentLocale];
NSString *symbol = [theLocale objectForKey:NSLocaleCurrencySymbol];
NSString *code = [theLocale objectForKey:NSLocaleCurrencyCode];

Answer 3

create macro first then use it
#define CURRENCY_SYMBOL [[NSLocale currentLocale] objectForKey:NSLocaleCurrencySymbol]

NSLog(@"%@ %.2f",CURRENCY_SYMBOL,25.50);

Answer 4

I used below code in my app to retrieve local curreny sign and find the delimiters. I will help you,

NSDecimalNumber *amount = [NSDecimalNumber decimalNumberWithString:@"50.00"];
NSNumberFormatter *currencyFormat = [[NSNumberFormatter alloc] init];
NSLocale *locale = [NSLocale currentLocale];
[currencyFormat setNumberStyle:NSNumberFormatterCurrencyStyle];
[currencyFormat setLocale:locale];
NSLog(@"Amount with symbol: %@", [currencyFormat stringFromNumber:amount]);//Eg: $50.00
NSLog(@"Current Locale : %@", [locale localeIdentifier]);//Eg: en_US

Thanks.

Here is an example in Swift 5:

let formatter = NumberFormatter()
formatter.formatterBehavior = .behavior10_4
formatter.numberStyle = .currency
formatter.locale = product.priceLocale
print(formatter.string(from: products![0].price)

Answer 6

In most cases the currency symbol won't be enough. For example, in Germany we write our prices like this: 1,99€ but people in the US use $1.99. There are three differences in the string. The currency symbol, the position of it and the separator.

If you want to do it right you should use a NSNumberFormatter. It takes care of all the differences between currency formats. And it does it much better than you. Because it does it for all currencies, not just for the 4 main currencies you want to support.

NSNumberFormatter *formatter = [[NSNumberFormatter alloc] init];
[formatter setNumberStyle:NSNumberFormatterCurrencyStyle];
[formatter setLocale:[NSLocale currentLocale]];
NSString *localizedMoneyString = [formatter stringFromNumber:myCurrencyNSNumberObject];

If you want to use this for in app purchase you can't rely on the users current locale, because it is possible to use a US-based account on a device with a DE (german) locale. And the price of your item (actual price is 0,79€ in Germany) would show as 0,99€ (because it costs $0.99 in the US). This would be wrong. You get a localized price already from the app store, there is no need to do calculations on your own.
And you get a price and a priceLocale for each of your SKProducts.

You would get the correct formatted currency string like this:

SKProduct *product = [self.products objectAtIndex:indexPath.row];
NSNumberFormatter *formatter = [[[NSNumberFormatter alloc] init] autorelease];
[formatter setNumberStyle:NSNumberFormatterCurrencyStyle];
[formatter setLocale:product.priceLocale];
currencyString = [formatter stringFromNumber:product.price];

EDIT: since you specifically asked for the currency code.

You can get it with NSString *currencyCode = [formatter currencyCode]; This will give you the currency code according to ISO 4217. AUD, USD, EUR and so on.
