Answer 1

Is this possible that i can use iPhone keyboard and edit or add extra-function or any other API given to extend keyboard functionality?

You can extend it by adding additional view on the upper side of it, like a toolbar with additional buttons, that will not be inside the keyboard but only over it

Should i make my own keyboard like add UIView and add buttons?

You can create a custom keyboard, like the one used in calculator apps and so, it could be a uiview with custom keys

If i use my own, will apple accept my app for uploading on iTunes? Please clear my and if any helping material you've then kindly share with me. Thanks in advance.

If your custom keyboard is not misleading and is done in a proper way then it should not be rejected, read the following Custom iPhone Keyboard

Answer 2

1. There is no api that providing extra features and functionality for iPhone native Keyboard
2. You can make your own keyboard using VSKeypadView
3. Apple will accept the application as there are many applications implemented custom keyboard in the app store

Answer 3

You will notice that UITextView and UITextField both have optional variables of the form:

public var inputView: UIView?
public var inputAccessoryView: UIView?

You should do further research in how to use them. I think in particular inputAccessoryView into which you'd put your extra buttons.
