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

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?

Answer 1

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(#"last_name: %#", responseDictionary[#"last_name"]);
NSLog(#"gender: %#", responseDictionary[#"gender"]);
NSLog(#"city: %#", responseDictionary[#"location"][#"name"]);
NSLog(#"user name: %#", responseDictionary[#"username"]);
// http://graph.facebook.com/facebook/picture?type=normal
NSString *userPic = [NSString stringWithFormat:#" http://graph.facebook.com/%#/picture?type=normal", responseDictionary[#"username"]
];
NSLog(#"profile pic link: %#", userPic);
}];
} else {
[self showAlert:#"Facebook access for this app has been denied. Please edit Facebook permissions in Settings."];
}
}];
}
- (void) showAlert:(NSString*) msg {
dispatch_async(dispatch_get_main_queue(), ^(void) {
UIAlertView *alertView = [[UIAlertView alloc]
initWithTitle:#"WARNING"
message:msg
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[alertView show];
});
}
