I need to store references to local files in CoreData. What is the best solution for this. Just now I use plain paths but there has to be a better way.


  I use the much-lauded BDAlias:

http://eschatologist.net/bDistributed.com/index.html

I encode it as data and store it that way. Using a transformable type as Dirkjan suggested, you can make it as convenient as -URL - setURL: and handle the conversion that way.

  URL <--> BDAlias <--> NSData

This way, you're referencing the file by its ID, not its location. If the location changes, your app still knows where it's at (unless it is removed from its original volume).
