'NSUnknownKeyException'

I try to do very simple application for ios. Switching between viewes. And when it started this error in log:

Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<UIApplication 0x712d520> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key goToAuthorizeView.'
*** First throw call stack:

just go to iOS Simulator > Reset Content and Setting. clean and run your app. it will work.

It looks like you have some kind of control (Most likely a UIButton) defined in the XIB that a phantom connection exists to. Check your XIB and make sure that any outlet named goToAuthorizeView are disconnected.

When the NIB un-archiver defrosts your UI, it starts calling -setValue:ForKey on the elements defined in the archive. When it comes across an undefined key, or value, it throws a generic exception, because it's not safe to set a random undefined space of memory to a new value.
