title: How to slide in a UIView in a portrait mode application?
body: <p>I am working on an iPhone application that runs in portrait mode only. This app have only view controller and 1 interface file (.xib). I want to slide in some additional views when user taps on button on either toolbar / navigation bar. Let's say like info button on navigation bar. When I click it UIView should slide in from bottom. And when user taps on done button on that view that view slides down. I have made separate uiview for those views in same xib. I also looked into couple of transition examples by others but could not got that concept. Can any one give me some pointers on this ?</p>
