It is currently not possible to prevent keyboard splitting. The most you can hope for is to either
- Provide user feedback after the user splits the keyboard
notifying them that this is not the best user experience and is not
supported by your app.
- Roll your own keyboard
IMO, #1 is the best approach. Rolling your own keyboard -- with localization support -- is almost never practical.
