How to add UITextField?

[usinuniverse]

How do I add a UITextField?
It is not shown in the example, is there any such function?

[keisukeYamagishi]

Good issues 👍
Currently there is no such function, so
I want to add this function
Do you have a good way?

How about this?
(If it does n’t affect existing interfaces...)

// MARK: - UIAlertController
extension UIAlertController {    
    public func addTextInputAction(actions: [AlertAction], textFieldConfiguration: ((UITextField) -> Void)?) -> Observable<(Int, String?)> {
        return Observable.create { [weak self] observer in
            guard let self = self else { return Disposables.create() }
            var textField: UITextField?
            self.addTextField(configurationHandler: {
                textField = $0
                textFieldConfiguration?($0)
            })
            actions.map { action in
                return UIAlertAction(title: action.title, style: action.style, handler: { _ in
                    observer.onNext((action.type, textField?.text))
                    observer.onCompleted()
                })
            }.forEach(self.addAction)
            return Disposables.create { self.dismiss(animated: true) }
        }
    }
}

// MARK: - UIViewController
extension UIViewController {
    public func textInputAlert(title: String?,
                      message: String? = nil,
                      actions: [AlertAction] = [AlertAction(title: "OK")],
                      vc: UIViewController? = nil,
                      textFieldConfiguration: ((UITextField) -> Void)? = nil) -> Observable<(Int, String?)> {
        let parentVc = vc ?? self
        let alertController = UIAlertController(title: title, message: message, preferredStyle: .alert)
        return
            alertController
                .addTextInputAction(actions: actions, textFieldConfiguration: textFieldConfiguration)
                .do(onSubscribed: {
                    parentVc.present(alertController, animated: true)
                })
    }
}

In this way a single TextField can be supported.

Good vibes 👍
but, I think need slightly extended interface
so I think want to same interface
And I think it's better to support multiple UITextFields instead of a single UITextField.

Thank you!

That's true.

I feel it difficult to provide TextField in the library.
Sorry. Good ideas don't come up...
