嘿，我无法弄清楚我遇到的错误。我的应用程序正在运行，但我不确定我做了什么，但它现在打不开，而是出现此错误:
Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<TaskViewController 0x16c9b0> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key projectToolBar.'
任何想法可能是什么问题？如果需要，我可以添加我的项目代码...
所以我看了看，在界面构建器/ Storyboard中有一个指向 projectToolBar 的链接，但在头文件中没有相应的行。我在 IB 中删除了问题，但是，现在我收到一个新错误并且它仍然无法正常工作。
*** Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<TaskViewController 0x132dd0> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key projectView.'
这是我的 taskviewController 类:
