ios - 由于名称为 'NSInternalInconsistencyException' 的未捕获异常 'OverlayView' 而终止应用程序

Question

我打算使用自定义 View Koloda在我通过 Podfile 新创建的 swift xcode 项目中。 pod install后，在Main.storyboard中创建KolodaView并构建成功，运行时报错如下:

libc++abi.dylib: terminating with uncaught exception of type NSException

其中，OverlayView类可以在ViewController中被引用，这意味着第三方类在项目级别被正确引用。

演示项目是here

谁能给我一些提示，问题可能出在哪里？非常感谢!

Answer 1

此错误是由于您的包中没有名为 .xib 的 overlayView 文件，创建一个新文件 -> UserInterface -> View -> (将其重命名为 OverlayView)现在得到 OverlayView 并选择 View ，将其类更改为 OverlayView。
