I've made my first foray into multitasking with Cocoa and am experiencing a
little snag that I was hoping someone could help me with. I read the
Concurrency Programming Guide (it was in one sitting, so my eyes probably
glazed over a few times) and decided to try NSOperationQueue. First I queued

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.

Well, I was imprecise. I didn’t literally mean the text view would directly
change the table view. Right now the text container and text view adjust
automatically to fit the text, but my code isn’t told about any changes, so I
have no opportunity to do anything to change the table view.
But o
You need to have the document content in order to test the password, right?
This might be naive, but could you load the document into an offstage memory
structure (meaning, don’t plug it into the user interface yet so the user
cannot see or modify it) and ask for the password only after the load

Hi,
I have an iOS8 app that uses the native iOS WebRTC libraries and therefore must
be armv7 or armv7s (as they haven’t got an arm64 build). I’m using PushKit for
VoIP notifications and while this works great on 32 bit devices, when we move
to test it out on a 64bit device it crashes with this

I wonder if anybody can tell me what I might be doing wrong. I used layout
constraints in InterfaceBuilder to define the layout for a UITableView
cell. The cell renders correctly, but I get a warning for each cell
displayed that contains a reference to a "FittingSizeHTarget" constraint

Hello Leonardo,
You are correct that your dirty workaround is not very good, since it won't
handle many cases. Since the typesetter inserts a hyphen glyph into the glyph
stream whenever hyphenation occurs, perhaps you should check for the presence
of that glyph at the end of each line fragment
A correction:

I forgot that NSTypesetter itself does not actually implement this method, so

I need to scale an NSImage's dimensions to exactly 640x480 pixels before

NSImage into an NSData for transfer, that resize information se

The size of an NSImage is an abstract property that does not reflect the pixel
dimensions of the representations within it. This sounds a bit odd, until you
realise that images can have any resolutio
