The SLComposeViewController class was added in iOS 6 allowing you to present the user with a view for posting to supported social networking services – Facebook, Twitter, and Sina Weibo.
Today I came across a user interface control known as REComposeViewController from Roman Efimov that makes it easy to create composers styled in exactly the same way, but for whatever social network you choose.
Here’s an image of a composer view created for Foursquare:
The REComposeViewController extends UIViewController and can be styled in the same way including styling with the UIAppearance protocol.
You can download REComposeViewController on Github here.
A great way to keep a uniform look if you want to support sharing in social networks other than those supported by iOS.
