线程1：在Obj C上发出SIGABRT信号错误

Question

我在网站上搜索了这个问题，但我无法解决问题。所以我想问我怎么解决这个问题？

我有一个导航控制器和一个视图控制器。我在导航控制器上添加了一些元素，它正在工作但是当我添加ViewController并将其与导航控制器连接时，我发现了一个问题。我用segue连接它们，我想从导航控制器的元素传递到视图控制器。构建失败，我接受此错误代码;

my viewControllers

Answer 1

将导航控制器嵌入到您的源视图控制器

1. 选择源视图控制器
2. 转到编辑 - ＆gt; 嵌入 - ＆gt; 导航控制器。

Answer 2

从错误消息中我可以说问题是你的segue的源控制器没有包含在NavigationController中。要解决此问题，请在InterfaceBuilder中选择相应的控制器，打开Editor菜单，然后选择Embed in，然后选择Navigation Controller。这将创建一个托管ViewController的新NavigationController，并且还应自动更新和修复segue。
