ios - 如何从不同变量的结果输出中获取电子邮件、姓名和图像

Question

 func getFBUserData(){
        if((FBSDKAccessToken.current()) != nil){
            FBSDKGraphRequest(graphPath: "me", parameters: ["fields": "id, name, first_name, last_name, picture.type(large), email"]).start(completionHandler: { (connection, result, error) -> Void in
                if (error == nil){
                    //everything works print the user data
                    print(result)                                    
                }
            })
        }
 }

输出是：

可选（{电子邮件=“[e-mail]”；“first_name”= Abhishek；id = 1760800260695143；“last_name”= Rajput；名称=“Abhishek Rajput”；图片={数据={高度=200；“is_silhouette " = 0; url = "platform-lookaside.fbsbx.com/platform/profilepic/…;; 宽度 = 200; }; }; })

你可以试试

if let res = result as? [String:Any] {
       print(res["first_name"])
       print(res["last_name"])
       print(res["name"])
       print(res["email"]) 
       if let picture = res["picture"] as? [String:Any] {                    
           if let data = picture["data"] as? [String:Any] {
                print(data["url"])
           } 
       }
}

你也可以使用Codable它
