How to find UIWebView toolbar (to replace them) on iOS 6? - iphone

Question

I have tried the following code from another application but it doesn't find anything. Why? How to get access to the UIWebView toolbar?
- (UIToolbar *)findVirginWebKeyboardToolbar:(UIView *)parent
{
if ([parent isKindOfClass:[UIToolbar class]]) {
UIToolbar *tb = (UIToolbar *)parent;
if ([tb.items count] == 1 && [((UIBarButtonItem *)[tb.items objectAtIndex:0]).customView isKindOfClass:[UISegmentedControl class]]) {
return tb;
}
}
for (UIView *view in parent.subviews) {
UIToolbar *tb = [self findVirginWebKeyboardToolbar:view];
if (tb) return tb;
}
return nil;
}
- (void)removeKeyboardBar {
UIView *keyboardWindow = nil;
for (UIWindow *testWindow in [[UIApplication sharedApplication] windows]) {
keyboardWindow = testWindow;
UIToolbar *toolbar = [self findVirginWebKeyboardToolbar:keyboardWindow/*subviewWhichIsPossibleFormView*/];
if (toolbar) {
itemsArray = [NSArray arrayWithObjects:button1, button2, button3, nil];
[toolbar setItems:itemsArray];
}
}
}

With the following code you should be able to remove the toolbar that is above the keyboard.
-(void)viewWillAppear:(BOOL)animated{
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(keyboardWillShow:)
name:UIKeyboardWillShowNotification
object:nil];
}
- (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 *formView in [keyboardWindow subviews]) {
// iOS 5 sticks the UIWebFormView inside a UIPeripheralHostView.
if ([[formView description] rangeOfString:#"UIPeripheralHostView"].location != NSNotFound) {
for (UIView *subView in [formView subviews]) {
if ([[subView description] rangeOfString:#"UIWebFormAccessory"].location != NSNotFound) {
// remove the input accessory view
[subView removeFromSuperview];
}
else if([[subView description] rangeOfString:#"UIImageView"].location != NSNotFound){
// remove the line above the input accessory view (changing the frame)
[subView setFrame:CGRectZero];
}
}
}
}
}
