Login and list Facebook friends using Social Framework

Question

Could someone give me some pointers on how to integrate this? my goal is to get list of friends who installed my app (fb app). initially I need to login user to my app first and list friends who have / haven't installed the app.

PS : I don't want to use Facebook SDK. I had nightmares in the past due to facebook did countless time changing the sdk.

=========== UPDATE

I've successfully login and list my facebook friends. But now problem to list my friend who have the app and list picture as well. I tried this :

URL : https://graph.facebook.com/me/friends?friends?fields=id,name,installed,picture

which give me OAuthException : An active access token must be used to query information about the current user. problem.

I tried also in API Graph, it works without mentioned error.

if I try only me/friends works perfectly, it will list down all my friends.

I finally got it, apparently you cannot append inside the URL. you need to pass the fields in parameter inside SLRequest

NSURL *requestURL = [NSURL URLWithString:@"https://graph.facebook.com/me/friends"];

NSDictionary *param=[NSDictionary dictionaryWithObjectsAndKeys:@"picture,id,name,installed",@"fields", nil];

SLRequest *request = [SLRequest requestForServiceType:SLServiceTypeFacebook
                                        requestMethod:SLRequestMethodGET
                                                  URL:requestURL
                                           parameters:param];

First import Social, Account, SystemConfiguration framework in your project. Then use this code on your.m file

-(void)facebook
{
    self.accountStore = [[ACAccountStore alloc]init];
    ACAccountType *FBaccountType= [self.accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierFacebook];

    NSString *key = @"XXXXXXXXXXXXX";//get your key form creating new app in facebook app section
    NSDictionary *dictFB = [NSDictionary dictionaryWithObjectsAndKeys:key,ACFacebookAppIdKey,@[@"email"],ACFacebookPermissionsKey, nil];

    [self.accountStore requestAccessToAccountsWithType:FBaccountType options:dictFB completion:
     ^(BOOL granted, NSError *e) {
         if (granted)
         {
             NSArray *accounts = [self.accountStore accountsWithAccountType:FBaccountType];
             //it will always be the last object with single sign on
             self.facebookAccount = [accounts lastObject];


             ACAccountCredential *facebookCredential = [self.facebookAccount credential];
             NSString *accessToken = [facebookCredential oauthToken];
             NSLog(@"Facebook Access Token: %@", accessToken);


             NSLog(@"facebook account =%@",self.facebookAccount);

             [self get];

             [self getFBFriends];

             isFacebookAvailable = 1;
         } else
         {
             //Fail gracefully...
             NSLog(@"error getting permission yupeeeeeee %@",e);
             sleep(10);
             NSLog(@"awake from sleep");
             isFacebookAvailable = 0;

         }
     }];
   }

-(void)get
{

    NSURL *requestURL = [NSURL URLWithString:@"https://graph.facebook.com/me"];

    SLRequest *request = [SLRequest requestForServiceType:SLServiceTypeFacebook requestMethod:SLRequestMethodGET URL:requestURL parameters:nil];
    request.account = self.facebookAccount;

    [request performRequestWithHandler:^(NSData *data, NSHTTPURLResponse *response, NSError *error) {

        if(!error)

            NSDictionary *list =[NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&error];

            NSLog(@"Dictionary contains: %@", list );

            fbID = [NSString stringWithFormat:@"%@", [list objectForKey:@"id"]];
            globalFBID = fbID;

            gender = [NSString stringWithFormat:@"%@", [list objectForKey:@"gender"]];
            playerGender = [NSString stringWithFormat:@"%@", gender];
            NSLog(@"Gender : %@", playerGender);


            self.globalmailID   = [NSString stringWithFormat:@"%@",[list objectForKey:@"email"]];
            NSLog(@"global mail ID : %@",globalmailID);

              fbname = [NSString stringWithFormat:@"%@",[list objectForKey:@"name"]];
            NSLog(@"faceboooookkkk name %@",fbname);

            if([list objectForKey:@"error"]!=nil)
