Ever since Apple launched the iPhone in the US, people all over the world got their hands on it, so today there are many people using iPhones. It is an amazing piece of technology that can be bought at an average price and incorporates touch technology with a large screen and a compact curved form.
The touch screen can be touched with two different fingers in different places. iPhone also has a Global Positioning System so you can know where you are. It has the ability to detect motion in three dimensions, along with other features like a camera, address book, and a programmable vibrator. Therefore, the iPhone is more than just a phone. It operates on a 620 MHz ARM CPU with reduced heating, along with 128 MB DRAM and from 4 to 16 GB of Flash memory. It uses an Apple OS X, based on Unix. The great news about the possibilities of the iPhone is that you can create your own applications in addition to the ones provided. A developer toolkit, iPhone SDK, has been released that allows you to develop iPhone applications. There are two options: web-based apps and native apps. Web apps run in a browser using HTML, CSS, ASP, Java, .NET, Ruby, or JSP, and native apps run on the built-in frameworks provided by the iPhone development kit.
The language you write your code in is called Objective-C, implemented by Apple. It is an object-oriented language, so it features method and data encapsulation, inheritance, and polymorphism that focus on objects, accessibility, and the connections between them. In this way, you can make buttons, views, windows, sliders and controllers to handle your information within the program and interact with it through events and actions.
Standard classes are available, but you can create your own classes that inherit something from the regular ones and have them interact with your project. The operating system comes in four layers (Core OS, Core Services, Media, Cocoa touch), each layer contains the frameworks that you can use for your application. The base level of the Core OS contains the kernel software that deals with networking, threading, input/output, and memory. Core services give you the frameworks for all the apps, Media provides protocols for audio and video, and Cocoa touch is the one that lets you control events, windows, and user interfaces.
You must be using an Intel Mac computer running MAC OS X Leopard, and you must be using the iPhone SDK, which is available for download. The latter can test your application in the absence of the iPhone device. In addition, you must register for program development at Apple.
Game applications have already been created for the iPhone. They use the phone’s motion sensor devices to drive the racing cars in the racing games. Other apps use Wi-Fi to connect to the Internet like a laptop or desktop.
If you are interested in developing a mobile game or an iPhone application, you can search for an iPhone application development company on the Internet. Such companies may not be more than two years old, but some have been in IT for much longer, so their experience could be useful to you.
