This is how I actually use it in my app though. Smoother and lets the controller do the hard work.

- (IBAction)postToFacebook:(id)sender {
  if(![SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook])  {
        NSLog(@"log output of your choice here");
  }
  // Facebook may not be available but the SLComposeViewController will handle the error for us.
  self.mySLComposerSheet = [[SLComposeViewController alloc] init];
  self.mySLComposerSheet = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];
  [self.mySLComposerSheet setInitialText:[NSString stringWithFormat:@"I found this Thing, check it out at SomeWhere:\n %@ \n", [self someURLString]]];
  [self.mySLComposerSheet addImage:self.photos.firstObject]; //an image you could post

  [self presentViewController:self.mySLComposerSheet animated:YES completion:nil];

  [self.mySLComposerSheet setCompletionHandler:^(SLComposeViewControllerResult result) {
        NSString *output;
        switch (result) {
              case SLComposeViewControllerResultCancelled:
                    output = @"Action Cancelled";
                    break;
              case SLComposeViewControllerResultDone:
                    output = @"Post Successfull";
                    break;
              default:
                    break;
        }
        if (![output isEqualToString:@"Action Cancelled"]) {
              // Only alert if the post was a success. Or not! Up to you. 
              UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Facebook" message:output delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil];
              [alert show];
        }
  }];
}
