Here are the slides from my presentation at the 2010 Apple University Consortium /dev/world conference.
Apple Push Notifications are an integral part of many applications, from games like "Words With Friends" to VOIP call notification, but for the non-expert developer they can be a source of mystery. Apple's "Local and Push Notification Programming Guide" provides details of the binary protocol, SSL certificates and other details which are hardly beginner material. Additionally the guide makes little mention of correct UTF encoding and other small details which create more difficulty for those unfamiliar with data encodings etc. And finally a persistent server is required which can handle the protocols. This talk will take attendees through: an understanding of the service overall; the protocol and its limitations; responding to notifications in the iOS application; approaches to implementing a server in Perl, Python or Ruby.
Mark Aufflick has been involved in the Apple industry since his first job in 1995 and finally put his Computer Science degree to use becoming a freelance developer in 2000. Since then he has developed back end, web and gui applications for various Unix platforms, MacOS and iOS - for both corporate giants and small businesses. Mark has presented on programming topics in fora such as Sydney University's Web Engineering Group and CocoaHeads. These days Mark is an iOS and Mac developer with his company Pumptheory as well as the convenor of Sydney CocoaHeads.
