In a post today in the Developer Forums [1], developer Romain Piveteau
mentioned in discussing another topic that, in a Core Data app, he “can not
disable journaling mode” (by which I presume he means that setting the
journaling mode to the legacy “rollback” mode [2] is ineffective) when the u
I am trying to display font information on the user interface of my

Fonts with names prefixed with a "." or "%" are hidden from the higher-level
APIs for listing fonts.
I have a model object with a codeURL property which is readwrite and is an
NSURL.
I have an NSTextField in the NSView subclass with the value bound to the
codeURL property with a custom transform which turns a URL into a string (and
deals with nil and another edge case).
The transform is rev
... and I tried expressing the URL as an NSString property too, with no
transform. Similarly calling [ textField setStringValue: ]
didn't cause the setter in the model object to be invoked. That surprised me, I
thought binding an NSTextField to an NSString in the model object would be a

How are you setting up the binding? Normally you bind to the value property of
the NSTextField (not stringValue). See Cocoa Bindings Reference (NSTextField
Bindings).

Ah, interesting to know that, thanks Jens.
Yes, I guess I could leave it unchecked. But also my files are used
cross-platform, so I would prefer to store font information for standard fonts,
so will probably do the translation to standard fonts during pasting anyway.

Yes I've bound to the value property in IB. That gets the value from the model
object into my NSTextField perfectly via the transformer. It reads the
underlying NSURL property which it's bound to, applies the transformer, and
sets the text into the NSTextField (presumably by setting the stringVa
.. right so if I actually edit the NSTextField on-screen (it wasn't editable
before, I made it so) *THEN* the binding gets called in the way I expected.
So it would seem that only a user-initiated change of the value fires the
binding in reverse (which is what the example binding code in the Ap

That actually makes a lot of sense. It’s quite p
Hi, I am trying to use CTFontDescriptorMatchFontDescriptorsWithProgressHandler
to download a font. It appears to download fine, and I can display it in my
application. [UIFont familyNames] includes that font.
I restart my application, and [UIFont familyNames] does not include the
downloaded fon
