Is there a simple way to format currency into string in iOS?
Solution 1
If you want it localized (ie the currency on the correct side of the price) it is a bit of a hassle.
NSDecimalNumber *price = [NSDecimalNumber decimalNumberWithString:@"1.99"];
NSLocale *priceLocale = [[[NSLocale alloc] initWithLocaleIdentifier:@"de_DE"] autorelease]; // get the locale from your SKProduct
NSNumberFormatter *currencyFormatter = [[[NSNumberFormatter alloc] init] autorelease];
[currencyFormatter setNumberStyle:NSNumberFormatterCurrencyStyle];
[currencyFormatter setLocale:priceLocale];
NSString *currencyString = [currencyFormatter internationalCurrencySymbol]; // EUR, GBP, USD...
NSString *format = [currencyFormatter positiveFormat];
format = [format stringByReplacingOccurrencesOfString:@"¤" withString:currencyString];
// ¤ is a placeholder for the currency symbol
[currencyFormatter setPositiveFormat:format];
NSString *formattedCurrency = [currencyFormatter stringFromNumber:price];
You have to use the locale you get from the SKProduct. Don't use [NSLocale currentLocale]!
Solution 2
The – productsRequest:didReceiveResponse:
method gives you back a list of SKProducts.
Each product contains a property priceLocale
which contains the local currency of the product for the current user.
You could use the following sample code (apple's) to format it:
NSNumberFormatter *numberFormatter = [[NSNumberFormatter alloc] init];
[numberFormatter setFormatterBehavior:NSNumberFormatterBehavior10_4];
[numberFormatter setNumberStyle:NSNumberFormatterCurrencyStyle];
[numberFormatter setLocale:product.priceLocale];
NSString *formattedString = [numberFormatter stringFromNumber:product.price];
Good luck!
Solution 3
The Swift Example:
var currencyFormatter = NSNumberFormatter()
currencyFormatter.numberStyle = NSNumberFormatterStyle.CurrencyStyle
currencyFormatter.locale = priceLocale //SKProduct->priceLocale
var currencyString = currencyFormatter.internationalCurrencySymbol
var format = currencyFormatter.positiveFormat
format = format.stringByReplacingOccurrencesOfString("¤", withString: currencyString)
currencyFormatter.positiveFormat = format
var formattedCurrency = currencyFormatter.stringFromNumber(price) //SKProduct->price
println("formattedCurrency: \(formattedCurrency)")//formattedCurrency: 0,89 EUR
Solution 4
Nice example I found here http://bendodson.com/weblog/2014/12/10/skproduct-localized-price-in-swift/
import StoreKit
extension SKProduct {
@objc func localizedPrice() -> String {
let formatter = NSNumberFormatter()
formatter.numberStyle = .CurrencyStyle
formatter.locale = self.priceLocale
return formatter.stringFromNumber(self.price)!
}
}
Solution 5
use formatter in this way or you can also customize it
NSNumberFormatter *numberFormatter = [[[NSNumberFormatter alloc] init] autorelease];
[numberFormatter setNumberStyle: NSNumberFormatterCurrencyStyle];
or like this
[formatter setFormat:@"USD ###.00"];
i think you can check the currency for the country and store that in string and give that to the formatter.

I need a way to format the price from NSNumber into a string like this: "USD 0.99", not "$ 0.99".
My game uses custom fonts, and they could not have the symbols for all the available App Store currencies like GBP. So I think it's better to roll-back to string representation of currency.
The method used should be absolutely OK for any currency that App Store supports.
