I cooked a solution that might be more what you're looking for.

• Create a custom subclass of UINavigationBar.
• Override setBarStyle: as follows

code:

- (void)setBarStyle:(UIBarStyle)style {
    //Fade our content, ie background, from one style to another
    CATransition *transition = [[CATransition new] autorelease];
    transition.type = kCATransitionFade;
    transition.duration = 0.2;
    [self.layer addAnimation:transition forKey:@"content"];

    [super setBarStyle:style];
}

• Configure your nav controllers to use this subclass
  • In IB, you can just set the class in the inspector
