Tutorial: creating a login screen

Out of the box, Stacker comes with a pretty good example app that can serve as a basis for your own iPhone apps. But what about getting users to log in to your app?

I'm going to show you a very simple technique I like to use to show a "welcome screen" that asks a user to log in (or sign up). Even though the server code is written in Rails, the technique is simple enough that it can be applied to most other frameworks without a lot of effort. We'll be building off of the example app, called GameRoom, so be sure to try to get the demo working by following the getting started documentation.
