Question

我正在尝试使用Storyboard在导航视图中嵌入导航控制器。我将Container View添加到场景中，删除自动生成的View Controller，然后从Container View拖动到我的Navigation Controller，创建一个segue。

当我在模拟器中运行应用程序并转换到包含容器视图的场景时，我得到以下异常：

2018-04-28 15：22：40.278627-0400 Woofr [8977：18656423] ***由于未捕获的异常终止应用程序＆＃39; NSUnknownKeyException＆＃39;，原因：＆＃39; [setValue：forUndefinedKey： ]：此类不是密钥容器视图的键值编码兼容。＆＃39;

如果我只使用原始自动生成的View Controller将其作为测试运行，它就可以运行。如果我控制 - 从容器视图拖动到导航控制器而不删除自动生成的视图控制器，则会在故事板中替换segue，但在运行应用程序时会出现相同的异常。

Answer 1

在包含containerView的VC类中，请确保为其添加IBOutlet

@IBOutlet var containerView:UIView!

//

当你将一个containerView拖到一个视图并给它约束时，它会创建一个带有来自该容器的seg的VC View，单击destinationVC并从Editor-＆gt; EmbedIn-＆gt; NavigationController

//

在容器视图中嵌入NavigationController
