How to add a TextField to UIAlertView in Swift

You can access the textfield with:

let textField = alert.textFieldAtIndex(0)

Then to change the placeholder text:

textField.placeholder = "Foo!"

And the keyboard type:

textField.keyboardType = ...

Try This Code (with 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")        })

In Objective 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];

In Swift 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" }

In Swift 3
