ios - ViewController层次结构-从堆栈中删除UISplitviewController

我的应用程序有一个登录视图，一个加载视图，一个拆分视图和一个菜单视图。

启动时，初始视图是登录视图。用户成功登录后，将进入加载视图。加载数据后，我将显示拆分视图。在拆分视图上，我有一个模态显示的菜单。菜单选项包括注销。用户注销后，我想返回登录视图。到现在为止还挺好。

问题是，当我检查视图层次结构时，拆分视图仍位于登录视图下方。从理论上讲，用户可以通过这种方式创建具有无限数量的分层视图的情况。

如何使用户返回登录视图并关闭拆分视图？

我正在使用情节提要和segues进入拆分视图。登录视图将推送到加载视图，而加载视图将推送到拆分视图。我在自定义模式表示控制器中显示模式菜单。

                ViewController4 *viewController4 = [storyboard instantiateViewControllerWithIdentifier:@"VC4"];

                viewController4.delegate=self;

                [self.navigationController presentViewController:viewController4 animated:YES completion:nil];
            }

            -(void)completed
            {
                [self.navigationController popToRootViewControllerAnimated:YES];

            }

            //VC4
            //In .h file
            @protocol  ViewController4Delegate

        -(void)completed;

        @end

        @interface ViewController4 : UIViewController

                [self dismissViewControllerAnimated:NO completion:^{

                    if(delegate)
                    {
                        [delegate completed];
                    }

                }];
