iphone - Stop automatic dismissal of keyboard on iOS/disablesAutomaticKeyboardDismissal not called

Question

I would like to be able to have another control become the first responder yet keep the keyboard showing to the user.

I found disablesAutomaticKeyboardDismissal in UIViewController and overrode it but it never get's called (iOS 5.0)

Is there a reason this method would not get called? Is there another way to keep the keyboard showing even though it's not required by the first responder?

虽然感觉有点像 hack 我所做的是在 UIView 上覆盖 canBecomeFirstResponder 以返回 YES 然后实现 UIKeyProtocol

但是在按键上什么也没做。这样键盘保持打开状态，但按键无关紧要。
