How to zoom in/out in Xcode 4.1 Interface Builder window to see multiple UIViews

I'm building a xib with multiple views, one oriented for landscape and another for portrait. I'd like to be able to zoom out from the Interface Builder window to see both and then zoom in on one of the views to work on it, rinse, repeat.开发者_如何转开发 Can this be done?

This is not possible as far as I know, but Xcode 4.2 allows you to develop your iOS applications using "storyboards", which is similar (and has many other benefits).
