Why view size is 703x768 for iPad app in Interface Builder?
===

Im working on my first iPad app.
By default Xcode generated for me a starting point project, which contains the basic template for the Split view controller.

I am focusing on the detail view controller right now (my first app version may only utilize this view).

Anyway, I noticed that in the Xcode integrated Interface Builder the detail view is 703 (width) x 768 (height).

First question: why is the width 703?

Now, the view in the IB shows a portrait layout of the view. So it's even more odd that the width is greater than the height (when it should be the other way around).

I actually expected the width to be 768, and the height 1024.

Thanks.
