Answer 1

您可以使用NSNumberFormatterCurrencyStyle获得所需的结果。

NSNumberFormatter *indCurrencyFormatter = [[NSNumberFormatter alloc] init];
[indCurrencyFormatter setNumberStyle:NSNumberFormatterCurrencyStyle];
[indCurrencyFormatter setLocale:[[NSLocale alloc] initWithLocaleIdentifier:@"en_IN"]];
NSString *formattedString =  [indCurrencyFormatter stringFromNumber:[NSNumber numberWithFloat:120000]];

Answer 2

使用NSNumberFormatter

示例：

NSNumberFormatter *numberFormatter = [NSNumberFormatter new];
[numberFormatter setNumberStyle:NSNumberFormatterDecimalStyle]; // Here you can choose the style

NSString *formatted = [numberFormatter stringFromNumber:[NSNumber numberWithInteger: 120000]];

或者您可以使用：  [[NSLocale currentLocale] objectForKey:NSLocaleGroupingSeparator]

<强>更新

在印度货币格式中，您必须将@"en_IN"设置为numberFormatter Locale，只需添加以下行：

  [numberFormatter setLocale:[[NSLocale alloc] initWithLocaleIdentifier:@"en_IN"]]; 

Answer 3

NSDecimalNumber *price = [NSDecimalNumber decimalNumberWithString:@"120000"];
NSLocale *priceLocale = [[NSLocale alloc] initWithLocaleIdentifier:@"en-in"]; 

NSNumberFormatter *currencyFormatter = [[NSNumberFormatter alloc] init];
[currencyFormatter setNumberStyle:NSNumberFormatterCurrencyStyle];
[currencyFormatter setLocale:priceLocale];
NSString *format = [currencyFormatter positiveFormat];
[currencyFormatter setPositiveFormat:format];

NSString *currencyString1 = [currencyFormatter stringFromNumber:price];
DLog(@"%@",currencyString1);
