[UIView setAnimationDuration:1.0];

[UIView setAnimationDelegate:self];
[menuView setAlpha:0];

When you tap showMenuView, do as following,

- (IBAction)showView:(id)sender 
{
    [self.view addSubview: menuView];
    CGRect rect = menuView.frame;
    rect.origin.y = 480;
    menuView.frame = rect;
    [UIView beginAnimations:@"ShowView" context:nil];
    [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
    [UIView setAnimationDuration:0.5]; 
    rect.origin.y = 0;
    menuView.frame = rect;
    [UIView commitAnimations];
}

And to hide,

- (IBAction)hideView:(id)sender 
{
    CGRect rect = menuView.frame;
    [UIView beginAnimations:@"HideView" context:nil];
    [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
    [UIView setAnimationDuration:0.5]; 
    [UIView setAnimationDelegate:self];
    [UIView setAnimationDidStopSelector:@selector(animationDidStop:finished:context:)];
    rect.origin.y = 480;
    menuView.frame = rect;
    [UIView commitAnimations];
}

- (void)animationDidStop:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context
{
    [menuView removeFromSuperview];
}
