Well you can animate the size of your window to simulate the slide from top like this:

[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.3];
myView.frame = CGRectMake(0, buttonHeight+buttonTop, myView.frame.size.width, viewTargetHeight);
[UIView commitAnimations];

Make sure you set the view height to 0 when you create it.

To scroll it back up just do the opposite

[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.3];
myView.frame = CGRectMake(0, buttonHeight+buttonTop, myView.frame.size.width, 0);
[UIView commitAnimations];

If you actually want your new view to slide you can try animating both the size and the position and you'll also probably need to clip your animated view with another view.
