Remove ability for portrait orientation for app in iPhone SDK

Question

Is there a way where I can only allow my app viewable in landscape mode? I've managed to default the application's orientation to landscape, however in the iPad simulator, when I do Command->Arrow, the application rotates to portrait. I've removed the listings in the plist under "Supported interface orientations" for both of the Portrait entries, however that doesn't seem to've changed anything.

Any idea?

In your view controller, there's a delegate method for this:

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
    // Return YES for supported orientations
    return ((interfaceOrientation == UIInterfaceOrientationLandscapeLeft) || 
            (interfaceOrientation == UIInterfaceOrientationLandscapeRight);
}
