You could make your objects subclasses of NSTreeNode, and use its

From the docs it sounds pretty standard:

strange - but fair enough.

It appears that items in the TemporaryItems folder that are older than 3 days
will be periodically deleted. (One of our guys found some Darwin docs that
mention this.) This is a problem for users of our app that might keep it
running for more than 3 days. We store a temp folder in there that mig

I’d love to, except that background threads don’t correspond to dispatch
queues. People who are [still] using NSThreads should be able to use this
library.

Is there a way to tell whether the current thread has an active runloop?
I ask because the library that I develop will internally call
-performSelector:withObject:afterDelay to schedule an action at a later time.
The library can be used on a background thread, with some caveats. A couple of

Yes, if you’ve got a custom data model, then you’ll need to write custom code
to navigate it with an index-path.
NSArrays-of-NSArrays aren’t really in common use in Cocoa, so they count as a
custom data model IM
If all you have is a nested set of arrays, then you¹ll have to write your
own objectAtIndexPath: method that walks your nested set of arrays.

Going through a NSTreeController feels like cracking a nut with a sledge-hammer.
Then I would rather roll my own.
There is really no other way?

First you need a NSTreeController to manage your NSArray, then:
NSTreeNode *topNode = [treeController arrangedObjects];
return [topNode descendantNodeAtIndexPath:indexPath];

The Apple docs state:
"The NSIndexPath class represents the path to a specific node in a
tree of nested array collections"
I can't find how to use the index path to access the tree though.
It should be something along the lines of:
NSIndexPath *indexPath = ...
NSArray *nestedArrays = ...

Finally it works!
I now have a CALayer backed UIView with CATiledLayer sublayers with full
zooming support.
I'm not entirely sure what change actually turned it into something
working, but I'm happy it does work now.
Thanks for all support.

I'm pretty sure the answer here is no. I can think of nothing which exposes
that session key, I can believe that it's something an API would not lightly
expose and I do wonder what you could possibly need it for, especially on iOS,
I can almost think of ways to use it on OSX, almost, but on iOS

I am trying to get the session key of an existing, working and tested

I have a series of CALayers which are all siblings within a hosting layer. I

Problem is that the shadow draws behind all of the sibling layers.
So, I tried setting the zPosition of the shadowed layer so that it's well 'in
