NSNumberFormatter Currency Without Symbol?

Question

I am using NSNumberFormatter to get a currency value from a string and it works well.

I use this code to do so:

NSNumberFormatter *nf = [[NSNumberFormatter alloc] init];
    [nf setNumberStyle:NSNumberFormatterCurrencyStyle];
    NSString *price = [nf stringFromNumber:[NSNumber numberWithFloat:[textField.text floatValue]]];

However, it always gives me a currency symbol at the start of the string. Rather than doing it manually form my given string, can I not somehow have the formatter not give the string any currency symbol?

Mind that it won't always be at the start - for Euro prices you will have something like 12,34€ — ATV, May 05 '14 at 05:54

Yes, after you set the style, you can tweak specific aspects:

NSNumberFormatter *nf = [[NSNumberFormatter alloc] init];
[nf setNumberStyle:NSNumberFormatterCurrencyStyle];
[nf setCurrencySymbol:@""]; // <-- this
NSDecimalNumber* number = [NSDecimalNumber decimalNumberWithString:[textField text]];
NSString *price = [nf stringFromNumber:number];

Just as some advice, you should probably use a number formatter to read the string value, especially if a user is entering it (as suggested by your code). In this case, if the user enters locale-specific formatting text, the generic -floatValue and -doubleValue type methods won't give you truncated numbers. Also, you should probably use -doubleValue to convert to a floating point number from user-entered text that's a currency. There's more information about this in the WWDC'12 developer session video on internationalization.

Edit: Used an NSDecimalNumber in the example code to represent the number the user enters. It's still not doing proper validation, but better than the original code. Thanks @Mark!

For money you might well want to use NSDecimalNumber rather than double so that you do not have rounding issues — mmmmmm, Sep 20 '12 at 23:52
@Mark Yeah, I agree, I'm actually going to edit the original code to do that. — Jason Coco, Sep 20 '12 at 23:58

With Swift 5, NumberFormatter has a property called currencySymbol. currencySymbol has the following declaration:

var currencySymbol: String! { get set }

The string used by the receiver as a local currency symbol.

Therefore, if required for your formatting style, you can set this property to an empty String.

The following Playground sample code shows how to set your currency formatting style with an empty symbol:

import Foundation

let amount = 12000

let formatter = NumberFormatter()
formatter.numberStyle = NumberFormatter.Style.currency
formatter.currencySymbol = ""
formatter.locale = Locale(identifier: "en_US") // set only if necessary

let result = formatter.string(for: amount)
print(String(describing: result)) // prints: Optional("12,000.00")

as for Swift Language

let mymoney = 12000

let formatter = NSNumberFormatter()
formatter.numberStyle = .CurrencyStyle
formatter.currencySymbol = ""
formatter.locale = NSLocale.currentLocale()

let resultString = formatter.stringFromNumber(mymoney)!

Displays 9,999.99 without the currency & not as Optional.

let myDouble = 9999.99
let currencyFormatter = NumberFormatter()
currencyFormatter.usesGroupingSeparator = true
currencyFormatter.numberStyle = .currency
currencyFormatter.currencySymbol = ""
// localize to your grouping and decimal separator
currencyFormatter.locale = Locale.current

// We'll force unwrap with the !, if you've got defined data you may need more error checking

let priceString = currencyFormatter.string(from: NSNumber(value: myDouble))!
print(priceString) // Displays 9,999.99 without the currency & not as Optional
