The use of web basic programming and development
It has been quite some time, apple made a great prosperity all around the world since the iphone issuance. It introduced mainly for the American market, but in a year’s time, can provide the world. There are many user can now use, but I feel it is very important to existing customers and potential customers have a basic concepts and bring equipment general potential, makes its programmers get all value for their money.
The apple is a kind of experience, you will feel it from the moment you hold it in hand. Some people like their functions, and some of its sleekness, but to me it cabinet form, the larger, more extensive display and touch technology, give me.
All users know “touch technology equipment, especially the contact, if a user use only two fingers touch the screen at the same time different place. But touch technology is not only the” apple “. Some important features include:
1. Position of discovery: using GPS technology, it can figure out its position in the world at that particular time.
2. Accelerometer and positioning: but has the ability to detect moving in 3d space among.
3. Programmable camera, address book
Technically, exists in two largely similar version of the original distribution in 2007 and 2008 3G release. Each device containing a 620 MHZ arm CPU. The CPU is special design, improve the battery performance and reduce heat. Two versions including 128 MB memory and 4, 16GB flash memory. The biggest difference between the two devices concentrated in the global positioning system (GPS) and networking.
Some other technical specifications:
May 1 is based on the apple’s OS, which itself is built on Unix.
Apple 2. has 480 x 320 touch screen.
3. Support network and wan Internet use wireless networks.
4. Use GPS in wireless networks.
Programming basics
In 2008, apple apple release, developers, form tool that allows programmers development to application.
Can let you form of development of two types of program? Website development and local network application development.
Can use a – C form of language, this is a kind of outspread to the C language. As a – C implementation of apple, built around objects. It is used in the entire apple operating system? Closing framework. The window, views, buttons, slider and controller exchange information of events and forms of measures to make the program operation.
In each object a – C is represented by a header file (. H) and a source code file (afternoon). Although, apple operating system framework provides many standard classes, but sometimes you must write their own subclasses. When you write your own children, you need a new title and source of lesson representative new subclasses. The operating system is the apple into four layers, cocoa contact, media, core services, core operating system. Each layer contains various frameworks that you can use in your application/plan.
A developer you will need the following:
1. A Mac operation sx leopard v10.5.4 or higher
2. For the SDK the iPhone apple operating system, in which you can download from apple website. The SDK the iPhone tools and utilities contains all you need to develop network application.
Now, the next step is to let his registration in development projects and an apple membership dues. This registration get you an apple guarantee proof that can be used to test the application developed equipment itself.
You? I also need a web and XCode form IDE along with the SDK. Now, we are ready to start coding your first Internet applications.
