This class is not key value coding-compliant for the key


#1

Hi!
I just completed the first chapter of the book and wrote all the necessary code.
Since I’m using Xcode5 I deleted the storyboard and aded the xib file. Then, in the Info
properties of the project I change the variable “Main storyboard file base name” to
"Main nib file base name" and set the value to the name of my xib file. Later, in
the File’s Owner I set the custom class to QuizViewController and made all the connections.
I don’t have any compilation errors but when I execute the project i get the following error

2014-01-20 12:37:17.872 Quiz[1616:70b] *** Terminating app due to uncaught exception ‘NSUnknownKeyException’, reason: ‘[<UIApplication 0x8d525e0> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key campoPreguntas.’

Any help is appreciated.
Thanks.
