NSNumberFormatter用于不同区域

Question

I will receive $5.00 for US, ¥5.00 for Japan, 5.00€ for Europe, etc. But I don't want that. I want to get the same thing in every locale: $5.00 for US, $5.00 for Japan, $5.00 for Europe. Here is what I have tried:

NSNumberFormatter *numberFormatter = [[NSNumberFormatter alloc] init];
[numberFormatter setNumberStyle: NSNumberFormatterCurrencyStyle];
NSNumber *tmp = (NSNumber *)[NSString notNullString:[details objectForKey:@"askingPricePerCarat"]];
NSString *numberAsString = [numberFormatter stringFromNumber:[NSNumber numberWithDouble:[tmp doubleValue]]];
askingPricePerCarat = numberAsString;

Answer 1

Finally i got the answer of this question, is based on the device's Region Format settings, not the language. If the region is set to United States you will get en_US regardless of which language you're using

 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 ];

use

Currency.text = [ fmt stringFromNumber: n ];
