Decimal local separator

[Romaric5M]

Hi,

As french people, I use a comma instead of point as decimal separator ...
When I use a XLFormRowDescriptorTypeDecimal row, it displays a decimal keyboard with comma which is great for amount fields.

But as I noticed the -[NSString doubleValue] isn't respecting the locale decimal separator; it expects a point, not a comma.
So finally my value isn't correct.

Is there a trick to parse correctly my amount value ?

Thanks a lot.

I find a solution by replacing

self.rowDescriptor.value =  @([self.textField.text doubleValue]);

with the following lines

NSNumberFormatter * myNumFormatter = [[NSNumberFormatter alloc] init];
[myNumFormatter setLocale:[NSLocale currentLocale]];
[myNumFormatter setNumberStyle:NSNumberFormatterDecimalStyle];
self.rowDescriptor.value =  [myNumFormatter numberFromString:self.textField.text];

It's not the perfect solution but it finally get the correct double value.
Hope it will be helpful for next bugfix :)

Same problem for me. The bug fix is simple but need to be merged in pod so everyone can use it without forking the project.

NSFormatter support was merged.

This is not solved. Other separators than '.' are not respected.
The line now reads:

self.rowDescriptor.value =  [NSDecimalNumber decimalNumberWithString: self.textField.text];

To respect the current locale it should read (according to this):

self.rowDescriptor.value =  [NSDecimalNumber decimalNumberWithString:self.textField.text locale:NSLocale.currentLocale];

I will create a pull request... no. 31 as of now :|

This fix does not help fully. If I have set value to, e.g., "12,34" it is converting to "12.34" after I get out of this field. Using NSNumberFormatter helps to avoid this transformation, however It can't help me with changing this value to dot-format after I select this field again. With useValueFormatterDuringInput flag I am not able to insert new commas while editing, so the only way is create a custom formatter for this case.
Is it a good idea to implement a default NSNumberFormatter inside decimal row?

The smoothest solution is to use 2 number formatters - one in form row and one as extension for NSNumber, which helps to call displayText method with formatted value, avoiding glitches of NSNumberFormatter with useValueFormatterDuringInput flag

quantityRow.valueFormatter = decimalFormatter

extension NSNumber {
    public override func displayText() -> String! {
        let formatter = NSNumberFormatter()
        formatter.decimalSeparator = ","
        formatter.locale = NSLocale.currentLocale()
        formatter.numberStyle = .DecimalStyle
        return formatter.stringFromNumber(self)
    }
}
