Error: this class is not key value coding-compliant for the key projectToolBar? [duplicate]

Question

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.'

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

edit:

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.'

Answer 1

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

You removed IBOutlet UIToolBar *projectToolBar; from your TaskViewController.h file.
