I want to create a simple view over keyboard, when users tap \"Attach\" button in inputAccessoryView. Something like this:

Is there an easy way to do it? O

Answer 1

While this can be possible with accessing the topmost window, I would avoid doing this, as it clearly interferes with Apple's guidelines.

What I would do is dismissing the keyboard and replacing its frame with a view with same dimensions.

The keyboard's frame can be accessed from keyboard notifications listed here, their userInfo contain a key that can be accessed with UIKeyboardFrameEndUserInfoKey.
