iphone - 在 iPhone SDK 中使用货币代码显示货币符号

Question

实际上，我想显示所有货币代码的货币符号，并且我使用这样的代码，但我只得到“$”符号

-(void) showCurrenciesList
{
    NSNumberFormatter *numFormatter = [[NSNumberFormatter alloc] init];                         
    [numFormatter setNumberStyle:NSNumberFormatterCurrencyStyle];
    //[numFormatter setLocale: [NSLocale currentLocale]];

    NSMutableArray *aryAllCurrencies = [[NSMutableArray alloc] init]; 
    //NSLocale *locale = [[[NSLocale alloc] initWithLocaleIdentifier: @"en_US"] autorelease];

    NSArray *currencyArray = [NSLocale ISOCurrencyCodes]; 
    NSLog(@"Currency array : %@",currencyArray);

    for (NSString *currencyCode in currencyArray) 
    {
        NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
        [numFormatter setCurrencyCode:currencyCode];
        NSString *currencySymbol = [numFormatter currencySymbol];
        [aryAllCurrencies addObject:currencySymbol];
        [pool release];     
    }   
    //[countriesArray sortUsingSelector:@selector(compare:)];
    NSLog(@"currencies array : %@",aryAllCurrencies);   
}

这是正确的还是有其他方法可以做到这一点？

这是一个直接的高成本解决方案

+(NSString *)getCurrencySybolByCurrecyCode:(NSString *)code
{
    NSArray *locales = [NSLocale availableLocaleIdentifiers];
    for (NSString *currentLocale in locales)
    {
        NSLocale *currentLoc = [[[NSLocale alloc] initWithLocaleIdentifier:currentLocale] autorelease];
        if([[currentLoc objectForKey:NSLocaleCurrencyCode] isEqualToString:code])
        {
            NSLog(@"find symbol for code = %@ %@", [currentLoc objectForKey:NSLocaleCurrencyCode], [currentLoc objectForKey:NSLocaleCurrencySymbol]);
            return [currentLoc objectForKey:NSLocaleCurrencySymbol];        }
    }
    return nil;
}
