How to switch orientations from within a view controller that isn't the root one

Question

I'm having troubles finding a solution to being able to change my orientation in a view controller that isn't the root one. For example, in the utility project which has a root view controller, main view controller for the main view, and a flipside view controller for the flipside view, the only place I can control the orientation is from the root view controller. Implementing the code in either the main or flipside views does nothing to limit or enable the orientations.

What I would like to do is be able to is have the main view load in landscape and the flipside view in portrait. Is this possible, or do I need to somehow reload the root view controller with different orientation settings when I switch between main and flipside views?

EDIT: To clarify, I want to lock the main view into only a landscape orientation, and the flipside view into portrait - these views shouldn't be able to rotate. - Thanks.

In your "main window".m file implement the following method.

-(BOOL)shouldAutorotateToInterfaceOrientation:UIInterfaceOrientation)interfaceOrientation 
{ 
    return (interfaceOrientation == UIInterfaceOrientationLandscapeRight);  // or whatever orientation is needed
}

In your "flipside view".m file implement the following method.

-(BOOL)shouldAutorotateToInterfaceOrientation:UIInterfaceOrientation)interfaceOrientation 
{ 
    return (interfaceOrientation == UIInterfaceOrientationPortrait);
}

In your application delegate or somewhere else in your startup process you can call the following method to set the interface orientation to landscape on startup:

[application setStatusBarOrientation:UIInterfaceOrientationLandscapeRight];  // should match the first method above.

Hope this helps.
