在UIStoryboard中按下到根视图控制器 [英] Push to root View controller in UIStoryboard

问题描述

我的故事板结构中有 ViewControllers 的层次结构。
A-B-C-D 。 A 嵌入了 NavigationController ，流程一直持续到 D viewController 。所有四肢视图通过segues附加。现在我在 D viewController ，我在 D 的按钮上定义了一些操作，它应该直接带我到 A viewController 即 rootViewController 或 B 的viewController 。那怎么能实现这一点呢。我尝试了一切，但没有成功。

I have hierarchy of ViewControllers in my storyboard structure. It is A-B-C-D. A is embed with NavigationController and the flow goes on till D viewController. All fours view attached through segues. Now I am on D viewController, I defined some action to the button of D that It should take me directly to A viewController that is rootViewController or B viewController. Then how can I achieve this. I tried everything but didn't succeed.

我想要的东西应该不会打扰 ABCD 流程，它应该带我去 D 的 viewController 。

I want something like it should not disturb A-B-C-D flow and it should take me to A viewController from D.

推荐答案

右键单击D viewcontroller并将i拖到A viewcontroller。

Right click on your D viewcontroller and drag i to your A viewcontroller.

然后单击刚刚创建的行上显示的对象。

Then click on the object which appears on the line you just created.

在属性检查器中的storyboard segue标识符中写入类似DtoA的内容。

Write something like DtoA in the storyboard segue identifier in the attributes inspector.

现在在D视图控制器中，只需：

Now in D view controller, just do:

[self performSegueWithIdentifier:@"DtoA" sender:self];

如果您希望以旧式方式弹出以前的viewcontroller，例如从D到B ：

And if you instead wish to pop to a previous viewcontroller the old fashioned way, like from D to B:

UINavigationController* navController = self.navigationController;
UIViewController* Bviewcontroller = [navController.viewControllers objectAtIndex:1];
[navController popToViewController:controller animated:YES];
