Hello everyone. Welcome to another screencast. Today we will be looking into the MapKit, a new API’s made available by Apple in the iPhone OS 3.0 release. The MapKit allows simple access to the map seen in the maps application.

As you may have seen, there are quite a few services out there offering free leaderboards. These are great and all, but sometimes you want to have complete control over your data. I have put together a complete tutorial detailing step by step how you can create your own online leaderboard. This will also give you a very simple introduction to interfacing with web services.

The NSArray is a huge workhorse that we use quite frequently without even thinking about it. The NSArray class isn’t just your ordinary array. Not only does it provide random access, but it also dynamically re-sizes when you add new objects to it. While I won’t go over every method in NSArray (there are quite a few), I will discuss some of the more important ones that are most commonly used. Let’s take a closer look at this class.

This will be a simple tutorial showing you how to access the iPhone’s photo library as well as the camera. Since the 3.0 update, the methods for picking photos have been . So this will be a 3.0 and above tutorial.

Ok, I will be finishing up this series by showing you guys how to add basic audio to your game. Since this is a beginner tutorial, I won’t go into complex audio using OpenAL or Audio Queues. Today, we will just be playing short sounds (less than 30 seconds). This will be the easiest way to do audio if you don’t require any background music (I guess you could do a nasty hack and loop a 30 …

Ok, So it’s time to wrap up this series. Today I will be showing you how to add a few “bells and whistles” that will make your game more complete. Let’s start by adding a splash screen to your game (Again I truly apologize for the lack of graphics skillz. Photoshop and I are not friends).
Creating a Splash Page
We will be adding a splash page that will fade out into our main game screen. Start by downloading …

Ok folks, here it is. The next tutorial in our iPhone game programming tutorial (sorry for the delay). Today, I will be discussing the basics of player interaction, simple game AI, and game logic. We will also be exploring how to do simple collision detection so we know when the ball hits a paddle. Per popular request, I will be adding “Challenges” to the bottom of the tutorials from now on to give some more advanced ideas for …

This is the first in a multipart series where I will be teaching you to create an iPhone game from the ground up. As many of you know, OpenGL and Quartz have quite a steep learning curve. This tutorial will simplify the development process and not use either one of those technologies. For our graphics, we will simply use UIImageViews.
In this tutorial series, I will teach you about every aspect of developing an iPhone game. …
