When it comes to iPhone or iPad application development the first
thing that you need to check is that you are using an Intel based
Macintosh system that runs on the Mac X operating system. You will need
to use the Software Development Kit (SDK) that is available for free
from Apple to create your applications.
In
order, to download your SDK from the Apple website you require a user
name to log in. If you do not already have one, do not worry you can
quickly sign up for a free one from the website too. After you have
downloaded the Xcode software and installed it, unzip the 'Hello World'
application. In the unzipped directory you want to click on the Xcode
project file.
This will get you into the Xcode development environment. By opening up the 'classes' folder you can view all the editable classes files in this project. If you are not familiar with Objective C programming code before, the source code you will be looking at will not make any sense to you at all.
However, built into the software is the 'Research Assistant'. You can use this to find out any information about certain keywords in the source code. You should know however that some of the keywords do not work with the this assistant, so you would need to look those up elsewhere.
To activate this tool, simply highlight the keyword you want more information. Next click on 'Help' tab on the top menu then 'Research Assistant' and then it gives you a nice brief help summary. It will show an abstract, related documents and right at the bottom it will also show other sample code.
What you can do to familiarize yourself with the programming language is to view as many of the samples available as possible and use the research tool to get more information on the various classes and keywords. You should be able to pick up on it pretty quickly especially if you have used other programming languages like C++ or Java before.
