View isn't rotating properly

Question

I have this code inside a UIViewController subclass:

- (id)init {
    self = [super init];

    if (self) {            
        self.view.frame = [PDToolbox screenFrame];
        self.view.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;

        self.view.backgroundColor = [UIColor redColor];
    }

    return self;
}

The only thing I have in terms of any rotation methods is this:

-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation {
    return YES;
}

Yet after the screen is rotated to landscape, doing an NSLog on the view shows this:

<UIView: 0x10061640; frame = (0 0; 320 480); transform = [0, -1, 1, 0, 0, 0]; autoresize = W+H; layer = <CALayer: 0x10061670>>

I don't understand why it's doing this transform thing, and not just rotating like normal? It means any views i place on top of it after the rotation and set to be the size of the view end up at a 320x480 position.

EDIT:

People aren't understanding. So I put a view on top of it, the same size as the UIView, using:

UIView *anotherView = [UIView alloc] initWithFrame:controller.view.bounds];
[controller.view addSubview:anotherView];

If I add anotherView in in portrait, anotherView appears in portrait, with the frame 320x480.

If i add anotherView in in landscape, anotherView appears in landscape, but still with the frame 320x480, becaus that's what the controller.view's frame is still, for some unknown reason.

Actually i dont understand your problem..What do you mean by this?"views i place on top of it after the rotation and set to be the size of the view end up at a 320x480 position" — Dinesh Raja
Are you adding this view directly to the window or something? This is very odd behaviour that's typically managed (correctly) by your view controller hierarchy. — Ash Furrow

What does your view/controller hierarchy look like? It looks to me like something is setting a 90° rotation transformation on your view, rather than changing the view's frame. If you're not doing that yourself, it's likely a parent view or view controller.
