Here's handy method with submit/cancel and completion handler for text if inputted:

/**
 Presents an alert controller with a single text field for user input

 - parameters:
    - title: Alert title
    - message: Alert message
    - placeholder: Placeholder for textfield
    - completion: Returned user input
 */

func showSubmitTextFieldAlert(title: String,
                              message: String,
                              placeholder: String,
                              completion: @escaping (_ userInput: String?) -> Void) {

    let alertController = UIAlertController(title: title,
                                            message: message,
                                            preferredStyle: .alert)

    alertController.addTextField { (textField) in
        textField.placeholder = placeholder
        textField.clearButtonMode = .whileEditing
    }

    let submitAction = UIAlertAction(title: "Submit", style: .default) { (action) in
        let userInput = alertController.textFields?.first?.text
        completion(userInput)
    }

    let cancelAction = UIAlertAction(title: "Cancel", style: .cancel) { (_) in
        completion(nil)
    }

    alertController.addAction(submitAction)
    alertController.addAction(cancelAction)

    present(alertController, animated: true)
}

Example of implementation with Swift 3:

var textField: UITextField?

// create alertController
let alertController = UIAlertController(title: "Title", message: "Message", preferredStyle: .alert)
  alertController.addTextField { (pTextField) in
  pTextField.placeholder = "usefull placeholdr"
  pTextField.clearButtonMode = .whileEditing
  pTextField.borderStyle = .none
  textField = pTextField
}

// create cancel button
alertController.addAction(UIAlertAction(title: "Cancel", style: .cancel, handler: { (pAction) in
  alertController.dismiss(animated: true, completion: nil)
}))

// create Ok button
alertController.addAction(UIAlertAction(title: "OK", style: .default, handler: { (pAction) in
  // when user taps OK, you get your value here
  let inputValue = textField?.text
  alertController.dismiss(animated: true, completion: nil)
}))

// show alert controller
self.present(alertController, animated: true, completion: nil)

UIAlertView *av = [[UIAlertView alloc]initWithTitle:@"Title" message:@"Please enter someth" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"OK", nil];

av.alertViewStyle = UIAlertViewStylePlainTextInput;

[av textFieldAtIndex:0].delegate = self;
[av show];

also, you will need to implement UITextFieldDelegate, UIAlertViewDelegate protocols.

and if you user uialertcontroller then use this one

UIAlertController * alert=   [UIAlertController
                              alertControllerWithTitle:@"My Title"
                              message:@"Enter User Credentials"
                              preferredStyle:UIAlertControllerStyleAlert];

UIAlertAction* ok = [UIAlertAction actionWithTitle:@"OK" style:UIAlertActionStyleDefault
                                           handler:^(UIAlertAction * action) {
                                               //Do Some action here

                                           }];
UIAlertAction* cancel = [UIAlertAction actionWithTitle:@"Cancel" style:UIAlertActionStyleDefault
                                               handler:^(UIAlertAction * action) {
                                                   [alert dismissViewControllerAnimated:YES completion:nil];
                                               }];

[alert addAction:ok];
[alert addAction:cancel];

[alert addTextFieldWithConfigurationHandler:^(UITextField *textField) {
    textField.placeholder = @"Username";
}];
[alert addTextFieldWithConfigurationHandler:^(UITextField *textField) {
    textField.placeholder = @"Password";
    textField.secureTextEntry = YES;
}];

[self presentViewController:alert animated:YES completion:nil];

Answer 5

UIAlertViewController with text input

UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"Title"
                                                               message:nil
                                                        preferredStyle:UIAlertControllerStyleAlert];
[alert addTextFieldWithConfigurationHandler:^(UITextField *textField) {
    // optionally configure the text field
    textField.keyboardType = UIKeyboardTypeAlphabet;
}];

UIAlertAction *okAction = [UIAlertAction actionWithTitle:@"OK"
                                                   style:UIAlertActionStyleDefault
                                                 handler:^(UIAlertAction *action) {
                                                     UITextField *textField = [alert.textFields firstObject];
                                                     textField.placeholder = @"Enter Input";
                                                 }];
[alert addAction:okAction];

[self presentViewController:alert animated:YES completion:nil];

Answer 6

This one is work for me:

let passwordString = lableGetPassword.text
    var textField: UITextField?
    
    // create alertController
    let alertController = UIAlertController(title: "Password", message: "Save the password. Give a tag name.", preferredStyle: .alert)
    alertController.addTextField { (pTextField) in
        pTextField.placeholder = "Tag Name"
        pTextField.clearButtonMode = .whileEditing
        pTextField.borderStyle = .none
        textField = pTextField
    }
    
    // create cancel button
    alertController.addAction(UIAlertAction(title: "Cancel", style: .cancel, handler: { (pAction) in
        alertController.dismiss(animated: true, completion: nil)
    }))
    
    // create Ok button
    alertController.addAction(UIAlertAction(title: "Save", style: .default, handler: { [self] (pAction) in
        // when user taps OK, you get your value here
        let name = textField?.text
        save(name: name!, password: passwordString!)
        alertController.dismiss(animated: true, completion: nil)
    }))
    
    // show alert controller
    self.present(alertController, animated: true, completion: nil)
