How can i check if a field contains valid data?

I have a continue button that should only be enabled if all fields are valid, how to check that?

Hi Radu! You can use datasource methods to use your own regular expressions for typing and to check field when view did end editing. func animatedFieldTypingMatches(_ animatedField: AnimatedField) -> String? use it to send your custom regular expression to check if a character is allowed or not. For example “[A-Z0-9]”, with this you can only type uppercased letters and numbers func animatedFieldValidationMatches(_ animatedField: AnimatedField) -> String? use it to check field when did end editing with your own regular expression Also you can use delegate methods to get AnimatedField text when user ends editing func animatedFieldDidEndEditing(_ animatedField: AnimatedField) you can check and enable continue button in this method if animatedField.text is correct NOTE: In the future, I will add some kind of delegate method or parameter with the result of this check. Thank you for using AnimatedField!

hey Alberto, thanks for the quick answer!

i am interested to do something like this, using default regex rules from your code

on login button action:

if usernameField.isValid && passwordField.isValid {
continue
}

i currently cant do that with delegates. isValid is some kind of function that validates that current field on demand

thanks!

Good idea! I will update AnimatedField with isValid parameter

Hi Radu! I've updated and released new version 2.0.3 with isValid parameter and new delegate method: didShowAlertMessage. Example is also updated ;)
