UIView has incorrect orientation

Question

I'm working on this cocos2D app that only supports landscape orientation. There is this UIView that is being displayed perpendicular, as if the device was in portrait orientation. I have two questions:

Why is why is it being displayed perpendicular?
Is it possible to get it to display properly without manually rotating the view?

Here is the code in the view controller:

// this method is called from init
-(void) addLoadingView {    
        CGSize size = [[CCDirector sharedDirector] winSize];

    _blockerView = [[[UIView alloc] 
        initWithFrame: CGRectMake(0, 0, 280, 60)] autorelease];
    _blockerView.backgroundColor = [UIColor colorWithWhite: 0.0 alpha: 0.8];
    _blockerView.center = CGPointMake(size.width/2, size.height/2);
    _blockerView.alpha = 0.0;
    _blockerView.clipsToBounds = YES;
    if ([_blockerView.layer respondsToSelector: @selector(setCornerRadius:)])
        [(id) _blockerView.layer setCornerRadius: 10];

    _blockerLabel = [[[UILabel alloc] initWithFrame: CGRectMake(0, 5, _blockerView.bounds.size.width, 15)] autorelease];
    _blockerLabel.text = NSLocalizedString(@"Please Wait...", nil);
    _blockerLabel.backgroundColor = [UIColor clearColor];
    _blockerLabel.textColor = [UIColor whiteColor];
    _blockerLabel.textAlignment = UITextAlignmentCenter;
    _blockerLabel.font = [UIFont boldSystemFontOfSize: 15];
    [_blockerView addSubview: _blockerLabel];

    UIActivityIndicatorView  *spinner = [[[UIActivityIndicatorView alloc]
        initWithActivityIndicatorStyle: UIActivityIndicatorViewStyleWhite] autorelease];

    spinner.center = CGPointMake(_blockerView.bounds.size.width / 2, _blockerView.bounds.size.height / 2 + 10);
    [_blockerView addSubview: spinner];
    [self.view addSubview: _blockerView];
    [spinner startAnimating];
}

-(void) showLoadingGraphics:(NSString*)textInView{
    _blockerView.alpha = 1.0;
    _blockerLabel.text = NSLocalizedString(textInView, nil);
}

Update

I found out that if it add it to the openGLView then it is fine.

[[[CCDirector sharedDirector] openGLView] addSubview: _blockerView];

instead of

[self.view addSubview: _blockerView];

works

I suspect the view its currently in got rotated somehow.

Screenshot? Is _blockerView the view you're talking about? Quick comment - you don't need to set the center of _blockerView if you've already initialized it using a certain frame. — sparkFinder
Yes, _blockerView is the one that is rotated. I didn't write this code. I just work here, lol. Thanks for the tip though. — Jay

Please check the view controller for a method called shouldAutorotateToInterfaceOrientation:. Yours should answer like this:

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

Is their a tab bar controller present? If so, that's a potential gotcha: all the view controllers of the tab bar need to agree on orientation.
