Set UINavigationBar's background image

Question

I have this piece of code:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    if([[UINavigationBar class] respondsToSelector:@selector(appearance)]
    {
        [[UINavigationBar appearance] setBackgroundImage:[UIImage imageNamed:@"bar-mid.png"] forBarMetrics:UIBarMetricsDefault];
    }
    //[[UINavigationBar appearance] setTintColor:[UIColor redColor]];
    return YES;
}

It works If I try to set the TintColor to red (in the commented line of code), but If i try to set a background image it doesn't work! Yes, I have the "bar-mid.png" image in "Supporting Files > Images". I use storyboard. This is the result:

Can you help me? Thanks!

Have you checked that it is being called within the "if" statement? — Ōkami
Presumably you've also tried using bar-mid.png elsewhere in the app just to rule that out? — Ōkami

I can't understand why, but I changed the name of the two images in "greenNavigation.png" and "[email protected]" , I changed [UIImage imageNamed:@"bar-mid.png"] in [UIImage imageNamed:@"greenNavigation.png"] and now it works. Someone know why?
