如何斯威夫特获得的Facebook用户ID，电子邮件，picture.type（大）3

你好，我尝试从Facebook SDK获得用户id, email, picture.type(large),updated_time，我的成功让所有的人，但我没有得到图片给我如何斯威夫特获得的Facebook用户ID，电子邮件，picture.type（大）3

错误无法调用非函数类型的值'任何？！'

我的清晰代码如下。

import UIKit 
    import Foundation 

    class LoginViewController : UIViewController, FBSDKLoginButtonDelegate { 
     private var fromLogin = [Login]() 
     @IBOutlet weak var loginButton : FBSDKLoginButton! 

     override func viewDidLoad() { 
      super.viewDidLoad() 
      // Check Session 
      if let token = FBSDKAccessToken.current(){ 
       print(token.tokenString! as Any) 
       self.fetchProfile() 
      } 

      loginButton.delegate = self 
      loginButton.readPermissions = ["email", "public_profile"] 
    } 

    // Get Profile 
    func fetchProfile() { 
     print("fetch profile") 

     // Create facebook graph with fields 
     FBSDKGraphRequest(graphPath: "me", parameters: ["fields":"id, name, email, picture.type(large), updated_time"]).start { (connection, result, error) in 

      // check error 
      if error != nil { 
       // error happen 
       print("Failed to start graph request: \(error?.localizedDescription)") 
       return 
      } 

      if let userDict = result as? NSDictionary { 
       let name = userDict["name"] as? String 
       let id = userDict["id"] as? String 
       let email = userDict["email"] as? String 

       // HERE GIVES ERROR I DIDNT GET PICTURE WITH STRING  
       let userPicture = userDict.objectForKey("picture")?.objectForKey("data")?.objectForKey("url") as String 

       print(userPicture) 
       print(name as Any) 
       print(id as Any) 
       print(email as Any) 
     } 
    } 
} 

// Delegate Method 
func loginButton(_ loginButton: FBSDKLoginButton!, didCompleteWith result: FBSDKLoginManagerLoginResult!, error: Error!){ 
    // check error 
    if error != nil { 
     // error happen 
     print(error?.localizedDescription as Any) 
     return 
    } 

    print("Successfull login in with facebook...") 
    fetchProfile() 
} 

func loginButtonDidLogOut(_ loginButton: FBSDKLoginButton!){ 
    print("Log Out") 
}

该行给出错误;

让userPicture = userDict.objectForKey（ “图片”）？objectForKey（ “数据”）？objectForKey（ “URL”）作为字符串

另外图片浏览对象JSON数据示例;

picture =  { 
     data =   { 
      "is_silhouette" = 0; 
      url = "https://scontent.xx.fbcdn.net/v/t1.0-1/p200x200/14067524_9513823423422249533237851_n.jpg?oh=88eb9b80abbb2342346c01de298&oe=58C5138B"; 
     }; 
    };

进出口使用Xcode 8.1和Swift 3.0

谢谢！

试试下面的答案 – User511

@ User511我的代码工作只需要获得图片真实串码 – SwiftDeveloper

它有完整的代码。它为我工作。 – User511

这需要简单的分析。 “图片” 是字典，所以是 “数据”。所以像下面为你工作

guard let userDict = result as? [String:Any] else { return } 

let name = userDict["name"] as? String 
let id = userDict["id"] as? String 
let email = userDict["email"] as? String 

if let picture = userDict["picture"] as? [String:Any] , 
    let imgData = picture["data"] as? [String:Any] , 
    let imgUrl = imgData["url"] as? String { 
     print(imgUrl) 
}

@El Captain v2.0谢谢你在Xcode 8.1和Swift 3.0上完美工作 – SwiftDeveloper

很高兴帮助:) –

替换此

FBSDKGraphRequest(graphPath: "me", parameters: ["fields":"id, name, email, picture.type(large), updated_time"]).start { (connection, result, error) in

与

FBSDKGraphRequest(graphPath: "me", parameters: ["fields":"id, name, email, picture.width(500).height(500), updated_time"]).start { (connection, result, error) in

然后检查这个

if let imageUrl = ((dictData.value(forKey: "picture") as? NSDictionary)?.value(forKey: "data") as? NSDictionary)?.value(forKey: "url") as? NSString 
            { 
             Facebook.imagesArr.add(imageUrl) 
             print("Pictureasd:",Facebook.imagesArr) 
            }

func loginButton(_ loginButton: FBSDKLoginButton!, didCompleteWith result: FBSDKLoginManagerLoginResult!, error: Error!) 
    { 
     FBSDKGraphRequest.init(graphPath: "me", parameters: ["fields":"first_name, last_name, picture.type(large)"]).start { (connection, result, error) -> Void in 

      let strFirstName: String = (result.object(forKey: "first_name") as? String)! 
      let strLastName: String = (result.object(forKey: "last_name") as? String)! 
      let strPictureURL: String = (result.object(forKey: "picture")?.object(forKey: "data")?.object(forKey: "url") as? String)! 

      self.lblName.text = "Welcome, \(strFirstName) \(strLastName)" 
      self.ivUserProfileImage.image = UIImage(data: try! Data(contentsOf: URL(string: strPictureURL)!)) 
     } 
    }
