In this method, you append the move to the game s list of moves and return another property list to the client. This is the list that ends up as an NSDictionary in the response variable in the previous listing using the +propertyListFromData:mutabilityOption:format:errorDescription: call. For the sake of completeness, the move.plist template file on the server looks like this:

Note how you come from the native Python success boolean to the property list <true/> or <false/> version. As per the data/representation separation, the put() method shouldn t have to deal with native Cocoa data types, because the next request could possibly come from a non-Cocoa-aware client. The Cocoa-specific Django templates deal with the conversion from model to client. In Model/View/Controller lingo, you can regard the template as a controller. I have to repeat myself by saying that you shouldn t just pass a game key to the server like in the previous examples. It would be way too easy for a hacker to guess other players game keys and add arbitrary moves to them. As a minimum, you should provide your e-mail address as well and have the server code look up the game on both fields, assuming it would be quite hard for somebody to guess both the game key and the player in turn s e-mail address (except for your opponent, that is). But even better, you should authenticate the user and communicate via a secure, encrypted connection. I ll leave that as an exercise for you, once you have all the other pieces in place.

In this chapter, you took the step from a clean slate to a fully functional client/server solution ready to being deployed on Google s industry-leading platform. Admittedly, it s a very simplified solution, but it contains the components and design principles you d use in a polished App Store application that s available to millions of iPhone OS users. What was most surprising to me when I first got the core functionality up and running is the small amount of code that s needed to achieve even large and complex tasks. This is mainly because of the richness of the Python scripting language and the way Google has embraced it in its App Engine service. Coupled with the solid Cocoa framework, this chapter dealt with some of the most exciting and powerful technologies available. It sure is an exciting time to be an iPhone OS user let alone an iPhone OS developer.

Former Life As a Developer: Before switching to iPhone development I spent several years as an independent Mac OS X software developer, which followed previous experience developing Linux and embedded system software. My Mac experience goes back to the earliest days of Mac OS X, before Xcode was called Xcode and before PowerBooks started being made of metal. My experience leads me to work close to the metal , and even though I was writing Objective-C and using Cocoa on Mac OS X, my applications all ended up being various background services and utilities. Working on the iPhone I ve expanded my repertoire to cover user interface design as well. Life as an iPhone Develooper: I ve mainly worked as an iPhone contractor, developing applications for clients. The following are currently in the web store or awaiting approval: AirMe, a camera app that uploads to numerous photo-sharing sites.
The iPhone app for MSN s photoWALL web site. Mocapay, which takes the place of store gift cards, enabling users to make purchases with their phone instead of with a separate card.
On my own I wrote an iPhone app for KRCC, a public radio station in Colorado Springs, CO. This app plays the station s audio streams and includes an auto-updating program schedule, and is the basis for the code I present in this chapter.
What's in This : The chapter describes my ultimately successful quest to write an iPhone app that could play streaming internet audio with a custom user interface. Along the way I review various approaches to audio playback, including playing system sounds, using AVAudioPlayer and Audio Queue Services, Finally I settle on Audio File Stream Services as the best solution. Sample code is included for each technique. Along the way are diversions into useful related details like how to download data from a web site. Key Technologies: Core Audio Audio File Stream Services Audio Queue Services NSURLConnection
