I have a problem. I am making a very simple app in Objective C and Xcode keeps giving me an error that says Thread 1: SIGABRT. This is what the console says:
2013-12-27 20:01:24.375 RMF[1568:a0b] * Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[ setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key Main_menu_rmf.'
