Throughout the book we re going to talk about two major categories of programming for the iPhone: web development and SDK programming. Web development involves the creation of web pages that work well on the iPhone. These pages use standard web technologies such as HTML, Cascading Style Sheets (CSS), JavaScript, PHP, Ruby on Rails, and Python; iPhone-specific technologies such as the WebKit, iUI, and Canvas; and iPhone-specific tools like Dashcode. SDK programming involves the design of programs that run natively on the iPhone. These programs are written in Objective-C, compiled in Xcode, and then deployed through the iPhone App Store. We ll compare the two programming methods in the next chapter; then we ll dedicate part 2 of this book to learning all about iPhone web development and parts 3 and 4 to digging into Apple s iPhone SDK.

The iPhone s browser is a mobile version of Apple s Safari. It s a full-fledged desktopgrade browser with access to DOM, CSS, and JavaScript. However, it doesn t have access to some client-side third-party software that you might consider vital to your web page s display. The two most-used third-party software packages that aren t available natively to the iPhone are Flash and Java. There was some discussion of a Java release in 2008, but the SDK s restriction against downloads seems to have put that effort on hold. We ll talk about these and other missing technologies more in chapter 3. Beyond listing what s available for the iPhone Safari browser (and what s not), we ll also note that it works in some unique ways. There are numerous small changes that optimize Safari for the iPhone. For example, rather than Safari s standard tabbed browsing, individual tabs appear as separate windows that a user can move between as if they were individual pages. iPhone s Safari also features unique chrome, which is its rendition of toolbars. These gray bars appear at the top and bottom of every iPhone web screen. The chrome at the top of each page shows the current URL and features icons for bookmarks and reloading; we ll investigate how to hide this chrome when we look at iPhone optimized web development in chapter 3. The chrome at the bottom contains additional icons for moving around web pages and tabs. It s a permanent fixture on iPhone web pages. This iPhone chrome is more noticeable than similar bars and buttons on a desktop browser because of the iPhone s small screen size.

Other iPhone hardware features Cell phones feature numerous hardware gadgets of which a camera is the most ubiquitous. The iPhone includes all of the cell phone standards, but also some neat new elements, as outlined in table 1.1.

Table 1.1 The iPhone is full of gadgets, some of them pretty standard for a modern cell phone, but some more unique. Notes The iPhone contains three accelerometers. Their prime use is to detect an orientation change with relation to gravity which is to say they sense when the iPhone is rotated from portrait to landscape mode or back. However, they can also be used to approximately map an iPhone s movement through three-dimensional space. Could this make the iPhone the next Wii This standard protocol for modern cell phones allows access to wireless devices. The iPhone uses the Bluetooth 2.0+EDR protocol. Enhanced Data Rate (EDR) allows for a transmission rate about triple that of older versions of Bluetooth (allowing for a 3.0 Mbit/s signaling rate and a practical data transfer rate of 2.1 Mbit/s). Another de facto requirement for a modern cell phone. The iPhone s camera is 2.0 megapixel. The original iPhone doesn t support real GPS, but instead offers the next best thing, peer-to-peer location detection. This faux GPS triangulates based on the relative locations of cell phone towers and wi-fi networks for which real GPS data exists, and then extrapolates the user s location based on that. Unfortunately the accuracy can vary dramatically from a potential radius of several miles to several blocks; still, it s better than no GPS at all. The 3G iPhone includes a true Assisted GPS (A-GPS), which supplements normal GPS service with cell network information. Although there is a difference in accuracy between the two types of GPSs, they can both be accessed through the iPhone SDK using the same interface.
