Convert NIB to XIB without Builder Interface

Question

I upgraded to XCode 4 and because IB is now not in any of my old NIB files, you will open the error message "ASKNibConnector instance error cannot be decrypted." Is there a way to convert NIB to XIB without creating an interface? or do you need to do something like reinstall 3, convert feathers and reinstall 4?

Answer 1

To convert your nib to xib format, use the ibtool command-line ibtool as follows:

 ibtool foo.nib --upgrade --write foo.xib 

Or use this method to find all your nibs and convert them: https://gist.github.com/254161
