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)     });   } }
