Ok, if I had to guess your problem is a typo.

Take a look at the start.

*** Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[ setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key currenPerciptionalLable.' ***

See how you have spelt currenPerciptionallable

It is ok to spell things however you wish, but it is important that is spelt that way all through your code. At a guess you have misstyped a value someplace. Review your code, validate all of your value names and verify that you have no made any typo's. Xcode will help by highlighting most of them, but sometimes things are syntaxed in such a way that xCode wont understand that you have a typo at compile time.

So double check everything is typed correctly. :)
