In effect, we conjure the spirits of the computer with our spells. The iPhone is one of the most distinctive game platforms curr

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

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.

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

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

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

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

Select Enroll Now and log in if necessary. 4. You now have another choice: enroll as an individual or as a company

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

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
