I think, your IBAction connection is missing with that button. Remove actions of those buttons and connect again.

Your two IBAction buttons :

  • userPressedOnUnlockFullVersion
  • userPressedRestore

Aren't correctly connected. So you must remove them by clicking on (x) And reconnect them. They must appear like the other IBAction buttons (black circle)

Your two IBActions userPressedOnUnlockFullVersion: and userPressedRestore: are not available anymore. You might have renamed or deleted them.

Verify your IBActions then remove those action connections from the interface builder and try to reconnect to buttons. It might have new IBActions.
