Introduction
Hey guys. So usually the posts we put up here involve screencasts and presentations, but we are going to start also posting small less time consuming pieces for the site. Today I bring to you a small project involving NSTimers. Today we are going to build an app that represents a horse race. We will create a view with 6 small UIView squares with a blue background at the bottom of the screen, we will use a timer to move …

Hello everyone, welcome to my second screeencast. This is going to be the first in a series of screencasts that are focused at people just beginning to work with Objective C and Cocoa. For many reasons the beginnings of learning cocoa development can be frusterating and lonely to a point. Only now is Objective C and Cocoa development gaining the kind of momentum to drive the creation of resources such as iCodeBlog and others.

Hey everyone, welcome to my first of many screencasts coming in the next few weeks. Today I am going to show you how to layout a UITableViewCell in Interface Builder and have a UITableView populate with those type of cells. I am adopting a new structure for my screencasts which will be 5 or so mintues of keynote slides giving background info followed by 20 – 25 mintues of step by step development. The entire video will be directly below …
I have noticed recently many people wanting to create games for the iPhone and are unsure where to start. Â A common misconception is that you must use OpenGL ES to create any game with graphics. Â I am going to show you today how you can do some simple animation by moving a ball around the screen. Â We will not be using OpenGL ES to move the ball. Â We will simply be using an NSTimer and a UIImageView.

In this tutorial, I will be showing you how to use UITouch to get the location of where a user touches on the screen. We will be using this knowledge to drag a UIImageView around.
Learning how to use UITouch is the first steps in creating applications that are not navigation based (or don’t only use Apple’s built in components. Later on, we will begin some basic game development that will utilize UITouch.

In this tutorial, I will be showing you how you can save and retrieve different types of data using the NSUserDefaults object. Saving this way is great for when you want to save small amounts of data such as High Scores, Login Information, and program state.
Saving to the NSUserDefaults is great because it does not require any special database knowledge. So if you don’t want/have an SQLite3 database for your app, this would be the way to go.

The goal of this tutorial is to show you how to populate a UITableView with data from an array of objects. This will be the building block to display XML data as well as SQL data.
The theme of this application will be fruit. We will create an array of “fruit” objects that have some additional information besides the name. We will populate a UITableView with the names of the fruits. When the user selects a fruit …
This tutorial will focus on transitioning from one view to another. We will be utilizing Apple’s UINavigationController. I will be using the code from the “Hello World” tutorial that I previously wrote. So if you have not completed it yet, go ahead and do it and come back to this page. (It’s quick I promise). You can view it here.
In this tutorial you will learn:
Finally, we get to write some real code! In this tutorial, I will show you how to create an interface using Interface Builder and connect it to your code. We will be creating a UITextField, UILabel, and a Button. Now, don’t be intimidated that this tutorial is so long. I have really went into detail explaining everything as I go. You could easily scan over it and get the gist of it. Here’s how the application …
