Unknown class in Interface Builder file.

[RyanW]

Hello,
I have an app I am working on, involving a TabBar app with a UITableView inside one of the views. When I run my app, in the console I get the error:

Unknown class MainNavController in Interface Builder file.

I have checked to make sure all my header files needed are imported, but this has not fixed the problem. Please let me know if you need to see any of my code. I have tried adding flags in the Project Settings, with no luck. Any ideas?

It sounds to me like at some point you created an object of type MainNavWhateverItWas in one of your nib files, and then renamed that class, or deleted it. Ar runtime, the system is trying to un-archive an object of that type, but can't find the code it needs to do so.

If you can't figure it out and want help from this forum you will probably have to post your entire project, since it's the interaction between ALL the classes in your project and all the nibfiles, AT RUNTIME, that is causing the problem.

EDIT: LOL! The auto-correction feature in 10.6 keeps changing "nibfiles" to "nibbles"!

Thanks for the reply. I would rather not post it all, and I will need to go through it and look at it all. Although the error says Interface Builder, should I be looking in the code, or IB itself?
Thanks
