You can create a custom input view with needed appearance.
To achieve this, you can use property inputView if UITextField:

The custom input view to display when the text field becomes the first responder.

Here you can find a guide about custom input views.
Also I've created small example with custom input view without buttons: https://github.com/K-Be/KeyboardNotifications/tree/master_CustomInput .
