View controller does not receive -shouldAutorotateToInterfaceOrientation: messages on second boot?

Question

I have UIViewControllerone that I use to control a popup view for viewing images throughout the application. It supports autorotation, as it automatically aligns the image so that it matches regardless of orientation. This works fine, but only for the first time I initialize and show the view controller. When it closes, I remove UIViewfrom my view hierarchy and release the view controller, but the next time I create an instance and add it to my view hierarchy, it will stop receiving messages -shouldAutorotateToInterfaceOrientationwhen the phone is rotated.

This is how I create the instance and show it:

popupVC = [[PopupVC alloc] init];
[popupVC viewWillAppear:NO];
[[[UIApplication sharedApplication] keyWindow] addSubview:popupVC.view];
[popupVC viewDidAppear:NO];

so I delete / release it when I finish:

[popupVC viewWillDisappear:NO];
[popupVC.view removeFromSuperview];
[popupVC viewDidDisappear:NO];
[popupVC release];
popupVC = nil;

I tried [[UIApplication sharedApplication] keyWindow]iterating through subviews to see, somehow my popup view is not on top, but it always is. And each time it has different addresses, so I know that this is a different instance of the view controller class.

As requested, here is the complete method loadViewfrom PopupVC:

- (void)loadView {

    UIView *myView = [[UIView alloc] initWithFrame:[UIScreen mainScreen].applicationFrame];
    myView.backgroundColor = self.overlayColor;
    myView.autoresizesSubviews = NO;
    myView.hidden = YES;
    myView.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth;
    self.view = myView;
    [myView release];

    _isVisible = NO;

    UIView *myMaskView = [[UIView alloc] initWithFrame:self.view.bounds];
    myMaskView.backgroundColor = [UIColor clearColor];
    myMaskView.clipsToBounds = YES;
    myMaskView.hidden = YES;
    myMaskView.autoresizesSubviews = NO;
    myMaskView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
    [self.view addSubview:myMaskView];
    self.imageMaskView = myMaskView;
    [myMaskView release];

    UIImageView *myImageView = [[UIImageView alloc] initWithFrame:CGRectZero];
    myImageView.center = self.view.center;
    myImageView.hidden = NO;
    myImageView.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleHeight;
    [self.imageMaskView addSubview:myImageView];
    self.imageView = myImageView;
    [myImageView release];

    UIButton *myImageButton = [UIButton buttonWithType:UIButtonTypeCustom];
    myImageButton.frame = self.view.frame;
    myImageButton.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleHeight;
    [myImageButton addTarget:self action:@selector(clickImage:) forControlEvents:UIControlEventTouchUpInside];
    [self.imageMaskView addSubview:myImageButton];
    self.imageButton = myImageButton;

    UIActivityIndicatorView *myActivityView = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge];
    myActivityView.hidden = YES;
    [self.view addSubview:myActivityView];
    myActivityView.center = self.view.center;
    self.activityView = myActivityView;
    [myActivityView release];
}

, ​​ 3.0. NSNotificationCenter beginGeneratingDeviceOrientationNotifications.

- (void)viewWillAppear:(BOOL)animated {
