Custom keyboard size

Hello,


I'm working on iPad application that requires to enter some specific data into some text fields (predefined values like "1/2", "1/4", "1/8", "1/16" etc). To make it user-friendly, I'm using a custom keyboard for such fields (using inputView property).

There is a problem with a sliding keyboard feature. If you type any normal text field (without custom keyboard) a standard keyboard will be shown. Then you can change it to the small (sliding) keyboard. But then if you select text field with a custom keyboad the system will show custom keyboard's view in the same small container.

Is there any way to either stretch custom keyboard to the full size or disable sliding keyboard in the app?


Thanks,
Anton
