LLVM Module Maps to the rescue!

I recently wrote about Cocoa / Cocoa Touch frameworks, and in writing about it I was sorely tempted to dive into Modules, since they are pretty important to modern frameworks. But it was such a huge topic, I decided to break it out into a separate post. In a nutshell, LLVM Module Maps were invented … Continue reading LLVM Module Maps to the rescue!

Logging with CocoaLumberjack and TestFlight

Consider the following situation that happens far too often in mobile app development: You've just released an app that works perfectly for you, and you've tested it extensively. You're proud of your accomplishments and submit the app to the world, only to have several emails sent to you from users who have nothing but difficulties … Continue reading Logging with CocoaLumberjack and TestFlight

Core Graphics is not only a C-only API, but has confusing function names, and needs way more code to do the same thing I can do in less code … Continue reading Core Graphics isn’t scary, honest!

Building a static library with Jenkins

One of my pet peeves is Open Source iOS libraries distributed as just a collection of Objective-C classes, rather than being bundled as a static library. I know a lot of people prefer it that way, but from a maintainability standpoint it really doesn't make much sense to me. So when I'm faced with another … Continue reading Building a static library with Jenkins

Using GCD and Blocks Effectively

With iOS 4.0 Apple introduced two new technologies to the iOS platform: Grand Central Dispatch, and blocks.  Simply put, it is to multi-threaded programming what fire is to a barbecue.  Sure you can do without it, but the end result is much better. Despite all this, developers still seem to avoid using it. Some of … Continue reading Using GCD and Blocks Effectively

Back to Basics: Using KVO

One of the things I like most about Apple's iOS SDK is the consistent and easy-to-use API they provide.  Across all their different frameworks there's a pattern at work that makes using their classes easy to understand.  This is due in part to the simplicity for configuring those objects.  In most cases you don't need … Continue reading Back to Basics: Using KVO
