Re: finder eject images
As everyone else has been saying, NSWorkspace image for
type/file APIs and +[NSImage imageNamed:] are the API, and if it isn't
there, you can file a bug but should use your own artwork. (As it says in
the NSImage header.)
Even if it isn't available via imageNamed, you might still be able to find it
by using IconServices.
That contains a lot more icons (lots of which are long obsolete)
See IconsCore.h. I'm not sure how you'd go about converting an IconRef to an
NSImage, but maybe you don't need to. You can just draw them directly using
PlotIconRefInContext.

True, but this method has been working for our app for 8 years now, no
problems :)
If you have any better suggestions, feel free to let me know!
You know, people really like to use this excuse. And then when it stops
working, they're like it's been working for so long!
This is not part of the API, and it is not supported. Not every piece of
artwork the OS uses can be considered supported API - we'd never be able to
change anything. As everyone else has been saying, NSWorkspace image for

movieViewer is a QTMovieViewer outlet inside the new window.
In addition to Kyle's observations, I would also point out that your method of
checking for failure in +[QTMovie movieWithFile:error:] is incorrect. The
primary check for failure is the return value (did it return nil?). Only if it
returns nil should you then pay any attention to the error value.
QTMovie *movie = [QTMovie movieWithFile:moviePath error:error];
if (movie == nil) {

Re: Animating a flickering display

However, I end up in a cycle, whereby the call to [NSBundle loadNibNamed:name
owner:self] generates a (unexpected) callback to -awakeFromNib. How come? Is
this normal behavior?
This is not the case if I substitute nil to self in [NSBundle loadNibNamed:name

The NIB's owner is effectively an object in the NIB, via the File's Owner

Re: Delay in reading cookie using NSHttpCookieStorage
I don’t think the cookie storage is guaranteed to be 100% in sync across apps all the time. WebKit is probably batching up changes in memory before writing them out to disk. You should probably find a different way to do what you’re doing. Also, launching an applet to launch your app seems cumbersome — the usual way to have the browser launch a custom app is to make up a custom URL scheme, register the app as handling that scheme, and then have the browser navigate to a URL of that scheme. This has the advantage that you can pass information to the app in that URL (which might remove your need to read the cookie?) —Jens___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

That looks right to me (assuming the third line's owner: is a typo). Though as
Jens Alfke says, if you make your owner object a subclass of
NS{View,Window}Controller it will take care of some housekeeping for you.
In what way is it not working as expected? Are you checking the results of
loadNibNamed:, etc? Are your owner object's outlets being set to the correct
non-nil objects instantiated from the nib?

Core Data Predicate Question
Hi all,
I have a Core Data object model that I'm trying to write a fetch predicate for
(to use for search). Quick explanation of the model:
We'll call the main entity Book. There's also a Keyword entity. The Book
entity has a to-many relationship with the Keyword entity called keywords. In
turn, the Keyword entity has an inverse relationship with the Book entity
called book. The Keyword entity has a single attribute called name. So
basically, each Book has Keywords that describe it.
For my search, I have an array of search terms. I need a predicate that I can
use on fetch requests for the Book entity that will evaluate to TRUE if ALL of
the search terms have a corresponding Keyword in that the name property
begins with the search term.
For example:
There are three books:
Book1 - keywords: {fiction, scifi}
Book2 - keywords: {nonfiction}
If the search terms were {fic, nonfic, sci} the resulting fetched array
would contain NOTHING because none of the books have keywords that begin with
all 3 of those search terms..
However, if the search terms were {fic, sci}, the resulting fetched array
would contain Book1 since its keywords fiction and scifi begin with the two
search terms fic and sci. The key part here is that ALL of the search
terms have to have a corresponding keyword as demonstrated above for the
predicate to evaluate to true.
I hope I've explained this problem well enough, it's hard to put this stuff
into words ;-)
Any help is appreciated,

I've been through the documentation and I can't find anything new about how this works. Is there any documentation how we implement Auto Save and Versions? Is the the same old autosave functionality that's been around for a while? Second question, I have a Core Data document-based app so I've been running under the assumption that it's not recommended use Auto Save. This may be urban legend. If it's real does it still apply?

What is returned from CFLocaleGetSystem?
When attempting to use CFLocaleGetSystem() as a parameter to
CFDateFormatterCreate(), a call to
CFDateFormatterGetAbsoluteTimeFromString() using the created
CFDateFormatterRef seemed to always return false. However, when I changed
the code to use a locale created by CFLocaleCopyCurrent, formatting was
successful. See my static C++ function below:
GregorianDate GregorianDate::getFromFormat(
const ReferenceCountedNonMutableString date, const
ReferenceCountedNonMutableString format) {
CFAbsoluteTime absTime;
CFGregorianDate gregDate;
CFLocaleRef locale = CFLocaleGetSystem(); // or
CFLocaleCopyCurrent();
CFDateFormatterRef dateFormatter = CFDateFormatterCreate(
kCFAllocatorDefault, locale, kCFDateFormatterNoStyle,
kCFDateFormatterNoStyle);
CFDateFormatterSetFormat(dateFormatter, format.getAsCFStringRef());
CFDateFormatterSetProperty(dateFormatter,kCFDateFormatterIsLenient,
kCFBooleanTrue);
Boolean success =
CFDateFormatterGetAbsoluteTimeFromString(dateFormatter,
date.getAsCFStringRef(), NULL, absTime);
// return an invalid date
if (!success)
{
return GregorianDate(0,0,0);
}
gregDate = CFAbsoluteTimeGetGregorianDate(absTime, NULL);
CFRelease(dateFormatter);
// CFRelease(locale);
return GregorianDate(gregDate);
}
The documentation states CFLocaleGetSystem returns the root, canonical
locale, which contains fixed backstop settings for all locale
information. Clearly, this appears to be something different from the
current user locale. My question is: is this a valid locale for anything?
What is its use-case?
Thanks in advance!
Mark

Re: Dynamically loading NIB files with a common stem
Le 6 juil. 2011 à 18:10, Douglas Davidson a écrit : It isn't necessary to use @. here; you should be able to pass nil for that argument if the resources in question are not in a subdirectory. From the header comments: subpath is a relative path to a subdirectory inside the relevant global or localized resource directory, and should be nil if the resource file in question is not in a subdirectory. Yes, you're right. It works like a charm. I am a bit lazy, I never consider digging into the header files to get some hints. For me, all the help available is (and maybe should be) in the documentation… Thanks a lot everybody for your help!
