Animate subview when added

[ethanhayon]

Hi,

I'm trying to replicate the multitasking bar within my application. When the user taps a button, a menu will drop down from the top of the application. I have created a UIScrollView to test with, but I don't know how to make it slide down from the top of the screen.
I am thinking about using subviews that I could animate using UIView commitAnimations.

Is there any sample code that replicates the multitasking bar effect?
What is the best way to replicate this effect?

Thanks in advance,
Ethan
