Hiding NavigationBar will hide your rightBarButtonItem too. One of the possible solutions is that you make the Navigation Bar transparent. You can use following code to do so:

[self.navigationController.navigationBar setBackgroundImage:[UIImage new] forBarMetrics:UIBarMetricsDefault];
self.navigationController.navigationBar.shadowImage = [UIImage new];
self.navigationController.navigationBar.translucent = YES;
self.navigationController.view.backgroundColor = [UIColor clearColor];
