Answer 1

AlertViewController

        // use UIAlertController
        UIAlertController *alert= [UIAlertController
                                      alertControllerWithTitle:@"Title"
                                      message:@"SubTitle"
                                      preferredStyle:UIAlertControllerStyleAlert];

        UIAlertAction* ok = [UIAlertAction actionWithTitle:@"OK" style:UIAlertActionStyleDefault
                                                   handler:^(UIAlertAction * action){
                                                       //Do Some action here
                                                       UITextField *textField = alert.textFields[0];
                                                       NSLog(@"text was %@", textField.text);

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

                                                           NSLog(@"cancel btn");

                                                           [alert dismissViewControllerAnimated:YES completion:nil];

                                                       }];

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

        [alert addTextFieldWithConfigurationHandler:^(UITextField *textField) {
            textField.placeholder = @"placeHolderText";
            textField.keyboardType = UIKeyboardTypeDefault;
        }];

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

UIAlertView

        UIAlertView* dialog = [[UIAlertView alloc] initWithTitle:@"Title"
                                                         message:@"SubTitle"
                                                        delegate:self
                                               cancelButtonTitle:@"Cancel"
                                               otherButtonTitles:@"OK", nil];

        dialog.alertViewStyle = UIAlertViewStylePlainTextInput;

        [dialog show];

    }

Answer 2

  func askForName() {
let alert = UIAlertController(title: "Enter Text",
                              message: "Enter some text below",
                              preferredStyle: .alert)

alert.addTextField { (textField) in
  textField.text = "New Text"
}

let action = UIAlertAction(title: "OK", style: .default, handler: { [weak alert] (_) in
  let textField = alert!.textFields![0]
  print("Text field: \(textField.text)")
})

alert.addAction(action)

present(alert, animated: true, completion: nil)

}

        UITextField * namefield = textfields[0];
        UITextField * passwordfiled = textfields[1];
        NSLog(@"%@:%@",namefield.text,passwordfiled.text);
