iphone - How to change keyboard background color in iOS?

Question

I would like to know how to change the keyboard background color programmatically in iOS? The background is normally grey but I have already seen black background (behind letters).

Answer 1

For the dark background use:

mytextfield.keyboardAppearance = UIKeyboardAppearanceAlert;
