错误：此类不是关键项目ToolBar的关键字编码兼容代码？
嘿，我不知道我得到一个错误。 我有我的应用程序工作，然后我不知道我做了什么，但现在不会打开，而是我得到这个错误：
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？ 我可以添加我的项目代码，如果我需要…
编辑：
所以我看着，在界面生成器/故事板中有一个projectToolBar的链接，在头文件中没有相应的行。 我删除了在IB的问题，但是，现在我得到一个新的错误，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：

@结束
最有可能的是你有一个xib文件，其中包含一个仍然连接到一个名为projectToolBar （现在不存在）的sockets的projectToolBar 。
您删除了IBOutlet UIToolBar *projectToolBar; 从你的TaskViewController.h文件。
你应该考虑使用源代码控制pipe理，所以你可以看到你做了什么。 😉
Xcode 4指南 – pipe理项目的版本
我打赌你正在尝试使用setValuesForKeysWithDictionary:来填充你的TaskViewController setValuesForKeysWithDictionary:或者类似的东西，而projectToolBar在视图控制器的头文件中不是一个有效的projectToolBar 。
也可能是@MatthiasBauch说的。
添加几个对象到故事板上的UITableViewCell后，我有同样的错误。 在此之前，该应用程序是完美的工作。
我能够通过去Xcode>首选项>位置>派生数据，解决这个问题，打开目录，并删除与应用程序的名称的文件夹。
希望我的评论会对稍后来这里的人有所帮助。
