i'm wondering how cover image user logged :

let requestparameters = ["fields": "id, email, first_name, last_name, name, gender, cover"]      let userdetails = fbsdkgraphrequest(graphpath: "me", parameters: requestparameters)      userdetails.startwithcompletionhandler { (connection, result, error:nserror!) -> void in          if(error != nil)         {             print("\(error.localizeddescription)")             return         }          if(result != nil)         {              let userid:string = result["id"] as! string             let userfirstname:string? = result["first_name"] as? string             let userlastname:string? = result["last_name"] as? string             let useremail:string? = result["email"] as? string             let username:string? = result["name"] as? string             let usergender:string? = result["gender"] as? string             let usercover:uiimage? = result["cover"] as? uiimage              print(requestparameters)             print(userdetails)             print(usercover)             print("\(useremail)")              let myuser:pfuser = pfuser.currentuser()!              // save first name             if(userfirstname != nil)             {                 myuser.setobject(userfirstname!, forkey: "firstnamecolumn")              }              //save last name             if(userlastname != nil)             {                 myuser.setobject(userlastname!, forkey: "lastnamecolumn")             }              // save email address             if(useremail != nil)             {                 myuser.setobject(useremail!, forkey: "email")             }              // save email address             if(usergender != nil)             {                 if (usergender == "male"){                 myuser.setobject("masculino", forkey: "gendercolumn")                 } else {                     myuser.setobject("feminino", forkey: "gendercolumn")                 }             }                  dispatch_async(dispatch_get_global_queue(dispatch_queue_priority_default, 0)) {                  // facebook profile picture                 let userprofile = "https://graph.facebook.com/" + userid + "/picture?type=large"                  let profilepictureurl = nsurl(string: userprofile)                  let profilepicturedata = nsdata(contentsofurl: profilepictureurl!)                  if(profilepicturedata != nil)                 {                     let profilefileobject = pffile(data:profilepicturedata!)                     myuser.setobject(profilefileobject!, forkey: "photousercolumn")                 }                   myuser.saveinbackgroundwithblock({ (success:bool, error:nserror?) -> void in                      if(success)                     {                         print("user details updated")                     }                  })                } 

this code not working cover image.

any ideas?

here's working example using fb sdk in swift. posted answer in other question because answer came first me on google thought it'll nice put here well.

i needed cover photo of page in graphpath used page id. parameter can changed fit users / events / etc...

let request = fbsdkgraphrequest(graphpath: "\\(page.id)?fields=cover", parameters: [   "access_token": "your_access_token" ], httpmethod: "get") request.startwithcompletionhandler({(connection , result , error) in   if ((error) != nil) {     print("error in fetching cover photo \\(page.id): \(error)", terminator: "")   }   else {     if let data = result["cover"] as? nsdictionary {       self.fetchimagefromurl(data["source"] as! string, cb: {(image: uiimage) -> void in         //do image       })     }   })  func fetchimagefromurl(url: string, cb: (uiimage) -> void) {   let urlobj = nsurl(string: url)!   dispatch_async(dispatch_get_global_queue(dispatch_queue_priority_default, 0)) {     let data = nsdata(contentsofurl: urlobj)     dispatch_async(dispatch_get_main_queue(), {       let image = uiimage(data: data!)!       cb(image)     });   } } 

p.s - i'm newbie in swift / ios code might not best. comments appreciated.
