An iPhone app moves from screen to screen as the user taps and swipes. You can paper prototype or you could use a digital tool to get the feel of your app. Or you could just start developing it using the new storyboard architecture included in Xcode. This session will show you how to use Storyboards to layout and create an application in iOS5 for iPhone or for iPad.
Mobile devices are so useful because they can get on the net with their built-in wi-fi or cellular data radios. But how does this work? In iOS, we have a slew of networking APIs, each appropriate in different situations. From decades-old BSD sockets to the new-in-iOS-5 iCloud, there are a wide range of networking calls available to your app, and an equally wide range of semantics in how to use them. In this talk, we'll start with high-level abstractions like iCloud and other objects that can either load from or save to a URL, then progress down through the stack, grabbing arbitrary content from URLs, self-networking with Bonjour and Game Kit, and finally accessing the socket layer with CFNetwork and BSD sockets.
