I have an app that has a centre view with two views off to each side of it. I want to have two navigation bar buttons, left and right which push a new navigation controller
To get the "pointy" type button you need to use a different method.
In your AppDelegate:
UITableViewController *first = [[RootViewController alloc] initWithStyle:UITableViewStylePlain];
UITableViewController *second = [[SomeOtherViewController alloc] initWithStyle:UITableViewStylePlain];
NSArray *stack = [NSArray arrayWithObjects: first, second, nil];
UINavigationController *nav = [[UINavigationController alloc] init];
[nav setViewControllers:stack animated:NO];
