Using NSNumberFormatter to format currency in output UILabel

NSNumberFormatter * fmt;
NSNumber          * n;

fmt = [ [ NSNumberFormatter alloc ] init ];
n   = [ NSNumber numberWithFloat: 10 ];

[ fmt setFormatterBehavior: NSNumberFormatterBehavior10_4 ];
[ fmt setCurrencySymbol: @"$" ];
[ fmt setNumberStyle: NSNumberFormatterCurrencyStyle ];

 // NSLog( @"%@", [ fmt stringFromNumber: n ];

[ fmt release ]


-(IBAction)buttonPressed1:(id)sender
 {
double currency = [Amount1.text doubleValue] + [Amount2.text doubleValue]; 

SumCurrency.text = [NSString stringWithFormat:@"%0.0f", currency];


 }

How do I get the SumCurrency.text formated as 1,999 instead of 1999

Please help .. I am new to Objective - C , but my project is almost 95 % on interface builder .

I just need help with above code to implement .. Please I am struggling a lot with this .

Regards , Newbie.

-(IBAction)buttonPressed1:(id)sender
{
    double currency = [Amount1.text doubleValue] + [Amount2.text doubleValue]; 
    NSNumberFormatter *numberFormatter = [[[NSNumberFormatter alloc] init] autorelease];
    [numberFormatter setNumberStyle: NSNumberFormatterCurrencyStyle];
    NSString *numberAsString = [numberFormatter stringFromNumber:[NSNumber numberWithInt:currency]];
    SumCurrency.text = [NSString stringWithFormat:@"Converted:%@",numberAsString];

[ fmt release ];

use 

SumCurrency.text = [ fmt stringFromNumber: n ];

and you are done with it

Note to person who asked and answered this question.

You said,

[numberFormatter stringFromNumber:[NSNumber numberWithInt:currency]];

but I think if your using an object of a class, like NSNumber, then you might want to put

[numberFormatter stringFromNumber:(NSNumber *) currency]];

See what I'm trying to say?
