Friday Q&A 2014-05-09: When an Autorelease Isn't at 2014-05-09 13:59
Welcome back to another Friday Q&A. I apologize for the unannounced hiatus in posts. It's not due to anything interesting, just a shortage of time. Friday Q&A will continue, and I will continue to aim for my regular biweekly postings. For today's article, I have a little story about an
autoreleasecall that didn't do what it was supposed to do.
Friday Q&A 2012-06-01: A Tour of PLWeakCompatibility: Part II at 2012-06-01 13:38
Last time, I discussed the basics of PLWeakCompatibility in terms of the motivation, the basic hooks used to get the compiler to call our code when handling
__weakvariables, and calling through to the original implementations where available. Today, I'm going to discuss the implementation of the zeroing weak reference facility that gets used when the runtime doesn't supply its own
Friday Q&A 2012-05-18: A Tour of PLWeakCompatibility: Part I at 2012-05-18 16:53
A few weeks ago, I introduced
PLWeakCompatibility. This is a small library that can be dropped into an app to enable use of the
__weakqualifier on OSes that don't support it. ARC is officially supported on Mac OS X 10.6 and iOS 4, but
__weakis only available on 10.7 and iOS 5.
PLWeakCompatibilityadds support for
__weakon those older OSes when using ARC. Today I'm going to discuss how
PLWeakCompatibilityworks on the inside.
Introducing PLWeakCompatibility at 2012-03-31 03:09
As a way of atoning for the lack of a Friday Q&A today, I'm pleased to introduce PLWeakCompatibility. Do you like ARC? Do you need to support older OS releases? Do you wish you could use
__weakvariables on those older OSes? If so, then I have good news for you! PLWeakCompatibility is the solution you've been looking for.

Friday Q&A 2011-09-30: Automatic Reference Counting at 2011-09-30 15:02
Since the moment Apple announced it, readers have asked me to write about Automatic Reference Counting, or ARC. Today is the day. I'll talk about Apple's new memory management system, how it works, and how to get the most out of it.
