ValidatorControlDelegate is only possible when using `ValidatorTextField`

[markst]

I use https://github.com/CosmicMind/Material
Which has it's own styled UITextField subclasses.

My subclassed text field implements ValidatorControl protocol.

class ValidationTextField: ErrorTextField, ValidatorControl

It would be good if I could use ValidatorControlDelegate when using other classes besides the provided ValidatorTextField.

The ValidatorControlDelegate does not require the use of ValidatorTextField, only a class that conforms to the ValidatorControl protocol. Your custom ValidationTextField does this. Are you having difficulty building an implementation using the ValidatorControlDelegate that uses your ValidationTextField?

Reference:

• ValidatorControlDelegate

@aamctustwo thanks for response, I'm not sure I'm convinced.

The logic for ValidatorControlDelegate.validatorControlDidChange is seems to be within the UITextField subclass ValidatorTextField - which relies on subscribing to UITextFieldTextDidChange notification:
https://github.com/ustwo/formvalidator-swift/blob/master/Sources/Controls/ValidatorTextField-UIKit.swift#L73

You should be able to do something similar with your ValidationTextField. Since ErrorTextField is just a descendant subclass of UITextField ultimately. You may be able to tie into some of CosmicMind Material's other delegates for TextField, but you'd have to investigate that library further.

• ErrorTextField: https://github.com/CosmicMind/Material/blob/5e81df5a0c3448b9c811d82e57be02e57abd59f5/Sources/iOS/ErrorTextField.swift#L33
• TextField: https://github.com/CosmicMind/Material/blob/5e81df5a0c3448b9c811d82e57be02e57abd59f5/Sources/iOS/TextField.swift#L66

Exactly. In which case how would you feel about exposing ValidatorTextFieldResponder to make this possible without having to duplicate a lot of logic?

@aamctustwo

As it is originally written, the ValidatorTextFieldResponder and its corresponding implementations for text views and for AppKit were tightly coupled to the core UI component (ValidatorTextField) and never intended to be publicly exposed.

If you'd like to raise a PR with an implementation, I'd be happy to take a look at it.
