Last week, I talked about Networking using NSURLConnection. In a future post, I’m going to talk about how to use AFNetworking. But first, I wanted to talk about why you should trust AFNetworking as a project in your project. I haven’t been using github for long. That said, AFNetworking is the best-managed git project I’ve […]
In the past, I’ve talked about Using blocks to remove redundancy. But now I want to explain the pattern I’ve adopted since, which is my favorite block pattern of all. Even though it, too, is all about removing redundancy: handling errors. Although Objective-C supports exceptions, they’re not commonly used. A thrown exception is usually not […]
In a previous article, I mentioned how to handle 302/303 redirects to web services. But that’s a fairly advanced topic, and we should have built up to that. What I’m going to cover: The basics of networking using NSURLConnection, part of Apple’s Foundation framework. What I’m not going to cover: How to determine if a […]
So you’re writing your first iPhone app. Welcome! But which version of iOS should you target? This is pretty simple. There’s very little reason not to write for iOS 5.0.
If you’re an application developer: Yes, you should use Automatic Reference Counting (ARC).

My application includes some XML files that are used while running to map data from a web service. This has drastically simplified the code I needed to write to parse data from the web service, since I can describe how to decode all of the types of object the web service interacts with simply. If […]
Who I am is the sum of many parts. More than my mind wants me to believe. There’s a part of me that’s capable of problem solving, of creativity, of insight. My mind is the part of me that questions things. It’s my inner critic. It does most of the talking in my head. Mostly, […]
In the recent past, I’ve mocked Xcode’s snapshots. They were sluggish and not especially reliable. I’d like to say they were inefficient, too, but the truth is that they were so slow and so unreliable I never bothered to find out. Recent versions of Xcode have been a lot better. I’m not sure when archives […]
All models of iPhone since the 3G, as well as the iPad 3G and iPad 2 3G, include Assisted GPS (AGPS). I’ve heard that this isn’t real GPS or that it’s somehow inferior to real GPS. AGPS is actually superior to “real” GPS. However, there are ways the iPhone is also inferior to a standalone […]
