如何制作自定义键盘？

Question

What are the rules I need to follow, when creating a custom keyboard for a UITextView?

1. Is it OK to use a subclass of UIView?
2. Do I need to implement a specific protocol?
3. Should it contain a variable with a specific type and name?
4. Anything else?

At this point I have already made my own keyboard with the buttons; and it shows up when the UITextView object becomes the FirstResponder as expected. But I cannot use it and I would like to know if there is a "proper way" or if I just have to find my own way to make things work.

Thanks in advance.
