What is NxEnabled?

It’s a fairly common case, when the enabled state of button depends on some textable elements such as TextView, TextField. So this library allows the simplest way to achive this purpose with only few lines of code.

Getting started

Typical login screen with short, beautiful validation code:


                                              
                                                loginButton.isEnabled(by: usernameTextField, passwordTextField) { username, password in

username.characters.count > 5 && password.characters.count > 5

}

you can also combine together UITextView with UITextField‘s:


                                              
                                                signUpButton.isEnabled(by: firstnameTextField, lastnameTextField, bioTextView) { firstname, lastname, bio in

return /* validation value */

}

So there is also oportunity to add not UI element:

Implement Textable protocol
Be a successor from NSObject
Not forget about dynamic label for property
Done.


                                              
                                                class Object: NSObject, Textable {

dynamic var value: String?

var textKey: String {

return “value”

}

}

NOTE:

One important case is that you should clear button’s bag. It removes all observers from textable elements. Usually it needs to do in deinit method.


                                              
                                                deinit {

signUpButton.clearBag()

}

Now library allows to add textable elements up to six.
