Window subview not rotating after orientation of the device changes

Question

I'm creating an UIView with a label inside AppDelegate and displaying it like this:

    [window addSubview:self.roundedCornerView];

Problem is when I rotate the device the view with label don't rotate at all. The text in the label is in wrong orientation as well. Window in my application got another subview which is the UIViewControllers subview and it is rotating fine.

Do I need to create another UIViewController in my AppDelegate and attach created view to it, then subclassing it and allowing for interface orientation in order to get roundedCornerView to rotate?

UPDATE Ok I've tried to do this by creating new ViewController and sublcassing it here is code in my AppDelegate:

    ActivityIndicatorWithLabelViewController *aiWithLabel = [[[ActivityIndicatorWithLabelViewController alloc] init] autorelease];
aiWithLabel.textOfTheLabel = text;

[window addSubview:aiWithLabel.view];

The ActivityIndicatorWithLabelViewController class is visible here:

    if (UIInterfaceOrientationIsLandscape(interfaceOrientation)) {
        [self.textActivityIndicatorLabel removeFromSuperview];
        [self.textActivityIndicatorLabel release];

        self.textActivityIndicatorLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 50, 50)];
        self.textActivityIndicatorLabel.backgroundColor = [UIColor clearColor];
        self.textActivityIndicatorLabel.textAlignment = UITextAlignmentCenter;
        self.textActivityIndicatorLabel.textColor = [UIColor whiteColor];
        self.textActivityIndicatorLabel.font = [UIFont systemFontOfSize:22];
        self.textActivityIndicatorLabel.text = @"Landscape";
        [self.roundedCornerView addSubview:textActivityIndicatorLabel];         

        NSLog(@"LANDSCAPE");
    }
    NSLog(@"ENTERING SUPPORTED ORIENTATION!");
    return YES;
}

@end

As you see there is some debug code in here. When I'm rotating the device from potrait to landscape I get ENTERING SUPPORTE ORIENTATION! as well as LADNSCAPE NSLog. Removing label is working fine, but when I'm adding new one it is still presented (the text) in wrong orientation. What I am doing wrong?

Answer 1

UIWindow should only have one subview which defines the root UIViewController. I believe that UIWindow only forwards rotation events to its first subview.

Create a single container UIView and move your subviews into it.
