swift 3：输入“Any？”没有下标成员 [英] swift 3: Type 'Any?' has no subscript members

问题描述

键入'Any？'没有下标成员

结果的错误点....这只发生在我转换成swift 3 ... anybody ????

  let nextrequest：FBSDKGraphRequest = FBSDKGraphRequest（graphPath：me / friends，参数：[fields：name，id，gender]，httpMethod ：GET）
 nextrequest.start {（连接，结果，错误） - >空的
 guard let listOfFriends = result [data] as？ [AnyObject] else {
 return 
} 
} 
} 
  

解决方案

尝试这个

  let nextrequest：FBSDKGraphRequest = FBSDKGraphRequest（graphPath：我/朋友，参数：[fields：name，id，gender]，httpMethod：GET）
 nextrequest.start {（connection，result，error） - >空虚在
 guard让result = result为？ [String：[AnyObject]]，让listOfFriends = result [data] else {
 return 
} 
} 
} 
  

I keep getting this error for my graph requests??

Type 'Any?' has no subscript members

the error points at result.... this only happened when I converted to swift 3... anybody????

 let nextrequest: FBSDKGraphRequest = FBSDKGraphRequest(graphPath: "me/friends", parameters: ["fields": "name, id, gender"], httpMethod: "GET")
            nextrequest.start { (connection, result, error) -> Void in
                guard let listOfFriends = result["data"] as? [AnyObject] else {
                    return
                }
            }
        }

解决方案

Try this

let nextrequest: FBSDKGraphRequest = FBSDKGraphRequest(graphPath:"me/friends", parameters: ["fields": "name, id, gender"], httpMethod: "GET")
    nextrequest.start { (connection, result, error) -> Void in
         guard let result = result as? [String:[AnyObject]], let listOfFriends = result["data"]  else {
        return
    }
  }
}
