Self-Destructing App

Hi,

I get an error when running the app after inserting IBAction implementation for Signup button in SignupViewController.m Actually, I get the same error if I delete all the code from IBAction implementation, which leads me to believe theres nothing wrong with the code itself, but something else behind the scenes.

It gives me this error: 2013-12-10 00:53:34.767 Ribbit[21639:70b] *** Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<SignupViewController 0x9e65c80> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key userNameField.' *** First throw call stack:

//lots of frameworks listed here (most probably all of them)

libc++abi.dylib: terminating with uncaught exception of type NSException (lldb)

How to fix this?

I figured it out :)

Previously I replaced userNameField with usernameField without erasing all the traces of previous connections so I had lingering connection that caused the error.

Im getting better at this :)

Even frustrating errors like that help you become a better developer! Glad you got it figured out. :)
