问题描述

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];


 }

如何将SumCurrency.text设置为1,999而不是1999

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