如何从下面的格式（NDictionary）访问值？

Question

我正在使用googlematrix api调用，在下面我提到了响应。

这里是我的代码

let jsonObjects=responseObject as! NSDictionary 
    var data = jsonObjects.data(using: .utf8)! 
    if let parsedData = try? JSONSerialization.jsonObject(with: data) as! [String:Any] { 
    let language = parsedData["rows"] as! [String:Any] 
    print(language) 
    let field = language["elements"] as! [[String:Any]] 
    let name = field["distance"]! 
    let text = field["text"]! 
    print(text) // ==> Test1 
} 

我需要从以下格式访问文本和值在swift3.0

{ 
     "destination_addresses" : [ "Chennai, Tamil Nadu, India" ], 
     "origin_addresses" : [ "Madurai, Tamil Nadu, India" ], 
     "rows" : [ 
      { 
      "elements" : [ 
       { 
        "distance" : { 
         "text" : "488 km", 
         "value" : 487721 
        }, 
        "duration" : { 
         "text" : "8 hours 32 mins", 
         "value" : 30690 
        }, 
        "status" : "OK" 
       } 
      ] 
      } 
     ], 
     "status" : "OK" 
    }

试试这个代码：

let responseObject : NSDictionary! = YOUR RESPONSE 

     let jsonObjects = responseObject as NSDictionary 
     let array : NSArray! = jsonObjects.object(forKey: "rows") as! NSArray! 

     for elmnt in array 
     { 
      let element = elmnt as! NSDictionary 
      let ary_Element : NSArray! = element.object(forKey: "elements") as! NSArray! 

      for data in ary_Element 
      { 
       let mDict = data as! NSDictionary 

       let dict_Distance = mDict.value(forKey: "distance") as! NSDictionary 
       let dict_Duration = mDict.value(forKey: "duration") as! NSDictionary 

       print(dict_Distance.value(forKey: "text")) 
       print(dict_Distance.value(forKey: "value")) 
       print(dict_Duration.value(forKey: "text")) 
       print(dict_Duration.value(forKey: "value")) 
      } 
     }
