iOS app for Java developer

(devoxx uk) You boss said: "I need an iPhone version". And you're a Java guy...

So, that's mean: Objective-C! You're scared of this barbarian syntax? Relax Objective-C is a cool dude. Xcode is not a bad guy, he’ll help you. And if you want to stay in known territory: AppCode is here. Using template, you get up and running in no time. UI designing with interface builder and storyboard are dead easy to start with. Your app has to be connected to your enterprise cloud-based server application? No worries, all the plumbing for accessing REST services feels fluent using iOS AeroGear libraries.

Join us to follow the tribulations of a Java guy in the world of iOS programming. And of course, the unbearable suspense: will he get his iOS app on time?

Easy enterprise mobile app

You want to build a cool app to share your photos on Twitter, Googgle+, Facebook... Tackle all the 'cool' social networks. First thing you need to do is: authenticate and authorize your app for each providers.

Good news is: there is a common protocol for that. Its little name is 'OAuth2'. Each provider comes with an iOS sdk to ease the OAuth2 dance, but of course, each has its own API.

Ouch! And what you really want is use the same API for all them. Let's see how you can implement OAuth2 protocol and provide a common API across providers. Much easier than his elder brother OAuth, we will dive into OAuth2 protocol and see the challenges of implementing it from a native app perspective.
