Question

我想将此字符串：1000000转换为以下格式：10,00,000但是，我得到如下输出：1,000,000这是错误的。我需要10,00,000。

我的代码：

NSString *newString = [textField.text stringByReplacingCharactersInRange:range withString:string];
         inputnumber = newString;
NSNumberFormatter* formatter = [[NSNumberFormatter alloc] init];
[formatter setNumberStyle:NSNumberFormatterCurrencyStyle];
[formatter setCurrencySymbol:@""];
[formatter setMaximumFractionDigits:2];
[formatter setMinimumFractionDigits:2];
[formatter setUsesGroupingSeparator:YES];
[formatter setCurrencyGroupingSeparator:@","];
// [formatter setCurrencyDecimalSeparator:@"."];
[formatter setGroupingSeparator:@","];
NSNumber *num = [NSNumber numberWithDouble:[inputnumber doubleValue]];
inputnumber = [formatter stringFromNumber:num];

Answer 1

这是印度货币格式。因此，您必须将@"en_IN"设置为currencyFormatter Locale。

工作代码：

NSNumberFormatter *currencyFormatter = [[NSNumberFormatter alloc] init];
[currencyFormatter setNumberStyle:NSNumberFormatterCurrencyStyle];
[currencyFormatter setCurrencySymbol:@""];
[currencyFormatter setLocale:[[[NSLocale alloc] initWithLocaleIdentifier:@"en_IN"] autorelease]];
NSLog(@"Final Value :: %@", [currencyFormatter stringFromNumber:[NSNumber numberWithFloat:1000000]]);

Answer 2

对于Swift，请查看：

 let initalValue:NSString = "1000000"
    let currencyFormatter = NSNumberFormatter()
    currencyFormatter.numberStyle = NSNumberFormatterStyle.CurrencyStyle
    currencyFormatter.locale = NSLocale (localeIdentifier: "en_IN")
    let formattedValue = currencyFormatter.stringFromNumber(initalValue.doubleValue)
    print(formattedValue)
