Iphone Navigation Bar not resize correctly

Question

Hi.

i have an application that must run on portrait and landscape.

All is working, but i have this issue:

i have the Navigation Controller in this way

immediately under it there is another view(fixed static position, overlaying the rear view) in the image, it contains the number "7" In this example, i have the following structure /rootController.view -subViewWithNavigationController -graySubView

when i rotate, i have this problem http_//img255.imageshack.us/i/schermata20100913a23531.png/

the ubViewWithNavigationController title shrink by about 10-15px and take all the view upper , so i find a white space between title and my graySubView. in interface builder, i used many config, now it's like

to set the title, i also use this snippet

    - (void)SetNavigationTitle:(NSString*)title AndSubtitle:(NSString*)subtitle {
if (subtitle == nil)
 {
  self.navigationItem.titleView = nil;
  self.navigationItem.title = title;
  return;
 }

 // set the default title anyway, so the next view controllers will have the correct text on their "back" button
 self.navigationItem.title = title;

 #define LEFT_OFFSET 15

 // Replace titleView
 CGRect headerTitleSubtitleFrame = CGRectMake(LEFT_OFFSET, 0, 200, 44);    
 UIView* _headerTitleSubtitleView = [[UILabel alloc] initWithFrame:headerTitleSubtitleFrame];
 self.navigationItem.titleView.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth;
 _headerTitleSubtitleView.backgroundColor = [UIColor clearColor];
 _headerTitleSubtitleView.autoresizesSubviews = NO;

 CGRect titleFrame = CGRectMake(LEFT_OFFSET, 10, 160, 24);  
 UILabel *titleView = [[UILabel alloc] initWithFrame:titleFrame];
 UIFont *font = [UIFont fontWithName:@"Georgia" size:20];
 titleView.backgroundColor = [UIColor clearColor];
 titleView.font = font;
 titleView.textAlignment = UITextAlignmentCenter;
 titleView.textColor = [UIColor whiteColor];
 titleView.shadowColor = [UIColor darkGrayColor];
 titleView.shadowOffset = CGSizeMake(0, -1);
 titleView.text = title;
 titleView.adjustsFontSizeToFitWidth = NO;
 [_headerTitleSubtitleView addSubview:titleView];
 [titleView release];

 CGRect subtitleFrame = CGRectMake(LEFT_OFFSET, 24, 160, 44-24);   
 UILabel *subtitleView = [[UILabel alloc] initWithFrame:subtitleFrame];
 subtitleView.backgroundColor = [UIColor clearColor];
 subtitleView.font = [UIFont boldSystemFontOfSize:13];
 subtitleView.textAlignment = UITextAlignmentCenter;
 subtitleView.textColor = [UIColor whiteColor];
 subtitleView.shadowColor = [UIColor darkGrayColor];
 subtitleView.shadowOffset = CGSizeMake(0, -1);
 subtitleView.text = subtitle;
 subtitleView.adjustsFontSizeToFitWidth = YES;
 [_headerTitleSubtitleView addSubview:subtitleView];
 [subtitleView release];

 self.navigationItem.titleView = _headerTitleSubtitleView;
 [_headerTitleSubtitleView release];}

also been taken from StackOverflow.

So, where i'm wrong? :-(

thanks for the help
