Question

I am still using the old facebook graph api for posting stuff on a users wall in my app. Since iOS6 facebook has been integrated into the OS. How can I use it to post stuff? I wanna use it the same way as the twitter framework:

    TWTweetComposeViewController *tweetViewController = [[TWTweetComposeViewController alloc] init];
    [tweetViewController setInitialText:@"bla bla bla"];
    [self dismissModalViewControllerAnimated:YES];
    [self presentModalViewController:tweetViewController animated:YES];

Answer 1

Starting with iOS 6 you can use SLComposeViewController for all supported service types like Twitter, Facebook and Weibo.
Note: Don’t forget to add the Social.framework

if ([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook]) {
     SLComposeViewController *fb = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];
     [fb setInitialText:@"bla bla bla"];
     [self presentModalViewController:fb animated:YES];
}
