I do not know of any frameworks, but this would be a pretty small amount of code to get working. All you need is a view with a background colour with alpha < 1, and put some buttons on it. Then slide it in and out using UIView animations. Hey presto.

You can create the view in interface builder to save yourself some time, and put if off the top of the view. To animate it in, just use something like:

- (IBAction)menuButtonPressed:(id)sender
{
    CGRect menuFrame = self.menuView.frame;
    if (menuFrame.origin.y >= 0) {
        // menu is visible
        menuFrame.origin.y = -menuFrame.size.height;
    } else {
        // menu is invisible, slide it on screen
        menuFrame.origin.y = 0;
    }

    [UIView animateWithDuration:0.4
                     animations:^{
        self.menuView.frame = menuFrame;
    }];
}
