Is there a documented way to set the iPhone orientation?

Question

I have an app where I would like to support device rotation in certain views but other don\'t particularly make sense in Landscape mode, so as I swapping the views out I wou

This works for me (thank you Henry Cooke):

The aim for me was to deal with landscape orientations changes only.

init method:

[[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];
[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(orientationChanged:)
                                             name:UIDeviceOrientationDidChangeNotification
                                           object:nil];

- (void)orientationChanged:(NSNotification *)notification {    
    //[[UIDevice currentDevice] endGeneratingDeviceOrientationNotifications];
    UIDeviceOrientation orientation = [UIDevice currentDevice].orientation;
    CGRect bounds = [[ UIScreen mainScreen ] bounds ];
    CGAffineTransform t;
    CGFloat r = 0;
    switch ( orientation ) {
        case UIDeviceOrientationLandscapeRight:
            r = 0;
            NSLog(@"Right");
            break;
        case UIDeviceOrientationLandscapeLeft:
            r  = M_PI;
            NSLog(@"Left");
            break;
        default:return;
    }

    t = CGAffineTransformMakeRotation( r );

    UIApplication *application = [ UIApplication sharedApplication ];
    [ UIView beginAnimations:@"InterfaceOrientation" context: nil ];
    [ UIView setAnimationDuration: [ application statusBarOrientationAnimationDuration ] ];
    self.view.transform = t;
    self.view.bounds = bounds;
    [ UIView commitAnimations ];

    [ application setStatusBarOrientation: orientation animated: YES ];
}
