Hello,
I'm having an issue where an NSTableView appears to be messaging its delegate
after the delegate has been deallocated, causing an EXC_BAD_ACCESS crash. It
doesn't always happen, but it happens regularly. My understanding is that
NSTableView's delegate is a zeroing weak reference, and so

Hi,
I’m having an issue where it appears that an Imported UTI for a certain file

for the same file extension declared by a second application. Everything I’ve

Good morning,
I’ve got a scenario where I need to prompt the user during reading of a
document in my OS X document-based application. There have been some minor
changes to the format of my document files, and I need to support opening
documents saved in the old format and prompting the user to

Good morning,
My document-based application can potentially display an app-modal dialog via
[NSApp runModalForWindow:] from within my override of [NSDocument
readFromURL:ofType:error:], in order to prompt the user for the password to
open a document. For the most part, this works just fine.

Ah, I see, I thought you were already *providing* a completion handler
somewhere, but I guess you’re not. In that case, I think you would override
-[NSDocumentController
openDocumentWithContentsOfURL:display:completionHandler:], like this:

Good morning,
I’m implementing a floating document inspector for my document-based app, and
am having trouble getting undo/redo working reliably when the inspector is the
key window. Specifically, NSWindowDelegate’s -windowWillReturnUndoManager:

I’m wondering if someone can provide some guidance or best practices on how I
might preserve actions on the undo/redo stack when the target of those actions
is deleted?
For example, say I have an application that allows me to add and remove records

Good morning,
Does anyone have any idea if there is a way to get the document architecture to

exclusive file lock at the filesystem level, as in no other user or process can
open, move, or delete the file. I’m not t
