Question

-(void)keyboardWillShow : (NSNotification *)sender {
    @try  {
//      NSLog(@"notification in first view");
        for (UIWindow *keyboardWindow in [[UIApplication sharedApplication] windows]) { 
            for (UIView *keyboard in [keyboardWindow subviews]) {
                if([[keyboard description] hasPrefix:@"<UIKeyboard"] == YES) {
                    NSValue *v = [[sender userInfo] valueForKey:UIKeyboardBoundsUserInfoKey];
                    CGRect kbBounds = [v CGRectValue];
                    if(keyboardToolbar == nil) {
                        keyboardToolbar = [[UIToolbar alloc] initWithFrame:CGRectZero];
                        keyboardToolbar.barStyle=UIBarStyleBlackOpaque;
                        keyboardToolbar.tintColor = [UIColor colorWithRed:0.6 green:0.2 blue:0.6039 alpha:1];
                        UIBarButtonItem *barButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"Done" style:UIBarButtonItemStyleBordered target:self action:@selector(dismissKeyboard)];
                        UIBarButtonItem *flex = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
                        NSArray *items = [[NSArray alloc] initWithObjects:flex, barButtonItem, nil];
                        [keyboardToolbar setItems:items];
                        [items release];
                    }               
                    [keyboardToolbar removeFromSuperview];
                    keyboardToolbar.frame = CGRectMake(0, 0, kbBounds.size.width, 45);
                    [keyboard addSubview:keyboardToolbar];
                    keyboard.bounds = CGRectMake(kbBounds.origin.x, kbBounds.origin.y, kbBounds.size.width, kbBounds.size.height + 87);

                    for(UIView* subKeyboard in [keyboard subviews]) {
                        if([[subKeyboard description] hasPrefix:@"<UIKeyboardImpl"] == YES) {
                            subKeyboard.bounds = CGRectMake(kbBounds.origin.x, kbBounds.origin.y - 45, kbBounds.size.width, kbBounds.size.height);  
                        }                       
                    }
                }
            }
        }
    } @catch (NSException * e) {
//      NSLog(@"Problem in keyboardWillShow:%@",e);

Answer 1

You can try with

if ([[currentWindow description] hasPrefix:@"<UITextEffectsWindow"])
        {
            NSLog(@"Key board found");
}

But you cannot hide I think. You can put your custom view on it but hide the UIKeyboard I don't think it will work for iOS 4.
