How to set the UIKeyboard-Style for the whole App?

Question

I am currently trying to set the keyboard style globally, but my approach does not work. I tried it using UIAppearance and put this line of code inside the AppDelegate :

[[UITextField appearance] setKeyboardAppearance:UIKeyboardAppearanceAlert];

But what I got on the console is the following:

[UISearchBarTextField _UIAppearance_setKeyboardAppearance:]: unrecognized selector sent to instance 0xa1897e0

Any ideas how to solve this?

UIAppearance only works with methods that are specifically marked with the macro UI_APPEARANCE_SELECTOR to be compatible, and unfortunately keyboardAppearance is not one of them.

The best way to get what you want is to subclass UITextField and set keyboardAppearance = UIKeyboardAppearanceAlert; in the the subclass's init and initWithFrame: methods. Then exclusively use your class wherever you would have used UITextField in the app.
