This is a sample code to show the different ways of posting to Facebook.
One simple way is using SLComposeViewController but it's not very powerfull.
The SLRequest way required a little bit of digging in Facebook's docs and [this post on SO](T: http://facebook.stackoverflow.com/questions/12644229/ios-6-facebook-posting-procedure-ends-up-with-remote-app-id-does-not-match-stor) helped me a lot!
It's a 2 step process though the first time (which, given, can be done in one):
- An initial step is for the user to "allow the app" to post for him
- Then, on each "post" it's asked again
It means the very first time it's required to show 2 steps (the first one could done in some settings or else, but since you don't need a setting with the Facebook credentials in your app...)
Enjoy!
