嘿，我无法弄清楚我遇到的错误.我的应用程序正常运行，但我不确定自己做了什么，但是现在无法打开，而是出现此错误:

Hey I can't figure out an error I got. I had my App working and then I'm not sure what I did but it won't open now and instead I get this error:

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.

Any Ideas what might be the problem? I can add my project code if I need to...

所以我看了一下，在界面生成器/故事板中，有一个指向projectToolBar的链接，该链接在头文件中没有对应的行.我删除了IB中的问题，但是，现在我遇到了一个新错误，但仍然无法正常工作.

So i looked and in the interface builder/storyboard there was a link to projectToolBar that didn't have a corresponding line in the header file. I deleted the problem in IB, however, now I am getting a new error and it still isn't working.

*** 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:

推荐答案

最有可能您拥有一个xib文件，其中包含一个仍连接到名为projectToolBar的(现在不存在)插座的toolBar.

Most likely you have a xib file that houses a toolBar that is still connected to a (now nonexistent) outlet named projectToolBar.

您从TaskViewController.h文件中删除了IBOutlet UIToolBar *projectToolBar;.

您应该考虑使用源代码管理管理，以便可以看到所做的事情. ;-) Xcode 4指南-管理项目的版本
