iphone - 在格式化价格时获取 NSNumberFormatter 以拼出货币

Question

我现在正在我的应用中实现应用内购买。 为了获得本地化价格，我执行以下操作:

NSNumberFormatter *numberFormatter = [[NSNumberFormatter alloc] init];
  [numberFormatter setFormatterBehavior:NSNumberFormatterBehavior10_4];
  [numberFormatter setNumberStyle:NSNumberFormatterCurrencyStyle];
  [numberFormatter setLocale:self.priceLocale];
  NSString *formattedString = [numberFormatter stringFromNumber:self.price];
  [numberFormatter release];
  return formattedString;

这很好用。但是我想得到一个可以转换为 ASCII 字符串的字符串。那么有没有办法让数字格式化程序拼出货币。例如“0.99€”将变成“0.99 Eur”或“0.99 Euro”。

Answer 1

有一种方法可以通过在格式化程序的格式中替换 ¤ 来做到这一点:

NSNumberFormatter *numberFormatter = [[NSNumberFormatter alloc] init];
[numberFormatter setFormatterBehavior:NSNumberFormatterBehavior10_4];
[numberFormatter setNumberStyle:NSNumberFormatterCurrencyStyle];
[numberFormatter setLocale:self.priceLocale];
NSString *currencyString = [numberFormatter internationalCurrencySymbol];
NSString *posFormat = [numberFormatter positiveFormat];
formatterFormat = [formatterFormat stringByReplacingOccurrencesOfString:@"¤" withString:currencyString];
[numberFormatter setPositiveFormat:posFormat];
NSString *formattedString = [numberFormatter stringFromNumber:self.price];
[numberFormatter release];
return formattedString;
