I hope this helps explain my problem better...Sorry for the confusion. The 'content' binding of your array controller should be bound to an NSUserDefaults object (labelled Shared Defaults by Interface Builder) with Controller Key = 'values' Model Key Path = keyToYourArrayInRootOfUserDefaults. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Storing a table view in user defaults
Hey, thanks! I actually ran across your code last night when I was first doing this. I ran your code and it worked fine. I created a test project to copy your code, and mine failed. I tried looking at every checkbox and every key path, nothing worked. I've uploaded my the test project to github. I'd love it if you guys could take a look, and tell me what I'm doing wrong. I feel like it's an exact copy, but it doesn't work. Hopefully this can provide an insight into my stupidity. http://github.com/ryanbriones/tableview-userdefaults If you don't have git, you can download a zip or tarball from the downloads tab. Thanks!

Storing a table view in user defaults

Seems like pretty standard setup from what I can tell. Yes, it is. Sorry to be picking nits but what you've described is very similar to what I have done. The answer is going to be in a nit. Add an item to your table, then gracefully quit your application. Open the file ~/Library/Preferences/com.myCompany.MyApp.plist with a plist editor and look at arrayOfThings. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Storing a table view in user defaults
You were right there. All you have to do to get it to work is check 'Handles content as compound value' on the array controller content array binding.
