What is the iPhone's default keyboard animation rate?

A while ago I remember seeing a constant of some kind that defined the animation rate of the Keyboard on the iPhone and I can not for the life of me remember where I saw it....any insight?

How do I get my keyboard back to normal on iPhone?

Go to Settings > Accessibility > Keyboards, tap Full Keyboard Access, then turn on Full Keyboard Access.

Can I adjust iPhone keyboard?

Go to Settings > General > Keyboard > Keyboards. Tap a language at the top of the screen, then select an alternative layout from the list.

- (NSTimeInterval)keyboardAnimationDurationForNotification:(NSNotification*)notification {     NSDictionary* info = [notification userInfo];     NSValue* value = [info objectForKey:UIKeyboardAnimationDurationUserInfoKey];     NSTimeInterval duration = 0;     [value getValue:&duration];     return duration; }
