放松segue不工作iOS swift [英] Unwind segue not working iOS swift

问题描述

美好的一天，



这可能是一个愚蠢的问题，但我只是在3周前开始使用swift。我正在使用SWRevealViewController在我的应用程序上显示菜单。从这个菜单我将根据选择去一个特定的视图控制器。从那个选定的视图控制器，我想放松回主视图控制器（在启动应用程序时打开）。



如何达到展开方法，但没有任何反应？



我必须说unwind方法在Objective-C类中，因为SWRevealViewController是用objective-c编写的，而我的应用程序是用Swift编写的。我有桥接头。根据

Good day,

This may be a dumb question, but I only started with swift about 3 weeks ago. I am using SWRevealViewController to display a menu on my app. From this menu I am going to a certain view controller based on selection. From that selected view controller I would like to unwind back to the main view controller (Which is opened when launching the app).

How is it that the unwind method is reached, but nothing happens?

I must say that the unwind method is in an Objective-C class since the SWRevealViewController is written in objective-c and my app is written in Swift. I have bridging headers in place. Method is reached according to

printf("Unwind Method Called");

。



我们非常感谢任何帮助。



我尝试了什么：



我在故事板中实现了展开方法和正确连接的所有内容。我甚至在unwind方法下添加了一行打印到控制台并进行打印。但是，视图控制器不会重定向到第一个。

in the unwind method.

Any help would be greatly appreciated.

What I have tried:

I implemented the unwind methods and everything connected correctly in storyboard. I even added a line to print to the console under the unwind method and it prints. However, the view controller is not redirected to the first one.

推荐答案

在您的情况下，我认为您不会忽视视图。



你能告诉我代码，你是如何从第一个开始转向第二个的。



例如：如果使用这个

In your case, I think your are not dismissing the view.

Can you show me the code, that how you are moving to second one from first.

Example : If using this

self.present(ViewController, animated: false, completion: nil)

然后你需要在后退按钮上添加以下代码或提交任何回来。

then you need to add below code on back button or submit whatever for coming back.

dismiss(animated: false, completion: nil)

希望这可能会有所帮助。

Hope this may help.
