Ever since Apple launched the iPhone in the US, people all over the world have put it in their hands, so there are a lot of people using iPhones today. 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 shape.
The touch screen can be touched with two different fingers in different places. IPhone also has a global positioning system so you can find out where you are. It has the ability to detect motion in three dimensions, along with other features such as a camera, address book, and a programmable vibrator. Therefore, the iPhone is more than a phone. It is powered by a 620 MHz ARM CPU with reduced heating, along with a 128 MB DRAM and from 4 to 16 GB of Flash memory. It uses an Apple OS X, built 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. There is a developer toolkit, iPhone SDK, that allows you to develop iPhone applications. There are two options: web-based applications and native applications. Web apps run in a browser using HTML, CSS, ASP, Java, .NET, Ruby, or JSP, and native apps run in the built-in frameworks provided by the iPhone development kit.
The language you write your code in is called Objective-C, as implemented by Apple. It is an object-oriented language, so it presents encapsulation, inheritance and polymorphism of methods and data that focus on Objects, accessibility and the connections between them. In this way, you can make buttons, views, windows, sliders and controllers to maneuver 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 in 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 basic level of the Core OS contains the kernel software that deals with networking, threading, input / output, and memory. The core services provide you with the frameworks for all applications, the media provides protocols for audio and video, and Cocoa touch is the one that allows you to control events, windows, and user interfaces.
You must use an Intel Mac computer with MAC OS X Leopard, and you must use the iPhone SDK, which is downloadable. The latter can test your application in the absence of the iPhone device. In addition, you must register for the development of the program at Apple.
IPhone game apps have already been created. They use the phone’s motion sensor devices to steer the race cars in racing games. Other applications use Wi-Fi to connect you to the Internet like a laptop or computer.
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. These companies may not be more than two years old, but some have worked in IT for much longer, so their experience may be useful to you.
