我希望格式化程序显示 - 4.00英镑为 - 4.00英镑,但它一直显示为(4.00英镑),为什么?NSNumberFormatter负值显示括号
下面的函数将字符串“00000014”变成“£00.14”,它也应该变成负值。但数字格式化程序似乎添加了括号。
代码如下:
+(NSString *)pfsCurrencyAmountString:(NSString *)amount CurrencyCodeAsString:(NSString *)code{
if (amount == nil) {
return nil;
}
int amountLength = [amount length];
NSMutableString *amountMutable = [NSMutableString stringWithString:amount];
if (amountLength > 2) {
[amountMutable insertString:@"." atIndex:amountLength - 2];
}
NSLocale *locale = [[NSLocale alloc] initWithLocaleIdentifier:@"en_US"];
NSNumberFormatter *currencyStyle = [[NSNumberFormatter alloc] init];
[currencyStyle setFormatterBehavior:NSNumberFormatterBehavior10_4];
[currencyStyle setNumberStyle:@"NSNumberFormatterCurrencyStyle"];
[currencyStyle setLocale:locale];
[currencyStyle setCurrencyCode:code];
NSNumber * balance = [currencyStyle numberFromString:amountMutable];
[currencyStyle setNumberStyle:NSNumberFormatterCurrencyStyle];
return [currencyStyle stringFromNumber:balance];
}
'NSNumberFormatterCurrencyStyle'货币值可以是负数:O ??? –
请在寻求新的答案之前寻找现有的答案。 –
顺便说一句,'[currencyStyle setNumberStyle:@“NSNumberFormatterCurrencyStyle”];'行是不正确的;使用'[currencyStyle setNumberStyle:NSNumberFormatterCurrencyStyle];'就像你以后做的那样。 – Rob
