Facebook login via social framework in ios

Question

I'm new with iOS development. I have to integrate Facebook login in my iOS app, as user logs in it fetches all the info and navigates it to home screen. I have done this via Facebook latest SDK but I want it to be done via social framework. I have gone through lots of online stuff and also have found examples where they are sharing(posting) content on Facebook page(Wall) via social framework but not Facebook login exactly. Anyone please help, let me know if Facebook login is possible via social framework or i have to stick to SDK. Thanks in Advance

Import Social and Acount Framwork

put this code in your .m file

-(void)facebook

    self.accountStore = [[ACAccountStore alloc]init];

    NSString *key = @"451805654875339";
    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];

Swift 3 Version of solution @reena

@IBAction func loginButtonPressed(_ sender: UIButton) {

    var facebookAccount: ACAccount?
    let options:[String : Any] = [ACFacebookAppIdKey: "YOUR_FACEBOOK_API_KEY", ACFacebookPermissionsKey: ["email"],ACFacebookAudienceKey:ACFacebookAudienceFriends]

    let accountStore = ACAccountStore()

    let facebookAccountType = accountStore.accountType(withAccountTypeIdentifier: ACAccountTypeIdentifierFacebook)

    accountStore.requestAccessToAccounts(with: facebookAccountType, options: options) { (granted:Bool, error:Error?) in
        if granted{
            let accounts = accountStore.accounts(with: facebookAccountType)
            facebookAccount = accounts?.last as? ACAccount

            let dict:NSDictionary = facebookAccount!.dictionaryWithValues(forKeys: ["properties"]) as NSDictionary
            let properties:NSDictionary = dict["properties"] as! NSDictionary

            print("facebook Response is-->:%@",properties)
        }
        else {
            if let err = error as? NSError, err.code == Int(ACErrorAccountNotFound.rawValue) {
                DispatchQueue.main.async {
                    self.displayAlert("There is no Facebook accounts configured. you can add or created a Facebook account in your settings.")
                }
            } else {
                DispatchQueue.main.async {
                    self.displayAlert("Permission not granted For Your Application")
                }

Facebook login using Accounts and social framework (swift)

var facebookAccount: ACAccount?

        let options: [NSObject : AnyObject] = [ACFacebookAppIdKey: "YOUR_FACEBOOK_API_KEY", ACFacebookPermissionsKey: ["publish_stream","publish_actions"],ACFacebookAudienceKey:ACFacebookAudienceFriends]
        let accountStore = ACAccountStore()
        let facebookAccountType = accountStore.accountTypeWithAccountTypeIdentifier(ACAccountTypeIdentifierFacebook)

            accountStore.requestAccessToAccountsWithType(facebookAccountType, options: options) { (granted, error) -> Void in
                if granted
                {
                    let accounts = accountStore.accountsWithAccountType(facebookAccountType)
                    self.facebookAccount = accounts.last as? ACAccount
                    let accountsArray=accountStore.accountsWithAccountType(facebookAccountType) as NSArray

                    self.facebookAccount=accountsArray.lastObject as? ACAccount
                    var dict:NSDictionary
                    dict=NSDictionary()

                    dict=self.facebookAccount!.dictionaryWithValuesForKeys(["properties"])
                    let properties:NSDictionary=dict["properties"] as! NSDictionary
                    print("facebook Response is-->:%@",properties)

                        dispatch_async(dispatch_get_main_queue(), { () -> Void in
                            self.displayAlert("There is no Facebook accounts configured. you can add or created a Facebook account in your settings.")
