How can I interact with "iPad keyboard hiding button" programmatically?

Question

There is a button at bottom right of iPad keyboard which is to hide the keypad.

enter image description here

How can I interact with it programmatically? (get the button then send UIControlEventTouchUpInside to it).

Does anyone know this?

[Edit] In my case, the keyboard is shown on a modal view.

is this a different behavior than sending -(void)dismissFirstResponder to the view that you are editing? — Grady Player, Apr 29 '11 at 06:50
In my case, resignFirstResponder does not work since I want to hide iPad keyboard on a modal view (UIModalPresentationFormSheet) to display UIDatePicker, so I would like to fire that event to hide keypad if possible — Son Nguyen, Apr 29 '11 at 07:07
If you present the UIDatePicker and make it the first responder, the keyboard should go away, no? Why isn't that good enough? — ipmcc, May 01 '11 at 15:03

Overriding disablesAutomaticKeyboardDismissal to return NO as below allows you to dismiss the keyboard when you resignFirstResponder, even when your UITextView is on a modal view. You should put this code to your view controller, from which you initiate the keyboard:

- (BOOL)disablesAutomaticKeyboardDismissal {
    return NO;
}

Something like this? I can't remember where I found this code but I used it to toggle the on-screen keyboard because it would be hidden by default if a bluetooth one was connected.

- (void) toggleKeyboard(UIKeyboardImpl * keyImpl){

    if (UIKeyboardAutomaticIsOnScreen()) {
        UIKeyboardOrderOutAutomatic();
    } else {
    UIKeyboardOrderInAutomatic();
}

Edit

I found where I got this code from. It works fine but the catch is that you need to import the private framework GraphicsServices, which would most likely get your app rejected from the App store.

In general, you would send the resignFirsResponder message to the active input view.

I tried this already, but in my case, the keyboard on a modal view does not take effect. – Son Nguyen May 24 '11 at 10:13
