saving email address Facebook + Parse (Swift) -

so i'm trying use parse + facebook login people in app, experiencing difficulty saving actual name/email address of user. i'm using facebook authentication now, , right user able login/reigster stores username encoded string (ie 6zahveaklzykna5weq29) instead of actual name. furthermore, no email address store (i using parse default "user" table).

here code

main view controller:

class homeviewcontroller: uiviewcontroller, pfloginviewcontrollerdelegate, pfsignupviewcontrollerdelegate {     @iboutlet weak var namelabel: uilabel!  var noteobjects: nsmutablearray! = nsmutablearray() let permissions = ["public_profile", "email"]  override func viewdidload() {     super.viewdidload()             utils.loginwithfacebook() }  override func viewdidappear(animated: bool) {     super.viewdidappear(animated)      if (pfuser.currentuser() == nil) {         // utils.loginwithfacebook()         let loginviewcontroller = myloginviewcontroller()         loginviewcontroller.signupcontroller = pfsignupviewcontroller()         //self.presentviewcontroller(loginviewcontroller, animated: true, completion: nil)          loginviewcontroller.fields = pfloginfields.facebook          loginviewcontroller.delegate = self          var signupviewcontroller = pfsignupviewcontroller()          signupviewcontroller.delegate = self          loginviewcontroller.signupcontroller = signupviewcontroller          self.presentviewcontroller(loginviewcontroller, animated: true, completion: nil)      }else {        //  utils.loginwithfacebook()         var username = pfuser.currentuser().username         namelabel.text = username         self.fetchallobjectsfromlocaldatastore()         self.fetchallobjects()     } }   func fetchallobjectsfromlocaldatastore() {      var query: pfquery = pfquery(classname: "note")      query.fromlocaldatastore()     query.wherekey("username", equalto: pfuser.currentuser().username)     query.findobjectsinbackgroundwithblock { (objects, error) -> void in          if (error == nil) {             var temp: nsarray = objects nsarray             self.noteobjects = temp.mutablecopy() as! nsmutablearray             //                self.tableview.reloaddata()         }else {             println(error.userinfo)         }     } }  func fetchallobjects() {      pfobject.unpinallobjectsinbackgroundwithblock(nil)      var query: pfquery = pfquery(classname: "note")     query.wherekey("username", equalto: pfuser.currentuser().username)     query.findobjectsinbackgroundwithblock { (objects, error) -> void in         if (error == nil) {             pfobject.pinallinbackground(objects, block: nil)             self.fetchallobjectsfromlocaldatastore()         }else {             println(error.userinfo)         }     } } func loginviewcontroller(logincontroller: pfloginviewcontroller!, shouldbeginloginwithusername username: string!, password: string!) -> bool {      if (!username.isempty || !password.isempty) {         return true     }else {         return false     } }  func loginviewcontroller(logincontroller: pfloginviewcontroller!, didloginuser user: pfuser!) {     self.dismissviewcontrolleranimated(true, completion: nil) }  func loginviewcontroller(logincontroller: pfloginviewcontroller!, didfailtologinwitherror error: nserror!) {     println("failed log in...") }  func signupviewcontroller(signupcontroller: pfsignupviewcontroller!, shouldbeginsignup info: [nsobject : anyobject]!) -> bool {     if let password = info?["password"] as? string {         // return password.utf16count >= 8         return count(password.utf16) >= 8     } else {         return false     } }  func signupviewcontroller(signupcontroller: pfsignupviewcontroller!, didsignupuser user: pfuser!) {     self.dismissviewcontrolleranimated(true, completion: nil) }  func signupviewcontroller(signupcontroller: pfsignupviewcontroller!, didfailtosignupwitherror error: nserror!) {     println("failed sign up...") }  func signupviewcontrollerdidcancelsignup(signupcontroller: pfsignupviewcontroller!) {     println("user dismissed sign up.") }  override func didreceivememorywarning() {     super.didreceivememorywarning()     // dispose of resources can recreated. }  // mark: - table view data source  override func prepareforsegue(segue: uistoryboardsegue, sender: anyobject?) {      //var upcoming: addnotetableviewcontroller = segue.destinationviewcontroller as! addnotetableviewcontroller     if (segue.identifier == "editnote") {      }  } } 

utils class have facebook login code

import foundation  class utils {   class func notloggedin() -> bool {     let user = pfuser.currentuser()     // here assume user must linked facebook     return user == nil || !pffacebookutils.islinkedwithuser(user) } class func loggedin() -> bool {     return !notloggedin() }   class func loginwithfacebook() {     pffacebookutils.loginwithpermissions(["public_profile", "user_friends", "email"]) {         (user: pfuser!, error: nserror!) -> void in         if user == nil {             nslog("the user cancelled facebook login (user nil)")         } else {             nslog("the user logged in facebook (user not nil)")             // here set acl installation             if let installation = pfinstallation.currentinstallation() {                 let acl = pfacl(user: pfuser.currentuser()) // user can write                 acl.setpublicreadaccess(true) // can read                 acl.setwriteaccess(true, forrolewithname: "admin") // admins can write                 installation.acl = acl                 //installation.saveeventually()             }             // username , fbid             utils.obtainusernameandfbid()         }     } }   class func obtainusernameandfbid() {     if notloggedin() {         return     }     let user = pfuser.currentuser() // won't nil because logged in     // return if have username , fbid (note check fbid because parse automatically fills in username random numbers)     if let fbid = user["fbid"] as? string {         if !fbid.isempty {             println("we have username , fbid -> return")             return         }     }     // request facebook     println("performing request fb username , idf...")     if let session = pffacebookutils.session() {         if session.isopen {             println("session open")             fbrequestconnection.startformewithcompletionhandler({ (connection: fbrequestconnection!, result: anyobject!, error: nserror!) -> void in                 println("done me request")                 if error != nil {                     println("facebook me request - error not nil :(")                 } else {                     println("facebook me request - error nil :)")                     println(result)                     // have 2 ways access result:                     // 1)                     println(result["name"])                     println(result["id"])                     println(result["email"])                     // 2)                     println(result.name)                     println(result.objectid)                     println(result.email)                     // save parse:                     pfuser.currentuser().username = result.email                     pfuser.currentuser().email = result.email                     pfuser.currentuser().setvalue(result.objectid, forkey: "fbid")                     pfuser.currentuser().setvalue(result.email, forkey: "email")                      //pfuser.currentuser().saveeventually()                     // use saveeventually if want sure save succeed                 }             })         }     } }  } 

the login screen user logs utilise facebook api won't give user's email. instead give access token 6zahveaklzykna5weq29 seeing. unless create custom web view not able store user's email. can store access token in nsuserdefaults or in case parse (i recommend using nsuserdefaults it's easier) , use make calls facebook api.
