怎么在模态推出的controller 上添加一个navigation

    

    SetViewController * vc = [[SetViewController alloc] init];

    navigation = [[UINavigationController alloc] initWithRootViewController:vc];

//    [self.navigationController pushViewController:navigation animated:YES];

    

    vc.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;

    [self presentViewController:navigation animated:YES completion:^{

        

    }];

 

vc之后的controller就可以用navigation推出了
