comma separated thousand NSString stringWithFormat

Question

Is it possible to display 1000.99 as 1,000.99 using

[NSString stringWithFormat:@"£%0.2f", 1000.99]

Please guide me if I am not on the right track to achieve this?

Solution 1

See NSNumberFormatter.

It can handle all your numeric formatting needs and do so in an automatically localized fashion, when used correctly (since currencies around the world are often written with different punctuation & formatting).

In particular, check out the number formatting guide linked to at the top of the class documentation

Solution 2

Using NSNumberFormatter:

NSNumberFormatter *numberFormatter = [[[NSNumberFormatter alloc] init] autorelease];
[numberFormatter setNumberStyle: NSNumberFormatterCurrencyStyle];
NSString *numberAsString = [numberFormatter stringFromNumber:[NSNumber numberWithFloat: 1000.99]];
NSLog(@"%@", numberAsString);

+1 NSNumberFormatter is definitely the correct way to do this.
