Can anyone tell me whether there are any plug-ins or examples that show how to implement buttons to move forward and backward through a record set in a Core Data application? I am thinking of having a window that simply presents one record from a collection, with forward, backward, first and last buttons.
This isn't really a "Core Data" question, but rather a bindings question.
Read up on Cocoa Bindings and NSArrayController. All you need to do is modify the selection as desired when these buttons are pressed via - [NSArrayController setSelectionIndex:] or -[NSArrayController setSelectionIndexes:], keeping in mind the array controller's - arrangedObjects (and the count thereof).
If the rest of your detail view is bound to this array controller's selectedObjects.whateverKeys, you're done.
