Have you checked http://developers.facebook.com/docs/guides/mobile? Facebook has an SDK for all you need.

Add Social.Framework, then add below code

    {
     if([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook])
     {
         SLComposeViewController *FacebookSheet = [SLComposeViewController        
composeViewControllerForServiceType:SLServiceTypeFacebook];
         [FacebookSheet setInitialText:@"Your text"];
         [FacebookSheet addURL:your url];
         [FacebookSheet addImage:[UIImage imageNamed:@"image.png"]];    
         [FacebookSheet setCompletionHandler:^(SLComposeViewControllerResult result) 
         {
            switch (result) 
            {
             case 0:
             {
               SLComposeViewControllerResultCancelled:
                NSLog(@"Post Canceled");
                UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Cancelled"
                 message:@"You must be connected to the internet to use this app."
                  delegate:nil
                   cancelButtonTitle:@"OK"
                    otherButtonTitles:nil];
                     [alert show];
               break;
             }
             case 1:
             {
               SLComposeViewControllerResultDone:
               NSLog(@"Post Sucessful");
               UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Successful"
                             message:@"Posted successfully."
                             delegate:nil
                             cancelButtonTitle:@"OK"
                              otherButtonTitles:nil];
                              [alert show];
               break;
               }
               default:
               break;
              }      
              }];
             [self presentViewController:FacebookSheet animated:YES completion:nil];
            }
            else
            {
               UIAlertView * alert=[[UIAlertView alloc]initWithTitle:@"No facebook accounts"      message:@"There are no facebook accounts configured. You can add or create a facebook account in phone settings." delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil, nil];
            [alert show];
            }
    }
