Does anybody happen to know a good tutorial on placing the ‘I like it’ button into the application? I’m especially interested in Facebook SDK 3.0 and the so-called Built-in Like button.
So far, I’ve been searching through google and stackoverflow but I haven't found anything about SDK 3.0.
Publishing a built-in like is very similar to publishing a custom Open Graph action. The best resource for learning about publishing built-in likes is Facebook's reference page:
https://developers.facebook.com/docs/opengraph/actions/builtin/likes/
Please see this post regarding likes and this post to see an alternative of adding a like button.
Ideally you could create a html iframe that links to the page. obviously this would open up the webpage to the link of the facebook like button. atm i believe that's how temple run achieve this. does the trick. They're getting many likes from users directed from the ios app temple run itself.
