Hey guys,

I was wondering how to convert a NavigationController style app into a TabBarcontroller style app. I changed my mainwindow to not contain a navigationcontroller anymore (but a tabbarcontroller instead) and my delegate also appropiatly, but when I launch the app something still thinks I want a navigationController:

Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[ setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key navigationController.'

Stack trace:

Where can I specify the app is a tabbarcontrolled app, instead of a navigationbarcontrolled app?

Thanks in advance,
