I have an instance of NSSlider that I've marked as "continuous", but I also
need to know when the user has released the mouse button and stopped messing
with the slider. Do I need to subclass NSSlider and override mouseUp:, or is
there a better way?

Thank you Joanna, that was very helpful. So, from your experience,

object, just editing an existing one? It seems like the real pain point is
having to re-create the new object in the second managedObjectContext and copy

folder,
c. Sav
Thanks Paul - good to know what the error message means. The only file in that

When you do a save as, it appears that the steps core data follows are
different than when it does the first save as. I have a simple project where I

Hi Kirk,
The variable wildcardString would contain a string such as *GREEN* for a
wildcard search to include files with that name, and for simplicity's sake a
string like !*GREEN* for those that wish to exclude files that contain the
string.
Here is a sample bit of code..
BOOL foundStar = NO;
Hmm, now I am confused because I just checked the docs for NSOperationQueue and
it says:

Returns the maximum number of concurrent operations that the receiver can
execute.

You were correct, I had not altered the queue to something other than
the default. After reviewing the docs, i found this ...
If you specify the value
NSOperationQueueDefaultMaxConcurrentOperationCount (which is
recommended), the maximum number of operations can change
dynamical
And thank you for the NSURLConnection suggestion. It's always good to have
alternatives. :)

You can always slide the search field into the window, below the navigation
bar, while pushing (or, perhaps, vertically resizing) the table view. If you
set the auto-resizing properties of the table view correctly, more than half of
the work is already done. The only remaining question is one of
I suggest that you need to provide the actual code you are using to generate
the NSPredicate, because what you are wanting to do just isn't that hard.
The problem may not be in the predicate format string.
I would have used @"NOT CONTAINS[cd] %@" as my first pass, and been quite
surprised if i
hmmm to be honest, I am not sure ... there is a possibility that i did

I will look into this and THANK YOU for the insight.

It was serial? Did you, by any chance, set the maximum number of running
operations to 1? I don't recall for sure now, but that may be the default,
actually. As far as I know, independent NSOperations in the same queue are
executed in parallel, subjected to resource constraints and the maximum n
NSURLConnection was indeed more appropriate for what I needed, and what I ended
up using.

Just to be clear, it works great for me off the main thread. The problem I have
is when I have multiple CoreImage operations on separate threads.

Hi all!
Okay, I've mostly finished my (in-house-only) corporate phone-book

My app is a navigation-based application with a single UITableView

on top, so there's no room to put a search f
NSURLConnection does this as well. The main issue i had with using an
NSOperation/OperationQueue was that is was "serial" ... using the
NSURLConnection allowed me to handle MULTIPLE asynchronous downloads

You can also do:
#if !defined( NDEBUG )
/* Debugging Stuff Goes Here *.

I don't have an Xcode install handy to actually check (I'm

builds, and not defined for debug builds.
The reason is that the assert macro in d

I have found and fixed the problem with getting two extra objects instead of
one, and have gone through all my code yet again, and I think I am down to 2
issues:
1. When I do a save, then Save As, then Save As again, I get a message that one
of my objects has been invalidated. I haven't edited
You don't need to overcomplicate downloading the images with an
NSOperation.
In my experience, downloading asynchronously with an NSURLConnection
and the delegate methods works far better.

In my experience, CoreImage is not thread safe. I could probably dig up the
details if necessary, but the gist is that we were experiencing
CoreImage-related crashes when running off the main thread. Moving to the main
thread fixed the crashes.
Unfortunately, I'm not aware of any documentation
Thanks for the suggestion!
All of the examples I gave work if you are trying to match the
argument. CONTAINS is another way to match, but will it work with NOT?
So far, everything that you would expect to work, doesn't. This is a
case where you wish that Apple would document this better. (I

Hi Everyone,
You would think this is simple, but I can't figure this out.
Lets say I have a pile of NSString Paths in an array, where some of them have

I've been trying to build an NSPredicate which would exclude elements that
contain the name..
