'NSUnknownKeyException': this class is not key value coding-compliant for the key

I got this message:

*** Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<FirstViewController 0x601b610> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key newCell.'

How do I solve it?

In case that helps someone else, after checking and updating all your links between the views and the matching IBOulet, Cleaning you project can sometimes fix this issue.

That is generally due to deleting an IB object but forgetting to delete it's links.

IE deleting a UIScrollView but forgetting to delete how it used to link into UIView through an IBOutlet.

Had the same problem earlier today... found the answer here: http://www.iphonedevsdk.com/forum/iphone-sdk-development/47036-setvalue-forundefinedkey-class-not-key-value-coding-compliant-key.html
