由于名为'OverlayView‘的未捕获异常'NSInternalInconsistencyException’，正在终止应用程序

Question

我打算通过Podfile在我新创建的swift xcode项目中使用自定义视图Koloda。在pod install后，在Main.storyboard中创建KolodaView并构建成功后，运行时会报告异常，如下所示：

2016-08-20 09:44:38.918 MsgNotFree[25760:2220650] *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Could not load NIB in bundle: 'NSBundle </Users/jasonzhu/Library/Developer/CoreSimulator/Devices/DDE42B9D-6304-4552-AD30-A1BFA3A7B3E0/data/Containers/Bundle/Application/D1282CEB-9914-4C37-BCD2-DC05675C9FD1/MsgNotFree.app> (loaded)' with name 'OverlayView''

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

其中，OverlayView类可以在ViewController中引用，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

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