u：使用

UINib（nibName:nibName，bundle:nil）。实例化所有者（nil，options:nil）

，这比NSBundle版本快。@Garfbargle这似乎满足了您可以在IB中设计并在情节提要中呈现的要求。基本上，您完全按照为XIB所做的操作，并将

@IBDesignable放在类上。

您还必须实现

init（frame:）

，但除此之外，它工作得非常好！谢谢您可能希望添加一个使用Swift约束的示例，正如您在Obj-C答案（有和没有VFL）中所做的那样。我回答了自己的问题，看起来我在阅读这些SO文章之前设置了出口，目的是设置文件所有者，而不是视图。在我断开所有插座的连接，确保文件所有者正确，然后重新添加所有插座后，它就工作了。设置文件所有者和自定义类之间有什么区别？我在界面生成器中也没有看到预览。Xcode 9代码在运行时可以工作，但在我的Xcode 9中，它在模块行下显示“可设计构建失败”。谢谢！你可能想为那些不想使用VFL的人添加一个不使用VFL的示例。我无法让它在Xcode8/Swift3中工作。运行应用程序时工作正常，但不会显示在情节提要中。对我来说工作正常。如果您试图查看xib上的更改，它将不会显示。在其他控制器内添加一个视图，然后将该视图的类设置为

DesignableXibView

。构建项目以查看更改。对我也很有用。只需将DesignableXibView添加到我当前的故事板中，如Garfbargle postJust me在运行时获取“无法加载捆绑包中的NIB”的步骤5所述？@Jonny我认为

String（description:type（of:self））

应该可以安全地完成此操作
