Weekly Roundup: Other Obsessions

by Aaron Brethorst | November 16, 2013

You might not know this about me, but when I'm not slinging Ruby or Objective-C code, I'm almost certain to have a camera in my hands. I try not to obsess about photography gear too much because a) what's behind the viewfinder is more important than what's immediately in front of it, and b) it can get very expensive very quickly. But, I'm certainly not immune to the allure of new stuff. Lately, my obsessions have been proceeding in two rather divergent directions: a new-found appreciation for film, and capturing motion in a still frame.

The second obsession is why I was excited recently to discover a Kickstarter campaign for gear that should make it incredibly easy to trigger your camera in response to external events, like a laser sensor being tripped, a sound above a certain decibel level occurring, or a bright flash appearing. As it happens, the Triggertrap Kickstarter campaign ended Saturday morning (which is the same time when I write these posts), and when I sat down to find an App of the Week, I was delighted to find the Triggertrap iOS app had been added to our list of apps.

The sheer number of open-source components, the rate at which new ones come in, and the unexpected places where these controls get used never ceases to amaze me.

Do your apps use components from Cocoa Controls? You should find the pages for the controls you use, click the Apps tab, and add a link back to your app on the App Store. I love featuring cool apps that make use of the site, and would love feature yours!

Best,
Aaron

p.s. I normally wouldn't engage in this kind of flagrant self-promotion, but I feel like I should share a macro photo I took last week that ended up being the 52nd most popular photo on Flickr the next day. Check it out, along with the setup shot.

BkTask

BkTask

An asynchronous workflow library for iOS inspired by the Proactor and Reactor design patterns. It is designed with two concepts in mind, asynchronous and modular.

Doing work asynchronously allows to keep your application responsive. But parallel programming is hard. On iOS, tools like GCD and NSOperation makes it much simpler but, for complex workflows it still takes time and resources to achieve. BkTask allows you to simply run workflows in background and be notified once it is done.

  • Allows both dependency injection (injection of classes defined in the DI context) as well as configuration management (values that get converted to the required type at runtime). Because this allows. . .

  • No fragmented qualifier macros, modules, etc. Makes it easy to have multiple configurations of the same base-class or protocol.

  • Supports both initializer and property injection. In the case of the latter, it has customizable call-backs to ensure that the class is in the required state before and after properties are set.

  • Lean. It has a very low footprint, so is appropriate for CPU and memory constrained devices.
