So WWDC 2012 was announced at early o' clock and sold out in less than two hours. New restrictions on multiple purchases didn't do anything to stave the ever-shortening window. As compensation for all the interested developers who won't get to go to WWDC this year, Apple has promised to quickly post the session videos … Continue reading WWDC of the Future
Adding namespaces to Objective-C is a non-trivial problem. This proposal is a working draft; it may have bugs. (In particular, the definition of @namespace blocks and the @using directive is incomplete, but it's analogous enough to other languages that the intent should be obvious.) This draft will certainly need updates; I welcome comments at optshiftk … Continue reading Draft Proposal for Namespaces in Objective-C
Last Thursday I gave a talk at Seattle Xcoders titled "iCloud: Lessons Learned." I'm very grateful for the warm reception and the stunning turnout—there were over 40 attendees, many of whom asked some very good questions. By request, I have uploaded my slides. Hopefully they will be useful. If anyone happened to take video of … Continue reading Slides Available from “iCloud: Lessons Learned” Talk at Seattle Xcoders
**Update:** I just re-read a cocoa-dev post from last month in which Kevin Perry from Apple states the following: > I don't see the nested uses of performSynchronousFileAccessUsingBlock: you mentioned in that code, but that's not a problem anyway, since file access is recursive, as long as it happens synchronously within the outer-most file access block (a fact that admittedly may not be documented well anywhere). That would certainly change things. Perhaps the reason that -relinquishPresentedItemToWriter: was deadlocking on me is because it calls -performActivityWithSynchronousWaiting:, not just -performSynchronousFileAccess? I'll have to experiment. * * * **Now that iCloud** is out, I can finally talk about this in a public forum. Unfortunately, the cocoa-dev mailing list is down. But I really need to get this question out there, or at least written down, because it involves one of the most confusing new APIs in Lion: -[NSDocument performSynchronousFileAccess:] (or -performAsynchronousFileAccess: if you really hate your sanity).
I noticed that the Resource Programming Guide has been updated for ARC, which prompted me to investigate something that has puzzled me for a long time: how does NSWindowController interact with NSWindow's "convenience" method -isReleasedWhenClosed? It turns out that NSWindowController actually calls -setReleasedWhenClosed:NO on its window as part of -setWindow:. It doesn't matter if NSWindowController … Continue reading NSWindowController and -[NSWindow isReleasedWhenClosed]
After the President finished his speech announcing the death of Osama bin Laden, I bitched on Twitter about his citation of the Pledge of Allegiance, including the Cold War-era addition of “under God.” And I got a small bit of blowback for it. Rather than continue the complaint in 140-character pieces, I figured I’d do … Continue reading Why I Complained About “Under God”
