ios - 无法强制将类型 'GraphRequestResult<GraphRequest>' 的值转换为类型 '[Any]'

Question

我正在使用新的 Facebook 图表请求:

let parameters = ["fields": "id, name, gender"]
                let nextrequest: GraphRequest = GraphRequest(graphPath: "me", parameters: parameters, accessToken: AccessToken.current, httpMethod: .GET)

                nextrequest.start({ (response: HTTPURLResponse?, result: GraphRequestResult<GraphRequest>) in
             //   }) { (connection: GraphRequestConnection! , result: AnyObject!, error: NSError!) -> Void in

                    print(result as [Any])

})

我很难解析它，我收到此错误:

无法将“GraphRequestResult”类型的值强制转换为“[Any]”类型

success(FacebookCore.GraphResponse(rawResponse: Optional({
    gender = male;
    id = 1128614937219535;
    name = "Rayan Slim";
})))

检查 GraphRequestResult 的签名，在您的情况下它是 (connection: GraphRequestConnection! , result: AnyObject!, error: NSError!) 也许 Swift 转换是创建 (连接:GraphRequestConnection!，结果:AnyObject？，错误:Error？)。即 NSError -> Error 并且它是可选。
