Comment ajouter un TextField à UIAlertView dans Swift

J'ai ce code, mais je ne sais pas comment afficher un champ de texte à l'intérieur de UIAlertView.

var altMessage = UIAlertController(title: "Warning", message: "This is Alert Message", preferredStyle: UIAlertControllerStyle.Alert)
altMessage.addAction(UIAlertAction(title: "Done", style: UIAlertActionStyle.Default, handler: nil))
self.presentViewController(altMessage, animated: true, completion: nil)

J'ai ce code pour textfield, comment puis-je le montrer dans UIAlerView 

var my:UITextField = UITextField(frame: CGRectMake(0, 0, 10, 10))

J'ai aussi essayé ce code:

var alert = UIAlertView()
alert.title = "Enter Input"
alert.addButtonWithTitle("Done")
alert.alertViewStyle = UIAlertViewStyle.PlainTextInput
alert.addButtonWithTitle("Cancel")
alert.show()

Lorsque je spécifie le texte plainText AlertStyle, il affiche un TextField avec un espace réservé par défaut, "Connexion". Je souhaite modifier cela. Je souhaite afficher un clavier à pavé décimal. Je souhaite également gérer la valeur que l'utilisateur entre dans le champ textField. Quelqu'un peut il m'aider avec ça?

Vous pouvez accéder au champ de texte avec:

let textField = alert.textFieldAtIndex(0)

Ensuite, pour changer le texte de l'espace réservé:

textField.placeholder = "Foo!"

Et le type de clavier:

textField.keyboardType = ...

Essayez ce code (avec Swift):

func configurationTextField(textField: UITextField!)
    {
        println("configurat hire the TextField")

        if let tField = textField {

            self.textField = textField!        //Save reference to the UITextField
            self.textField.text = "Hello world"
        }
    }


 func handleCancel(alertView: UIAlertAction!)
        {
           println("User click Cancel button") 
           println(self.textField.text)
        }

 var alert = UIAlertController(title: "Alert Title", message: "Alert Message", preferredStyle: UIAlertControllerStyle.Alert)

    alert.addTextFieldWithConfigurationHandler(configurationTextField)

    alert.addAction(UIAlertAction(title: "Close", style: UIAlertActionStyle.Cancel, handler:handleCancel))
    alert.addAction(UIAlertAction(title: "Ok", style: UIAlertActionStyle.Default, handler:{ (UIAlertAction)in
            println("User click Ok button")
            println(self.textField.text)
        }))
    self.presentViewController(alert, animated: true, completion: {
            println("completion block")
        })

DansObjective C 

 UIAlertView *alertView =  [[UIAlertView alloc]initWithTitle:@"Duplicate file" message:@"A file with the same name already exists." delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil, nil];
 alertView.alertViewStyle = UIAlertViewStylePlainTextInput;

 [[alertView textFieldAtIndex:0] setText:@"Filename"];
 [[alertView textFieldAtIndex:0] setPlaceholder:@"Enter Filename"];
 [alertView show];

DansSwift 2.3 

func doSomething(){
    var alert = UIAlertController(title: "Duplicate file", message: "A file with the same name already exists.", preferredStyle: UIAlertControllerStyle.Alert)

    alert.addTextFieldWithConfigurationHandler(configurationTextField)

    alert.addAction(UIAlertAction(title: "Ok", style: UIAlertActionStyle.Default, handler:{ (UIAlertAction)in
         print("User click Ok button")
         print(self.textField.text)
    }))

 self.presentViewController(alert, animated: true, completion: {
     print("completion block")
 })
}

 func configurationTextField(textField: UITextField!){
     textField.text = "Filename"
 }

DansSwift 3

func doSomething(){
    var alert = UIAlertController(title: "Duplicate file", message: "A file with the same name already exists.", preferredStyle: UIAlertControllerStyle.alert)

    alert.addTextField(configurationHandler: configurationTextField)

    alert.addAction(UIAlertAction(title: "Ok", style: UIAlertActionStyle.default, handler:{ (UIAlertAction)in
        print("User click Ok button")
        print(self.textField.text)
    }))

    self.present(alert, animated: true, completion: {
        print("completion block")
    })
}

func configurationTextField(textField: UITextField!){
    textField.text = "Filename"
}

            var inputTextField: UITextField?

            //Create the AlertController
            let actionSheetController: UIAlertController = UIAlertController(title: "Rename", message: "", preferredStyle: .Alert)

            //Create and add the Cancel action
            let cancelAction: UIAlertAction = UIAlertAction(title: "Cancel", style: .Cancel) { action -> Void in
        //Do some stuff
            }
            actionSheetController.addAction(cancelAction)
            //Create and an option action

        //Do some other stuff
            }
            actionSheetController.addAction(nextAction)
            //Add a text field
            actionSheetController.addTextFieldWithConfigurationHandler { textField -> Void in
        // you can use this text field
        inputTextField = textField
            }

            //Present the AlertController
            self.presentViewController(actionSheetController, animated: true, completion: nil)

Mise à jour pour Swift 3:

utilisé sous le code simple: 

    func showAlertWithTwoTextFields() {

        let alertController = UIAlertController(title: "Add Event", message: "Enter event and it's description", preferredStyle: .alert)

        let saveAction = UIAlertAction(title: "Save", style: .default, handler: {
            alert -> Void in

            let eventNameTextField = alertController.textFields![0] as UITextField
            let descriptionTextField = alertController.textFields![1] as UITextField

            print("firstName \(String(describing: eventNameTextField.text)), secondName \(String(describing: descriptionTextField.text))")

            if eventNameTextField.text != "" || descriptionTextField.text != ""{

            }else{
               // self.showAlertMessageToUser(title: "Alert", messageToUser: "Fields should not be empty, Please enter given info...")
// Show Alert Message to User As per you want
            }

        })

        let cancelAction = UIAlertAction(title: "Cancel", style: .default, handler: {
            (action : UIAlertAction!) -> Void in

        })

        alertController.addTextField { (textField : UITextField!) -> Void in
            textField.placeholder = "Enter event Name"
        }
        alertController.addTextField { (textField : UITextField!) -> Void in
            textField.placeholder = "Enter event description in short"
        }

        alertController.addAction(saveAction)
        alertController.addAction(cancelAction)

        self.present(alertController, animated: true, completion: nil)
    }

// Profitez du codage ...!

import UIKit

    // MARK: - UIAlertController+Present

    private struct ButtonsName {
        static let Ok = NSLocalizedString("uIAlertController.buttonName.ok", comment: "")
        static let Cancel = NSLocalizedString("uIAlertController.buttonName.cancel", comment: "")
    }


    class func suggestionAlertViewWithTitle(title:String?, placeholder:String, message:String, presenter:UIViewController, destructive:Bool = false,
                                            okButtonCompletion:((enteredSuggestion:String?)->Void)?, cancelButtonCompletion:(()->Void)?, presentCompletion:(()->Void)?) {
        var alertTitle = UIAlertController.appName()
        if let userTitle = title {
            alertTitle = userTitle
        }

        controller.addAction(okAction)

    }

    // MARK: - Private

    private static func appName () -> String {
        return NSBundle.mainBundle().infoDictionary!["CFBundleName"] as! String
    }
}

usage:

    UIAlertController.suggestionAlertViewWithTitle(nil, placeholder: placeholder, message: message,
                                                          presenter: self, destructive: false,
                                                          okButtonCompletion: { (enteredSuggestion) in
                self.logger.sendAllLogs(self.currentUser, suggestedTitle: enteredSuggestion)
        }, cancelButtonCompletion:nil, presentCompletion: nil)

un peu surchargé, mais vous pouvez toujours rendre certains paramètres optionnels ou/et par défaut

Swift 5

public func alertWithTextField(title: String? = nil, message: String? = nil, placeholder: String? = nil, completion: @escaping ((String) -> Void) = { _ in }) {
    let alert = UIAlertController(title: title, message: message, preferredStyle: .alert)
    alert.addTextField() { newTextField in
        newTextField.placeholder = placeholder
    }
    alert.addAction(UIAlertAction(title: "Cancel", style: .cancel) { _ in completion("") })
    alert.addAction(UIAlertAction(title: "Ok", style: .default) { action in
        if
            let textFields = alert.textFields,
            let tf = textFields.first,
            let result = tf.text
        { completion(result) } 
        else
        { completion("") }
    })
    navigationController?.present(alert, animated: true)
}

Usage:

alertWithTextField(title: "bork", message: "borkborkbork", placeholder: "bork?") { result in
    print(result)
}

Je vois que vous utilisez déjà la nouvelle variable UIAlertController - bonne idée, car l’ancienne API n’est guère utile si vous utilisez de toute façon Swift. Mais alert.textFieldAtIndex: ne fonctionnera pas pour cela; c'est pour UIAlertView seulement.

Heureusement, UIAlertController a une méthode pour ajouter des champs de texte .
