Debugging a memory increase, using Generational Analysis

November 19th, 2013 Posted by: - posted under:Articles » Tutorials - 5 Comments

I was recently working on an internal project for Burnside Digital, and decided it was time to do some memory profiling to make sure that I didn’t have any leaks. I ran the program with the ‘Leaks’ tool of instruments, and as I was watching the Live Bytes column, I saw the number of Bytes being used, slowly but surely increasing as time went on. Instruments wasn’t detecting any leaks, so I knew this wasn’t going to be a straightforward leak …

Recently here at ELC, we’ve been working on an app that requires a lot of server interaction, which has been a learning experience for managing threading, server load and connectivity.

As I mature as a developer, I try to rely on other people’s code more an more. Why build something from scratch when a solution already exists that you can fit in your project. In Pocket MUD Pro, I used 13 3rd party libraries and am using quite a bit more in the project that I’m currently working on.

August 8th, 2012 Posted by: - posted under:Articles » Tutorials - 1 Comment

In this blog post I will demonstrate how to mock HTTP requests using an Objective-C runtime dynamic method replacement technique known as method swizzling. I will show how this can be used in tandem with some unit test technologies to help with development of iOS web-service client side code.

May 29th, 2012 Posted by: - posted under:Articles - Comments Off

I have just updated my MUD client [Pocket MUD Pro] to be a universal library. It was surprisingly easy to add the iPad support as most of the application was comprised of UITableViews.
The main “MUD” view was the most challenging part as it contains a couple UIWebViews, UIButons, and a UITextField. However, I chose to do something I feel is pretty cool.
