This is an old answer and is no longer working on iOS 9. For an updated solution, see my answer here.
It is a gray-area, but certainly possible.

Register for notification on keyboard showing:
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillShow:) name:UIKeyboardWillShowNotification object:nil];
Then:
- (void)keyboardWillShow:(NSNotification *)note {
[self performSelector:@selector(removeBar) withObject:nil afterDelay:0];
}
- (void)removeBar {
// Locate non-UIWindow.
UIWindow *keyboardWindow = nil;
for (UIWindow *testWindow in [[UIApplication sharedApplication] windows]) {
if (![[testWindow class] isEqual:[UIWindow class]]) {
keyboardWindow = testWindow;
break;
}
}
// Locate UIWebFormView.
for (UIView *possibleFormView in [keyboardWindow subviews]) {
// iOS 5 sticks the UIWebFormView inside a UIPeripheralHostView.
if ([[possibleFormView description] rangeOfString:@"UIPeripheralHostView"].location != NSNotFound) {
for (UIView *subviewWhichIsPossibleFormView in [possibleFormView subviews]) {
if ([[subviewWhichIsPossibleFormView description] rangeOfString:@"UIWebFormAccessory"].location != NSNotFound) {
[subviewWhichIsPossibleFormView removeFromSuperview];
}
}
}
}
}
