嗨我已更新到 swift 3并且收到错误：

Value of type ‘Any?’ has no member ‘valueForKey’

对于以下代码行：

let userName : NSString? = result.valueForKey("name") as? NSString
let facebookID : NSString? = result.valueForKey("id") as? NSString
let firstName : NSString? = result.valueForKey("first_name") as? NSString
let lastName : NSString? = result.valueForKey("last_name") as? NSString
let email : NSString? = result.valueForKey("email") as? NSString

这些错误的解释是什么？我将如何修复错误？

非常感谢！

完整代码：

if((FBSDKAccessToken.current()) != nil){
            FBSDKGraphRequest(graphPath: "me",parameters: ["fields": "id,name,first_name,last_name,email"]).start(completionHandler: { (connection,result,error) -> Void in
                if (error == nil){
                    
                    
                    let userName : NSString? = result.valueForKey("name") as? NSString
                    let facebookID : NSString? = result.valueForKey("id") as? NSString
                    let firstName : NSString? = result.valueForKey("first_name") as? NSString
                    let lastName : NSString? = result.valueForKey("last_name") as? NSString
                    let email : NSString? = result.valueForKey("email") as? NSString

回答：

FBSDKGraphRequest(graphPath: "me",error) -> Void in
                if (error == nil){
                    
                    let data:[String:AnyObject] = result as! [String : AnyObject]
                    
                    
                    let userName : NSString? = data["name"]! as? NSString
                    let facebookID : NSString? = data["id"]! as? NSString
                    let firstName : NSString? = data["first_name"]! as? NSString
                    let lastName : NSString? = data["last_name"]! as? NSString
                    let email : NSString? = data["email"]! as? NSString

虽然你找到了答案,但使用纯粹的快速方法而不是使用NSString更好,最好不要强制打开选项

FBSDKGraphRequest(graphPath: "me",error) -> Void in
            if (error == nil){
                  guard let data = result as? [String:Any] else { return }

                  let fbid = data["id"] 
                  let username = data["name"]  
                  let firstName = data["first_name"]
