iPhone SearchBar with Buttons Underneath?
<p>How would one implement a search field like the one used on the iPhone Mail application. When you attempt to search it shows up 4 buttons under the search bar with the fields you can search. The search bar actually moves up to cover the navigation bar and exposes those buttons.</p>

<p>I'd like to do something similar in my application where you can specify what exactly you are searching for. I think the mail search is a little difference since it also has a cancel button?</p>

<p>How would you accomplish this and what components would you use?</p>
