Hey ever-so-helpful MR community, I'm back again trying to appease the bajillions of user requests I've gotten for my program, iProcrastinate. Two that I've been really trying to get to work but can't are splitviews and drag-and-drop support for NSTableView. SplitView: Where the heck is it? How exactly do I set up an NSSplitView? I was expecting there to be some nice looking dot on the IB palette you could drag to your app and wah-lah, splitview, but nope. I can't seem to find how to implement this class at all! (I think I just need a nudge in the right direction.) NSTableView: Everyone says adding drag/drop functionality to tables is easier than pie, then goes on for pages describing how to get it to work in your app. I've read through countless tutorials both third-party and from Apple, but can't seem to get the hang of things. I've got my tableviews being fed their data from a binding to a Core Data entity, and can't figure out how to assign that as my data type for the acceptable drag/drop action. Thank you guys so much for all your help in the past, present, and I'm sure future. It's people like you guys who make it so easy to make apps like mine free!
