獲取數據後swift json類型數據解析

-2

我正在開發一個函數，它在Swift中調用NSURLRequest後接收到一些JSON。在解析結果後，我遇到了使用下標訪問不同數據值的問題。獲取數據後swift json類型數據解析

以下是檢索的JSON：

{"retCode":100,"retMsg":"Success","retData":{"usn":92,"id":"[email protected]","nickname":"ppigimi","profile_image":"..\/upload\/profile\/20150528172839.jpeg","language":"jp","join_channel_nm":"korfolk","cert_key":"696D6FB453DC141E5295E9D8E37B8DD0F1AFC8E34CE30B74551ED74A447AC564","cert_flag":"Y","join_date":"20150518155650","token":"3ea0a5fec1b55a5a23b5f1dc5c14b040dcd71eea"}}

以下是我的代碼。我不知道如何獲取retData中的值usn和token。

let task = NSURLSession.sharedSession().dataTaskWithRequest(request) { 
    data, response, error in 

    if error != nil { 
     println("error=\(error)") 
     return 
    } 

    // You can print out response object 
    println("response = \(response)") 

    // Print out response body 
    let responseString = NSString(data: data, encoding: NSUTF8StringEncoding) 
    println("responseString = \(responseString)") 

    //Let's convert response sent from a server side script to a NSDictionary object: 

    var err: NSError? 
    var myJSON = NSJSONSerialization.JSONObjectWithData(data, options: .MutableLeaves, error:&err) as? NSDictionary 


    if let parseJSON = myJSON as? [String: AnyObject] { 
     // Now we can access value of First Name by its key 
     var retCode = parseJSON["retCode"] as? Int 
     println("retCode: \(retCode)") 

     if let retData = parseJSON["retData"] as? [AnyObject] { 
      for data in retData { 
       /**let usn = data["usn"] 

       println("USN = \(usn)")**/ 
      } 
     } 

     if retCode == 100 { 
      //NSUserDefaults.standardUserDefaults().setValue("usn", forKey: String) 
     } 

     dispatch_async(dispatch_get_main_queue(), { 
      var myAlert = UIAlertController(title: "Alert", message: "AAAAAA", preferredStyle: UIAlertControllerStyle.Alert); 

      let okAction = UIAlertAction(title: "OK", style:UIAlertActionStyle.Default) { 
       action in 
       self.dismissViewControllerAnimated(true, completion: nil); 
      } 

      myAlert.addAction(okAction); 
      self.presentViewController(myAlert, animated: true, completion: nil); 
     }); 
    }  
} 

task.resume()

的問題是，你正在訪問retCode爲[AnyObject]。它不是Array，但實際上是一個JSON對象。您需要將其轉換爲Dictionay，例如[String : AnyObject]。

這意味着你的for循環，你正在訪問的數據可以看起來像下面：

if let retData = parseJSON["retData"] as? [String : AnyObject] { 
    for data in retData { 
     println("data is: \(data)") 
     /**let usn = data["usn"] 
     println("USN = \(usn)")**/ 
    } 
}
