by on 28. Mar, 2011 in Hello, and welcome to another iOS Development tutorial. Today we are going to learn about UIPickerViews and how to switch viewcontrollers (I’ll explain what that is later). I’ll start off by explaining that picker views work fairly the same way as table views, so if you did the last tutorial then you should have no problem understanding this one. In the last tutorial I took a poll about whether we should use Xcode 4 or Xcode 3 in the tutorials and it looks like Xcode 4 won by a long shot. So, we will be using Xcode 4 in our tutorials from now on. I will try to explain where things are in Xcode 4 and how things work, but be patient, as I am learning as well. If you are not a part of the iPhone developer program, you download Xcode 4 from the Read More

by on 14. Mar, 2011 in Hello again, today we will learn about UITableViews and NSArrays, but before we start I need everyone who reads these tutorials to vote on the poll below, since it will determine how the next tutorials will be presented. Since Apple released the new version of Xcode (Xcode 4) I need to know whether we should use Xcode 4 or Xcode 3 for the tutorials. Xcode 4 does cost $5, but I think it’s well worth the price (in my opinion). You can find Xcode 4 in the Mac App Store. If you don’t vote you will have no room to complain about which one was chosen. But for today we will just use Xcode 3. Lets get started. A table view is an object that display information by sections and cells in a scrollable window. Here are some examples of table views: So what is Read More

by on 14. Feb, 2011 in To get started with iPhone development you will first need to learn some things… Firstly, some history is always useful when learning something new. iPhone apps are written in a computer programming language called Objective-C which was originally created by a company called NeXTSTEP. Apple soon purchased Objective-C and used it to develop their operating systems. Objective-C is used on many different platforms today, like, iOS and Mac OS X. That’s enough history for now, we’re not in high school and it’s not incredibly important to this series of tutorials. I’m writing this series of tutorials assuming that you have no experience with computer programming so there are really no prerequisites to this series, other than knowing how to run a computer with general competency. Step 1: You are going to need a few things before you can get started developing apps for the iPhone, Read More
