Our first task is to design our user interface and the interaction between the various widgets and views. Like the previous task, we will have three views: the start view, the social view, and the tweet view.
We'll begin with the start view. This will be a very simple view. It is entirely optional in this app as all we'll be doing is explaining the app and providing a way to move to the main view.
With that in mind, our sketch is shown in the following screenshot:
In the preceding image, we have a Start button (1) that will push the social view onto the view stack. We also have some explanatory text (2).
