iOS Invisible UIInterfaceOrientation?

[Darkroom]

i have a main view that presents a model view. the model view completely covers the main view. the model view works with orientation changes, but the main view does not. the problem is that in order to load the model view according to the current device's orientation, i (believe that i) have to also allow interface orientation changes to the main view, which requires lots of repositioning to make it look like it isn't really changing.

so is it possible to allow for orientation changes but disallow animation of any of the views on screen? like an invisible orientation switch?
