Unrecognized Selector Sent to Instance UIViewController

Question

I keep getting the error:

NSInvalidArgumentException\', reason: \'-[UIViewController setPhotoCellName:]: unrecognized selector sent to instance

Answer 1

It sounds like you've accidentally got a plain vanilla UIViewController rather than a FlickrImageViewController. Maybe you forgot to assign the controller's class?

Answer 2

You believe that your destination is an object from the FlickrImageViewController but the app doesn't. Look at the class you have assigned that controller in your storyboard; according to the error, it's a bare UIViewController.
