App is a simple 'test you knowledge' app.

This is what I keep getting:

Code:
2014-03-06 21:38:17.241 A2 Computing Quiz[1058:60b] *** Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<UIApplication 0x15d460f0> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key answerField.'
*** First throw call stack:

libc++abi.dylib: terminating with uncaught exception of type NSException
Not sure what's going on. Can supply additional code if needed. Thanks!

You did not supply any details or code.

We are programmers, not wizards :)
Oops. That was what was in the debug area at the time. Getting a different result now:

Yes, but you still have not provided any code. The first thing a person debugging this is going to want to do is: look at the code where this exception is occurring. So, please be considerate of those you seek help from and provide the code as well. Thank you.

Less lost in L.A.
My guess is that you have set up an instance variable and connected an IB item to it, then went and renamed the ivar. You have a disconnection between the interface file and its corresponding source file.

Click on the Files Owner and review the Outlets section for a connection to an outlet named answerField.
