Getting users to share your app, or content within on a social network can be a great free way to gain publicity.
Here’s a handy library from Robert Goncz for creating social sharing buttons.
The buttons created by this library are UIButtons so they can be used wherever you can place a UIButton.
Another advantage of these buttons is that no files are used, but rather the buttons are drawn using core graphics so they can be scaled to your desired size, and the coloring is easily customized.
The available sharing buttons include Facebook, twitter, Google+, Pinterest, Dribble, Flicker and E-mail.
You can find GRButtons on Github here.
A nice library to have around whenever you find yourself adding social buttons to an app.
