Here is some iOS code that allows you to generate your own terrain in a 2d iPhone side-scrolling style game by simply dragging your finger up and down. The possible potential uses are endless. This code uses Cocos2D.

Why game devs don’t use Objective-C
Published on August 22nd, 2010 in iPhone Code Snippets & Tutorials, iPhone ProgrammingAsk any developer of fast-paced iPhone games what language they use and none will say Objective-C. I am not referring to card games, or simple games like SpaceBubble. I am talking about processor intensive, special effects, things flying at you from all angles, kind of games. Of course every iPhone game has to use SOME Objective-C to get the app up and running and for certain API calls, but those kinds of things should not take up more than a few hundred lines of code at most in a large game.

iAd Profit, the truth
Published on August 19th, 2010 in iPhone ProgrammingWith the arrival of iAd came a way for developers to produce free apps and still pay the necessary development expenses. Some have seen huge success, but with questionable fill rates to see profit worth your time you will need an app with a steady 1,000+ a day download rate which is pretty hard to achieve in the App Store these days.
I will use iStrobe as an example. The first day of release saw about 35 downloads at $0.99 with a quick drop to about 3 downloads a day. Once I made it free I got a rush of about 2,000 downloads with fill rates on ads barely touching double digit percents.

iOS Core Location GPS Tutorial pt.1
Published on August 16th, 2010 in iPhone Code Snippets & Tutorials, iPhone ProgrammingCore Location is a powerful yet simple iOS framework allowing easy access to the iPhone’s GPS. You can access the coordinates of the device with GPS or cell triangulation, compass, and direction and speed of travel.
Apple’s description:
The Core Location framework lets you determine the current location or heading associated with a device. The framework uses the available hardware to determine the user’s position and heading. You use the classes and protocols in this framework to configure and schedule the delivery of location and heading events. You can also use it to define geographic regions and monitor when the user crosses the boundaries of those regions.
In this tutorial you will learn how to access the raw Core Location data, including the iPhone’s GPS coordinates and speed of travel. (more…)
Core Location GPS Source Code
Published on August 15th, 2010 in iPhone Code Snippets & Tutorials, iPhone ProgrammingI started to write a tutorial today but got a bit burned out in the process. I will finish it eventually, but here is the code for you to tinker with in the meantime.
The code demonstrates Core Location and makes use of custom protocols. The app updates a UILabel with GPS coordinates and speed of travel. Stay tuned, the tutorial will be finished up shortly!
