My App Store release checklist

For the longest time it seemed that releasing an update to an iOS app was a random whack-a-mole process that I’d invariably get wrong in some way.  It was maddening, especially since iTunes Connect has only recently become a decent web application.  By switching to Jenkins for continuous integration of my iOS app builds I’ve […]

Docset Viewer: Resuming large downloads with NSURLConnection

As I’ve shown in my previous post announcing Docset Viewer, I want this series of posts to be more than me talking about my new app. In keeping with the instructional nature of my site, I’m going to show you a few things that I did in my new app Docset Viewer and how I […]

Core Graphics isn’t scary, honest!

For anyone who’s developed exclusively with UIViews on iOS may take the title of this post a bit oddly. “WHAT?!” they might say, “Are you insane? 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 […]

Back To Basics: Simple debugging tips in Xcode

As developers we spend most of our lives dealing with broken and barely-functional software: our own software. We do our best to make the applications we develop somewhat less broken and try to add features to make it functional. And once we finally get our software working bug-free and functioning stably, what do we do? […]

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 […]

So for this entry in my “Back To Basics” series I’d like to talk about UITableViews, and how to simply and easily construct one without convoluted or confusing code. […]

Back To Basics: Positioning UIViews

These days I’ve been working on some fairly advanced iOS development techniques on my various projects: I’ve taught myself (badly) about Core Audio, I’m learning OpenGL, I’m developing a series of applications using Core Data, asynchronous parsing of JSON from a streaming HTTP connection, etc. It’s extremely fun and easy once you understand the basics. What I […]

Smarter and More Reusable Core Data

Like most developers, I look to Apple’s default application templates to get up-to-speed on what would appear as being the Right Way™ of developing apps on iOS. In practice however what you need to realize is Apple’s templates are meant to be the easiest introduction to a set of tools that can be fairly complicated […]

Building iOS apps for Over-The-Air AdHoc distribution

I’ve written about building iOS applications with Hudson Jenkins, but until recently there hasn’t been a convenient way of getting those applications to your testers. Of course the most important part of your build output will be the app bundle you send to Apple’s iTunes Connect web interface, but throughout your development cycle you’ll want […]

Animating Interfaces with Core Animation: Part 4

This is the fourth in a series of posts I’m writing on animating iOS interfaces using Core Animation. In the first post I created a planetary orbit demo using nested CALayer objects. The second post showed how to dress up a UI by animating an image. The third post shows how you can trigger animations […]
