Thanks for the input. I was just trying to load a particular XIB based
on the device being used. Each XIB would communicate something
different. It sounds like I can scratch this idea for something
simpler using UIViewController. I'll reread the programming and
reference guides and rethink my solution. Again, thanks for the input!

I second the previous poster's opinion: view controllers are
definitely the way to go here. They'll let you take care of rotation
and plenty of other stuff: read the view controller programming
guide. Using a view controller gives you many more places to
customize what happens.
There's viewDidLoad for initial setup, viewDidUnload for cleanup,
viewWillAppear, viewDidAppear, and related methods for more frequent
stuff, you name it. See the documentation for UIViewController.
What you want to achieve is easily done in viewDidLoad, or if you
want to have complete control without using Interface Builder, in
loadView. Depending on how different your views are depending on the
device, there may be simpler solutions.
Good luck,
Hank

Hm, I opted to set the view's programmatically rather than through
a controller so I could control what view is initially displayed
depending on the device (iPhone, iPod, etc.). I'm assuming I will
be able to achieve something like this even when using view
controllers?

Hmm I have a few comments:
It look like you're seeing the superposition of two problems that
look like one:
1) The status bar is covering up the very top of your view in the
sim
2) The bottom button is 20px further from the bottom in the sim
The interface builder likes to make views default to a height of
460, not 480. I always change mine to 480 before I start using
them. From your pictures, it looks like this is the culprit -
that, and the status bar covering up the top. In order to change
it, you must disable the 'simulate status bar' option in the
view's inspector.
I believe that view is designed to be shown in a view controller
who takes the status bar into account already. I also believe that
you simply added the view as a subview of the window, which is
what caused the status bar to cover up the top. (also, the
interface builder shows you what the view would look like in a
view controller that takes the status bar into account)
From this, you have a few options:
1) Disable the status bar in your application, set the view's
"Simulated Interface Elements" to not show the status bar, then
change the hight of the view to 480. To disable the status bar in
your application, go to its info.plist, add a new row, scroll to
the bottom, select "Status Bar is Initially Hidden" and set it to
TRUE.
2) Use a view controller to show your view. I didn't fully
understand just what the controllers did until after a very long
time of tinkering, but they're a godsend... or, an apple-send in
this case. They'll help making stuff like that line up, though
only after you understand them.
or 3) Use both the above options (this is my recommendation)

When I run my app in the iPhone simulator the view seems to be
shifted up on the screen. If that doesn't make sense I've
uploaded some images. Take a look and see if you've run into this
before.
