Is there a way to prevent the keyboard from dismissing?

I realize that this is the inverse of most posts, but I would like for the keyboard to remain up even if the 'keyboard down' button is pressed.

Specifically, I have a view with two UITextFields. With the following delegate method

- (BOOL)textFieldShouldReturn:(UITextField *)textField {
    return NO;
}

I am able to keep the keyboard up even if the user presses the Done button on the keyboard or taps anywhere else on the screen EXCEPT for that pesky keyboard down button on the bottom right of the keyboard.

I am using this view like a modal view (though the view is associated with a ViewController that gets pushed in a UINavigationController), so it really works best from a user perspective to keep the keyboard up all of the time. If anyone knows how to achieve this, please let me know! Thanks!

UPDATE Still no solution! When Done is pressed, it triggers textFieldShouldReturn, but when the Dismiss button is pressed, it triggers textFieldDidEndEditing. I cannot block the textField from ending editing or it never goes away. Somehow, I really want to have a method that detects the Dismiss button and ignores it. If you know a way, please enlighten me!

There IS a way to do this. Because UIKeyboard subclasses UIWindow, the only thing big enough to get in UIKeyboard's way is another UIWindow.

- (void)viewDidLoad {
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(coverKey) name:UIKeyboardDidShowNotification object:nil];
    [super viewDidLoad];
}

- (void)coverKey {
    CGRect r = [[UIScreen mainScreen] bounds];
    UIWindow *myWindow = [[UIWindow alloc] initWithFrame:CGRectMake(r.size.width - 50 , r.size.height - 50, 50, 50)];
    [myWindow setBackgroundColor:[UIColor clearColor]];
    [super.view addSubview:myWindow];
    [myWindow makeKeyAndVisible];
}

This works on iPhone apps. Haven't tried it with iPad. You may need to adjust the size of myWindow. Also, I didn't do any mem management on myWindow. So, consider doing that, too.
