iOS 8 has arrived with so many new features. Among these, there's the ability to add keyboards/third-party keypads. Isn’t this something you had been waiting for long?
Cool as the feature might be, it comes with a couple of hooks right now. The first is that, since iOS 8 and the whole idea of a keyboard API is so new, third-party keypads you install can be slow, laggy or causing issues. The second one is about data security: if you allow full access to the keypads, Apple says it's possible for the developers to track what you type on their keyboards. Whatever be the case, you've added a keyboard and you want to remove it. How to do that?
How To Delete Third Party Keyboard in iOS 8 on iPhone and iPad:
Step #1. Tap on Setting
Step #2. Tap on General
Step #3. Scroll down and tap on Keyboard
Step #4. Tap on Keyboards
Step #5. Tap on Edit (Right on top)
Step #6. Tap on the “-” sign right next to the keypad you want to delete.
Step #7. Tap on Delete
Apple tries to be extremely cautious about privacy. That they even allowed third-party keypads to exist in iOS comes at a price. Apple does not – by default – let third-party keypads work when you are typing sensitive information (like passwords and credit card info).
When you are about to enter sensitive info, Apple shows only the stock keypad. The number pad is also only that of Apple's and it's non-customizable.
However, you can bypass this a bit. In Settings → General → Keyboard → Keyboards → <Third Party Keyboard>, you can switch on Allow Full Access to let the third-party keypad take over completely. You should do this only if you trust the app developer completely.
