title: Post on FB friends wall in iOS using SLRequest and Device Settings Credentials
body: <p>I am developing an iOS app in which I have to invite to user Facebook Friends to join the app.
  I am using Social Framework to do so. I have successfully posted on FB wall of logged in user but there is a problem in the message which I posted. the message says that "User has shared a link via sample app. Pleas join this awesome app.". I want the message:</p>
  
  <p>"User -> Friend
  Please join this awesome app.".</p>
  
  <p>I want it like when it appears when we write on Friend FB Wall. </p>
  
  <p>I have added the "to" parameter in which I am passing the friend's unique FB id. But it's not working. </p>
  
  <p>Below is the code which I am using for this:</p>
  
  <pre><code>[accountStore requestAccessToAccountsWithType:facebookAccountType options:dict completion:^(BOOL granted, NSError *error)
  {
      if (granted)
      {
         __block ACAccount * facebookAccount;
  
  
  
     NSDictionary *options = @{ ACFacebookAppIdKey: **FBAPPID**, ACFacebookPermissionsKey: permissions, @"ACFacebookAudienceKey": ACFacebookAudienceFriends };
  
     [accountStore requestAccessToAccountsWithType:facebookAccountType options:options completion:^(BOOL granted, NSError *error)
     {
        if (granted)
       {
           NSArray *accounts = [accountStore accountsWithAccountType:facebookAccountType];
                           facebookAccount = [accounts lastObject];
  
          NSURL *postURL = [NSURL URLWithString:@"https://graph.facebook.com/me/feed"];
  
              NSMutableDictionary *postDict = [NSMutableDictionary dictionaryWithObjectsAndKeys:
  **FRIENDID**, @"to",**FRIENDNAME**, @"name",@"Testing of app.", @"caption", @"please join this awesome app.", @"message", nil];
  
          SLRequest *postToMyWall = [SLRequest requestForServiceType:SLServiceTypeFacebook requestMethod:SLRequestMethodPOST URL:postURL parameters:postDict];
                           [postToMyWall setAccount:facebookAccount];
  
                           [postToMyWall performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error)
                            {
                                if (error) {
  
                                }
  
                                else
                                {
                                    NSLog(@"Post successful");
                                    NSString *dataString = [[NSString alloc] initWithData:responseData encoding:NSStringEncodingConversionAllowLossy];
                                    NSLog(@"Response Data: %@", dataString);
  
                                    [self performSelectorOnMainThread:@selector(postSuccess) withObject:nil waitUntilDone:NO];
                                }
                            }];
                       }
                       else
                       {
                           NSLog(@"rfc");
                       }
                   }];
  
  
   }
  
     else
              {
                  [self performSelectorOnMainThread:@selector(showerrorAlert:) withObject:error waitUntilDone:NO];
              }
          }];
  </code></pre>
  
  <p>Please if anyone can give a solution for this. I can use Facebook Framework also but I need to authorize the user and fetch his/her friend list using the credentials stored in iPhone Device Settings. So if you have an alternate solution then please let me know. </p>
