Question

我正在尝试在我的应用中登录fb后检索电子邮件ID。但是当我尝试从结果中获取值时，我收到错误。

错误是：Type 'Any?' has no subscript members。

func fetchProfile()
{
    print("Fetch Profile")
    let parameters = ["fields": "email, first_name, last_name,  picture.type(large)"]
    FBSDKGraphRequest(graphPath: "me", parameters: parameters).start { (connection, result, error) in

        let email = result["email"] as? String  //Type 'Any?' has no subscript members error occurs here.
    }
}

Answer 1

更改此

 let email = result["email"] as? String

进入

  guard let resultNew = result as? [String:Any] 

 let email = resultNew["email"]  as! String

完整答案

let parameters = ["fields": "email, first_name, last_name,  picture.type(large)"]
    FBSDKGraphRequest(graphPath: "me", parameters: parameters).start { (connection, result, error) in

        guard let resultNew = result as? [String:Any] 

       let email = resultNew["email"]  as! String
    }
