使用NSJSONSerialization.JSONObjectWithData（）解析數據，但無法訪問數組只有字符串

Question

我已經下載了Json格式的數據。

{"name":"Shropshire Outage","nc_lead":"John Smith","dma":"11/111","username":"vwaghx1","status":"REOPENED","sapOrder":"12341245","ccsText":"123","nbPropAtRisk":12,"logs":[{"dateTime":"2016-04-07 20:02:42","valveStatusChangeDateTime":"2016-04-07 20:02:00","user":"vwaghx1","uid":null,"task":"CUSTPOORSUPPLIES","id_log":1489},{"dateTime":"2016-04-07 20:03:35","valveStatusChangeDateTime":"2016-04-07 20:02:00","user":"vwaghx1","uid":1238768765,"task":"PRESSURELOGGER","id_log":1490},{"dateTime":"2016-04-07 20:04:36","valveStatusChangeDateTime":"2016-04-07 20:02:00","user":"vwaghx1","uid":7692466478,"task":"CUSTSUPPLIESRESTOREDSOME","id_log":1491}],"id_event":601,"region":"Shropshire","trigger":"No Supply Call」,」valveOps":[{"dateTime":"2016-04-07 20:06:12","user":"vwaghx1","uid":7866756788,"x":678666,"y":723325,"description」:」Burst main downstream valve","id_valve_op":523},{"dateTime":"2016-04-07 20:05:31","user":"vwaghx1","uid":5674456470,"x":344534,"y":723433,"description":"Valve to separate both rezones","id_valve_op":522},{"dateTime":"2016-04-14 12:32:00","user":"vwaghx1","uid":1234512345,"x":123123,"y":123123,"description":"test","id_valve_op":541}],"images":[{"name":"After improvement.jpg","dateTimeCreated":"2016-04-08 14:10:30","contentType":"image/jpeg","caption":null,"uuid":null,"fileExtension":"jpeg","id_image":661},...]} 

然而，當我嘗試使用下面的代碼來解析它，我只能訪問字符串值，如「名」，「nc_lead」，「區域」等

if let json = try NSJSONSerialization.JSONObjectWithData(data!, options:.AllowFragments) as? Array<Dictionary<String, AnyObject>> { 
    for item in json { 
     if let dict = item as? Dictionary<String, AnyObject> { 
      if let nameStr = dict["name"] as? String { 
       incidentList.valueStr = nameStr 
      } 
      if let codeStr = dict["dma"] as? String { 
       incidentList.valueStr = codeStr 
      } 
      if let region = dict[「region」] as? String { 
       incidentList.valueStr = region 
      } 
      if let ncLead = dict[「nc_lead」] as? String { 
       incidentList.valueStr = ncLead 
      } 

我需要訪問像「logs」，「images」和「valveOps」這樣的組值，這些值在數組中有自己的字符串值。 如何更改我的代碼，以便我可以像現在一樣訪問字符串，並將這些組加載到數組中？

你可以這樣試試，先聲明3個數組。

var logArr: [[String: AnyObject]] = [[String: AnyObject]]() 
var imageArr: [[String: AnyObject]] = [[String: AnyObject]]() 
var valveArr: [[String: AnyObject]] = [[String: AnyObject]]() 

現在使用這個數組，你在哪裏得到響應

if let json = try NSJSONSerialization.JSONObjectWithData(data!, options:.AllowFragments) as? Array<Dictionary<String, AnyObject>> { 
for item in json { 
    if let dict = item as? Dictionary<String, AnyObject> { 
     if let nameStr = dict["name"] as? String { 
      incidentList.valueStr = nameStr 
     } 
     if let codeStr = dict["dma"] as? String { 
      incidentList.valueStr = codeStr 
     } 
     if let region = dict["region"] as? String { 
      incidentList.valueStr = region 
     } 
     if let ncLead = dict["nc_lead"] as? String { 
      incidentList.valueStr = ncLead 
     } 
     if let logs = dict["logs"] as? [[String: AnyObject]] { 
      self.logArr = logs 
     } 
     if let valveOps = dict["valveOps"] as? [[String: AnyObject]] { 
      self.valveArr = valveOps 
     } 
     if let images = dict["images"] as? [[String: AnyObject]] { 
      self.imageArr = images 
     }
