Example application to use with DropboxTi SDK module available in the Appcelerator Marketplace.
BEFORE USING THIS APP YOU MUST CREATE A FILE CALLED KeysNotForGit.js
In that file put:
var myAppKey = "<< REPLACE WITH YOUR KEY>>"
var myAppSecret = "<< REPLACE WITH YOUR SECRET >>";
It is suggested that you use this app either on the Simulator or make sure you have Xcode Organiser opened as lots of return information appears in the console rather than in UI. It's a demo app ;)
