Proto.io “Prototyping the most popular apps” is a series of videos where we recreate popular UI’s and interactions with Proto.io.
From the instructor (Constantinos Demetriadis):
Foursquare’s latest application introduced a new way to turn on specific functionality in the app.
They used a sliding switch on the header, which toggles neighborhood tracking. This was interesting to build as you only have a single container which changes depending on the status of the tracking functionality.
Note: If you haven’t been exposed to variables in Proto.io, you should watch the introductory video beforehand.
