Hi, how we can change BKCurrencyTextField formats, for ex: 44.333 like this one, or enable only integer types: 44,000 ?

Is there any way to know when the card pattern was been completer to ask for MM//YY?

Hi guys, congratulation so far!

Validation Methods:
I just wanted to tell you to if you can add a method which return a boolean if the credit card number, expiration date and cvv is in a valid format. I created it subclassing your class but would be better if you can add it directly in your code ;) Here the code:

    func isValidCCNumber() -> Bool {

        let ccNumberRegex = "^(([0-9]{4})[-|\\s| ]([0-9]{4})[-|\\s| ]([0-9]{4})[-|\\s| ]([0-9]{4}))|(([0-9]{4})[-|\\s| ]([0-9]{6})[-|\\s| ]([0-9]{5}))"
        let ccNumberPredicate = NSPredicate(format:"SELF MATCHES %@", ccNumberRegex)
        return ccNumberPredicate.evaluateWithObject(self.text!)
    }

    func isValidCCEpirationDate() -> Bool {

        let ccExpirationDateRegex = "(?:0[1-9]|1[0-2])\\/2[0-9]{3}"
        let ccExpirationDatePredicate = NSPredicate(format:"SELF MATCHES %@", ccExpirationDateRegex)
        return ccExpirationDatePredicate.evaluateWithObject(self.text!)
    }

    func isValidCCCvv() -> Bool {

        let ccCvvRegex = "^([0-9]{3,4})$"
        let ccCvvPredicate = NSPredicate(format:"SELF MATCHES %@", ccCvvRegex)
        return ccCvvPredicate.evaluateWithObject(self.text!)
    }

Expiration Date Year Length:
In my app I need to use 4 digit number in the textfield but actually your code allow just 2. Would be better if you can let the user decide the length.

Separator Style:
In your app you automatically add the separation in the credit card number, which is an whitespace, and in the cvv, which is an " / ". Would be better if you can let the user decide them.

Hope you'll include them ;)

Mastercard is releasing new cards that use BINs ranging from 222100-272099. Currently, this does not work with the current card patterns.

Hello,
can you please submit a new cocoapods release?

Thanks,

iOS 6.0 not support

BKCurrencyTextField

If i set the card number programatically it doesn't update the card logo. It only updates when you set the card number via writing it directly from keyboard.

The following case does NOT work:

self.cardNumberField.text = numberOfCard

It updates the text in the field but it does NOT update the card logo, how can I do to make the card logo load in this case where I set the card number programatically ?

I added BKMokeyKit with help cocoapods. And when I try compile my project I have error:

BKMoneyKit/BKForwardingTextField.m:15:1: Cannot synthesize weak property because the current deployment target does not support weak references

If I change Deployment Target in BKMoneyKit my project will compile.

Cocoapods version is 1.1.0

BKCurrencyTextField crashes with a bluetooth keyboard connected if the user types a letter.

Can you add a podspec so this class can be used with CocoaPods?

BKCurrencyTextField does not respect the horizontal text alignment set via storyboard

I'm trying to format the credit card number without setting the textfield class with BKCardNumberField. So I have typed this

   let bkcardNumberFormatter = BKCardNumberFormatter()

  func textField(textField: UITextField, shouldChangeCharactersInRange range: NSRange, replacementString string: String) -> Bool {

    textField.text = bkcardNumberFormatter.formattedStringFromRawString(newString)
    return true
}

it is formatting but it is adding one more character in the end and can't delete text after whitespace. So please could you help me with it?

Hi, thanks for sharing this great library.
I have problem with maximum fraction digits, when this number is equal to 3.
for ex in BKCurrencyTextField.m file:

_numberFormatter = [[NSNumberFormatter alloc] init];
_numberFormatter.numberStyle = NSNumberFormatterCurrencyStyle;

    
    [_numberFormatter setMaximumFractionDigits:3];
    [_numberFormatter setCurrencyCode:@"KGS"];
    [_numberFormatter setCurrencySymbol:@""];
    [_numberFormatter setLocale:[NSLocale localeWithLocaleIdentifier:@"ru_RU"]];
    
    
    _nonNumericRegularExpression = [BKMoneyUtils nonNumericRegularExpression];
    _numberCharacterSet = [BKMoneyUtils numberCharacterSet];
    
    self.placeholder = [_numberFormatter stringFromNumber:@(0)];

in this case if press any number, for ex 9, then press 0(zero) nothing changes.
Another words when setMaximumFractionDigits:2 everything is ok, but when 3 there is a problem.

Please check this situation since this returns invalid dates.
Expiration dates in credit card is in gregorian calendar.

To replicate just change the calendar in the settings to Japanese for example.

The code is breaking when you pop or dismiss the view controller which has bkmoneykit textfields. Can you please fix this asap?

Tapping numbers too quickly in BKNumberField breaks formatting and is not recoverable unless the view is reloaded. I believe it's due to cardPatternInfo not being properly instantiated fast enough. We end up with BKCardNumberFormatter.cardPatternInfoWithNumberString returning nil and setting self.cachedPrefix and self.cardPatternInfo to nil. This then never recovers. I can try to find a solution, but don't have time at the moment. Just wanted to point it out for now.

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:

I really miss UITextFieldTextDidChangeNotification. :)

Since shouldChangeCharacters always returns NO, it would be great to add a manual notification.

[[NSNotificationCenter defaultCenter] postNotificationName:UITextFieldTextDidChangeNotification object:self];
