Computational processes are abstractbeings that inhabit computers. As they evolve, proce
2、sses manipulate other abstract things calleddata. The evolution of a process is directed by a pattern of rules called a program. People createprograms to direct processes. In effect, we conjure the spirits of the computer with our spells. The iPhone is one of the most distinctive game platforms curr
3、ently available. The touch screen, integration with iTunes, programming in Objective-C, low development cost, and ease of publishing all make for a very strange but promising new development opportunity. As the newest kid on the block, the iPhone instantly captured a noticeable portion of the mobile
4、 phone market and inspired a wave of copycat devices by makers such as Motorola, Samsung, and LG. As a programmer, you might not be impressed with sales figures and market shares, but you should be interested in the viability of the iPhone as a whole. If no one owns an iPhone, no one will buy the ga

To get started with the iPhone, you ll need to get a free Apple developer account. Next you ll download the iPhone SDK on your Mac, which also contains the Xcode IDE and Interface Bu
6、ilder tool for laying out screens. (Apple doesn t provide a toolkit for Windows or any other non-Mac platform.) And because the iPhone API requires you to write in Objective-C, you will need to read a primer on the language if you do not already understand it. This chapter takes you step by step thr
7、ough all of these tasks. Apple Developer Account and Downloading the SDK The first step in setting up your iPhone development environment is to register an Apple developer account. Signing up for an account is free and gives you access to Apple s online documentation, tutorial videos, and the SDK do
8、wnload: 1. Go to http:/ 2. Click the Register link, and then click Start Now. Choose the option to create a new Apple ID, or to log in using an Apple ID from an iTunes or App Store account. 3. Once you have registered, you can log in to the iPhone Dev Center. 4. Apple may already have emailed you a
9、link to download the free SDK, or you may choose to download the SDK using the link from the website. Note that you should not download Xcode separately because it is included within the SDK download package (and the version of Xcode that comes with the SDK may be newer than what is otherwise availa
10、ble). 5. Once downloaded, install the SDK, which will make Xcode and Interface Builder accessible to you in the /Developer/Applications folder on your hard drive (you can also activate Spotlight and search for Xcode and Interface Builder to launch either application quickly). The free developer acco
11、unt will allow you to build applications and run them in a simulator on your Mac. However, to load your application onto a phone, you will also 第 3 页共 67 页 need to sign up for the paid developer program. This requires a small annual fee, so even if you are a private developer, it wont hurt your wall
12、et too much: 1. Go to http:/ 2. You will have two options: Standard Program and Enterprise Program. If you are writing games for the general public, you probably do not want the Enterprise Program. If you read closely, you will notice the Enterprise Program is actually for creating applications that
13、 only you and your company will use internally. If you plan to create games that will be sold via the App Store, rest assured that the Standard Program is the correct choice for you. 3. Select Enroll Now and log in if necessary. 4. You now have another choice: enroll as an individual or as a company
14、. If you choose Individual, you will not be able to add other programmers or quality assurance members to your account, which is necessary to distribute your application to others during the development and testing process. However, if you select Company, you will be required to provide detailed inf
15、ormation about your company. 5. Continue through the website, selecting the appropriate information, until you arrive at a screen that says “Thank you for submitting your enrollment.”Now you must wait for an email from Apple (which may take on the order of a month to arrive). Signing up for the paid
16、 developer program will also give you access to beta releases of future versions of the iPhone OS and SDK, but only during the times at which Apple chooses to make them available. It is good to get your paid developer account enrollment going as soon as possible so that it will be available when you
17、 actually need it. Application Bundles When you build an application using Xcode, the end result is called an application bundle. In Mac OS X and the iPhone, an application bundle is a special type of directory 2 | Chapter 1: Introduction to the iPhone Download at WoweBook.Com that holds an executab
18、le file and the resources needed to run it. This includes an icon to represent the application, files with special information about the application, and any images or sounds the application uses. In the Finder, an application bundle simply appears as its application icon； right-click or Ctrl-click on it and select View Package Contents from the menu to see whats inside. Although you cant do this on the iPhone, you can find iPhone applications in the iPhone Simulator. If you have the iPhone SDK installed,
