Answer 1

You cannot modify the frame or the look of the keyboard, since it works kind of like an overlay over your app and it's not a direct subview in the window where your app lives.

You can create a custom keyboard for this approach, but remember to follow the iOS Human Interface Guidelines.

You can also create a custom view that provides input (for e.g. a bunch UIButtons that append a letter to a UITextView if you press them).
