Blank field user types character crash

[dulbrich]

If you have a blank BKCurrencyTextField and you try and type or paste a letter character rather than a number character it crashes the app.

Here's the error:

Hi, I found the same issue, I create a fix in BKCurrencyTextField.m in line 67, Its a workaround, but solve my problem.

if (self.numberFormatter.maximumFractionDigits > 0) {

    if ([decimalNumber isEqualToNumber:[NSDecimalNumber notANumber]]) {

        decimalNumber = 0;

    }else{

        decimalNumber = [decimalNumber decimalNumberByDividingBy:[NSDecimalNumber decimalNumberWithMantissa:1 exponent:self.numberFormatter.maximumFractionDigits isNegative:NO]];

    }
}
