问题
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

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 {

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)
