I have done this. Basically you add your own button as a subview of the UIKeyboard like this:

// This function is called each time the keyboard is going to be shown
- (void)keyboardWillShow:(NSNotification *)note {

// Just used to reference windows of our application while we iterate though them
UIWindow* tempWindow;

// Because we cant get access to the UIKeyboard throught the SDK we will just use UIView. 
// UIKeyboard is a subclass of UIView anyways
UIView* keyboard;

// Check each window in our application
for(int c = 0; c < [[[UIApplication sharedApplication] windows] count]; c ++)
{
    // Get a reference of the current window
    tempWindow = [[[UIApplication sharedApplication] windows] objectAtIndex:c];

    // Loop through all views in the current window
    for(int i = 0; i < [tempWindow.subviews count]; i++)
    {
        // Get a reference to the current view
        keyboard = [tempWindow.subviews objectAtIndex:i];

        // From all the apps i have made, they keyboard view description always starts with 

Hope that's clear.
