Right before you call reload data log the current thread [NSThread
currentThread];
If it says anything other than main that's the issue. It happens all the time
since it's easy to forget that whatever callback tells you about the added data
ends up coming in on the background.
Hope that helps,
Dave,
Unfortunately on the OS X side with iCloud, Core Data, and documents it is
pretty much a pick any two situation. The iOS side can be done but there are
some gotchas not really covered in the documentation. I've actually just
started work on my own custom subclasses of UIManagedDocument
Tom,
The data store doesn't have a copy of the model in it, it just has hashes that
are used to quickly compare the store to the data model trying to open it. In
order for migration to work you will need to have both the old and new data
models. In lightweight migrations Core Data uses the two

I've only made a custom subclass of NSArrayController once and that was a long
time a go to do some custom thing that I don't remember now.
Normally I add an array to the appropriate view controller that has the table
data in it and then bind the NSArrayController's content to that array.
mparchet,
Let Core Data do the heavy lifting for you, that is what it is there for.
If you use an array controller with your UI and set up bindings you can get
away with out writing any code to make the base of your UI work.
If I remember correctly you can send your own SQL queries but you can
I have a UIDocument with a single property, an NSAttributedString, that I am
trying to save. The documentation says that NSAttributedString conforms to the
NSCoding protocol so I'm using NSData *docData = [NSKeyedArchiver

April,
You should try saving a non-iCloud document and see if you still have issues.
If so try going through a couple of Apple's basic Mac OS X tutorials to see if
they fill in the holes for you. If you are working with Core Data you can check
out some tutorials I've written for a document
First off I will echo what a few others have said already and I'm sure a
moderator will say fairly soon; this list is for the discussion of the Cocoa
and Cocoa Touch APIs not the tools commonly used to develop using said APIs.
There are forums and an Xcode users list that are appropriate for

It looks like you have an NSManagedObject that is observing itself. If this is
in fact the case what is the objective? There may be a better way to accomplish
your goal if you let us know what it is.

It seems there are questions periodically about printing table data that pop
up, so here is a class that takes care of a lot of the grunt work, MSTablePrint.

Amy,
A few things with what you are trying to do. First off, using IBOutlet for
array controllers is totally correct, basically any element you add in IB you
should access through an IBOutlet. As for the calculation of the a value based
on other values in Core Data you have a few problems. The
So I am working on a simple Core Data app that can track how much I
have made from various apps I sell (right now I just have two iPhone
ones I charge for). This is also the app that my Expenses tutorial is
based on. I am working on the monthly totals portion again and trying
to use
I just posted the third part of my Core Data tutorial dealing with
user preferences. The series also deals with bindings a good deal.

So I am looking for a better way to fetch all entities from each month
of the year so that I can get a total for each month.
Each entity has a date, amount, type (which is a to one
relationship to a type entity, the reverse is to-many). In the end I
want to break things down so that the

fine

Yes thank you both that has been driving me crazy mostly because I
knew it was something stupid like that.
Thank you,

Perhaps someone else has seen this before but it makes no sense to me.
The included code is from a NSManagedObject subclass and is part of a
method to return a readonly property that is based on the value of two
attributes (amount frequency).
With the this code: (I removed irrelevant code
