How to do Facebook login in iOS >= 6 without Facebook sdk

Question

How to do Facebook login in iOS without Facebook sdk(i am supporting iOS6 and iOS7). My app is using Facebook login and user can share post on Facebook. Also i need to send the Facebook user id and auth token to my server.

Earlier I was supporting iOS 5 but now my iOS target >= iOS6 with Xcode 5.

For this i used Facebook SDK 3.11. From researching, i come to know that we can use SLComposeViewController, UIActivityViewController or SLRequest to share post. This will solve my sharing issue but how to do Facebook login and get auth token?

I tried SLRequest for Facebook login and SLComposeViewController for sharing, then is this good solution? (Here, i want to show Facebook native share dialog. So i haven't use SLRequest to share post because we have to make view for it.)

I referred this link. Is this the best solution to go forward?

only -if you have deployment target 6 -you have set your bundle id in setting, develelopers.facebook.com -you have set fb_app_id in your plist then

do like this without facebook sdk,

#import <Social/Social.h>
#import <Accounts/Accounts.h>
#define FB_APP_ID @"45666675444" // ur id here
@interface OGShareViewController ()
@property (strong, nonatomic) ACAccountStore *accountStore;
@property (strong, nonatomic) ACAccount *facebookAccount;
@property (strong, nonatomic) ACAccountType *facebookAccountType;
@end

-(void)viewDidLoad
{
[self getMyDetails];
}
- (void) getMyDetails {
    if (! _accountStore) {
        _accountStore = [[ACAccountStore alloc] init];
    }

    if (! _facebookAccountType) {
        _facebookAccountType = [_accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierFacebook];
    }

    NSDictionary *options = @{ ACFacebookAppIdKey: FB_APP_ID };

    [_accountStore requestAccessToAccountsWithType: _facebookAccountType
                                           options: options
                                        completion: ^(BOOL granted, NSError *error) {
                                            if (granted) {
                                                NSArray *accounts = [_accountStore accountsWithAccountType:_facebookAccountType];
                                                _facebookAccount = [accounts lastObject];

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

                                                SLRequest *request = [SLRequest requestForServiceType:SLServiceTypeFacebook
                                                                                        requestMethod:SLRequestMethodGET
                                                                                                  URL:url
                                                                                           parameters:nil];
                                                request.account = _facebookAccount;

                                                [request performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error) {
                                                    NSDictionary *responseDictionary = [NSJSONSerialization JSONObjectWithData:responseData
                                                                                                                       options:NSJSONReadingMutableContainers
                                                                                                                         error:nil];
                                                    NSLog(@"id: %@", responseDictionary[@"id"]);
                                                    NSLog(@"first_name: %@", responseDictionary[@"first_name"]);

                                                    NSLog(@"user name: %@", responseDictionary[@"username"]);

                                                    NSString *userPic  = [NSString stringWithFormat:@" http://graph.facebook.com/%@/picture?type=normal", responseDictionary[@"username"]
                                                                          ];
                                                      NSLog(@"profile pic link: %@", userPic);


                                                }];
