xiv | Preface

It seemed that the users of the applications disagreed. It’s arguable why this is the case,

but it’s very hard to make native-looking web applications that can be reused across

many different platforms, though it is possible. Just as applications on the Mac desktop

that have been ported from Windows tend to stand out like a sore thumb by not quite

working as the user expects, web applications, especially those that are intended to be

used across different platforms, tend to do the same.

If you integrate your application into the iPhone ecosphere, make use of the possibilities

that the phone offers, and optimize your user interface (UI) for the device, the user

experience is much improved. It’s also really hard to write web applications that work

well when you need to design for a smaller screen, implying as it does a simpler UI and

less exposed functionality, without using native controls.

Why Write Native Applications?

The obvious reason to use the native SDK is to do things that you can’t do on the Web.

The first generation of augmented reality applications is a case in point; these needed

close integration with the iPhone’s onboard sensors (e.g., GPS, accelerometer, digital

compass, and camera) and wouldn’t have been possible without that access. Although

the iPhone’s Safari browser supports the new geolocation capabilities HTML 5 pro

vides, this doesn’t alleviate the problem entirely. It’s doubtful that all platform-specific

hardware is going to get the same sort of treatment, so it’s unlikely that you will see the

arrival of augmented reality web applications.

If you are coming from a web development background, you may be

interested in the cross-platform PhoneGap framework. This framework

provides native wrapper classes and allows you to build native applica-

tions in HTML/JavaScript on a range of mobile platforms. One of the

platforms it targets is the iPhone. I talk about PhoneGap, and the other

alternative native development platforms for the iPhone, in Chapter 13.

Sometimes it’s not about doing things that can’t be done; it’s about doing things faster,

and doing client-side error handling. For instance, the Apple iTunes and App Store

applications that are provided with the iPhone are actually web applications wrapped

inside native applications. Just like the iTunes Store on the Mac, the main display you

see is a web page, but the surrounding infrastructure is a native application. This means

that while the application can’t do a lot without an Internet connection, it can at least

start up.

But those are extreme examples. A lot of the applications in the App Store combine

remote data and native interfaces. Without access to the network, some of the UI is

generally disabled. However, native applications can be built to degrade gracefully

when the device’s network connection disappears or if it was never present in the first
