irstViewController *fvc = [[FirstViewController alloc] init];
UINavigationController *navcon = [[UINavigationController alloc] initWithRootViewController:fvc];
[fvc release];

Example of [UINavigationBar barStyle].

The Apple Documentation says to use the following since UIBarStyleBlackTranslucent is deprecated:

navController.navigationBar.barStyle = UIBarStyleBlack;
navController.navigationBar.translucent = YES;
You could try shifting your view back in the correct place or try using the following:

navController.navigationBar.tintColor = [UIColor blackColor];
navController.navigationBar.translucent = YES;
