我有这行代码,我想提取“标题”键： @H_301_2@var title = jParams["title"] as! String

但它不会让我编译,如果我收到红色的错误消息：

Cannot subscript a value of a type AnyObject with an index of type String

当用println(jParams)在日志中显示jParams的内容时,我得到以下内容：

@H_301_2@INCOMING LIST PARAMETERS (jParameters) Optional({ title = "Example List"; values = ( { id = 1; name = "Line 1"; },{ id = 2; name = "Line 2"; },{ id = 3; name = "Line 3"; } ); })

我是Swift的新手,所以我不熟悉处理JSON来处理这些类型问题的细节.可能有什么不对？

@H_301_2@//jParams comes from a JSON server response var data = NSURLConnection.sendSynchronousRequest(request,returningResponse: nil,error: nil) if data != nil { var jdata = JSON(data: data!) var jParams=jdata["responseData"]["extraData"]["params"]
