Just a public service announcement that my Twitter plugin, which is free, is up on the Corona Labs plugin store (store.coronalabs.com) and can be used starting today. If you have any interest in integrating Twitter into your apps, I think you may find it very useful, and hopefully easy to use.
Full documentation on the plugin, plus a downloadable sample project, can be found at my website: http://twitter.plugin.jasonschroeder.com.
I created the Twitter plugin for Corona SDK to give Corona developers an easy way to access the full range of Twitter’s REST APIs from inside their apps, making it simple to get data from or post information to a Twitter user’s account with as little as a single line of code. The plugin automatically handles oAuth authentication, and persistently saves a logged-in user’s token data, so they’ll only need to log in and authorize your app once, even across multiple sessions, until they are manually logged out or revoke your app’s access to their Twitter account. The plugin also comes with a set of “convenience functions” that return Lua tables and/or Corona display objects, for easier access to common-use applications without the need for developers to wade through the raw JSON data that Twitter’s REST APIs return.
Here's a video of the sample project, which gives you some idea of how it works and what it can be used for:
