Forcing a method to run on the main thread

You know how many times, as an iOS developer, you want to ensure some method or delegate call occurs on the main thread?  We do this dance countless times, and while it’s straight-forward enough, it can be a burden sometimes.

Here’s an easy way to keep your thread access safe, without having to write a lot of code in the process.

Don’t live to work…

Many people have heard the phrase “Don’t live to work; work to live”.  This usually means that the goal of working should be to enable you to live your life, rather than allowing work to consume your life.  Far too many people in the tech industry sacrifice their families, spouses, children, and even their sleep, in order to make it in this industry.

Docset Viewer update v1.5

The past year has been quite a ride, to say the least! I have been so busy with work, creating awesome features and technologies on iOS apps that over a year has raced by without an update to my blog!

I’ve also been neglecting my own apps due to being so overwhelmed with the requirements of my work as the lead developer for’s iOS Chatter app, so it wasn’t until recently that I updated Docset Viewer to add support for iOS 7.  I’ve adapted the design to fit more in line with iOS7, while still providing the same experience as before on iOS6 and earlier.

In addition to iOS 7, I’ve added support for full-screen mode in landscape on iPad, hiding the sidebar.  I also added search term highlighting in search results to make it easier to find the matching text you’re looking for. Continue reading “Docset Viewer update v1.5”

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 greatly improved my process, but things didn’t really improve until I created a checklist for keeping track of my releases.

Since I’ve been asked many times about this very topic recently – both at work and on Twitter – I thought I’d write a post about how I bring some sanity to my release process so my app updates are timely and predictable.

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 in running the app. You send a bug fix release to the App Store, but since you’re still unable to reproduce the problem you’re at the whim of luck and end-user feedback. You can hope your users know how to send you a crash report, but what if the app isn’t actually crashing? Wouldn’t it be great to be able to access your app’s log information from that client to be able to troubleshoot the problems?

Docset Viewer v1.2 and how to customize iCloud backups

I’ve recently released version 1.2 of Docset Viewer, which fixes a number of bugs people experienced with the previous version. If you had problems with the previous release, please give this one a try.

One of the improvements I’ve added is the ability to customize whether or not you would like to back up your Docsets (which can get quite large) into iCloud. To keep with the instructional nature of this site, I’ll show you how you can do that in your own apps.

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 put it together. This time around I’m going to show how I use NSURLConnection for downloading large files, and even resuming them.

In Docset Viewer I’ve added the ability to download docsets directly from Atom feeds, either from custom URLs or from a pre-configured list of Apple’s available docsets. Since you may not be consistently connected to the Internet, it’s important to be able to download documentation packages incrementally, especially since they can be anywhere from 300MB to 500MB.
