In the WWDC 2013 video about Core Data performance, they used an Earthquake
app. But this one is nicer than the threaded Core Data sample code. The sample
you can get uses none of the optimizations shown in the WWDC 2013 talk.
Is that Earthquake sample available anywhere?

Yes, my solution is to put all the items in a simple menu without submenus
and indent the subitems, as we can see here

Easy, simple, it works. Thank you for your suggestions. They drove me he
I've realized that my understanding of ARC is not as good as I thought it was.
So I'll be asking couple of questions.
With ARC I don't understand why autorelease pools are needed anymore except for
with objects passed by reference. What I mean by that is that class methods
like:

Hey guys,
I have a serious problem with the CollectionView and I don’t understand its
behavior.
My Project has a Splitview into 2 Views, one is a Scrollview with a
CollectionView the one is a normal NSView with background image.
The other one with the CollectionView has multiple items with own

I have an NSTableView with several columns bound to an NSArrayController
which manages the array of my custom objects.
Undo of course works while editing a cell in the NSTableView, but once the
edit is complete, I need to manage it myself.
How is the best way to do this?
I need to know the origi

For backward compatibility. Nearly every piece of existing Cocoa code uses
these methods, so there's no way they could take them out.

Because if they returned an object that wasn't autoreleased (i.e. that the

It's needed when a method creates an object [or otherwise gets an object with a
reference that needs to be released] and has to return that object, but the
And would be just like every other manual reference-counting scheme, with all
of the additional code they entail, and the higher liklihood of bugs, and so

One way to handle this is illustrated in Hillegasse's classic book on Cocoa.

Don’t. Use Core Data. Core Data will do it.

Remove the period between "Don't" and "Use", and your sentence is
correct.
Core Data isn't a solution. Removing bindings is the solution.
