-1

这是一个样本json代码，我必须在我的项目中实现，请告诉我如何编写代码。我多次写代码。这根本不是工作。所以我希望全部例子。在swift中解析json对象内的对象

在这里我可以看到，首先有一个对象，接下来有一个多个对象，最后是一个对象内的数组。请参阅详细信息...

你想不清楚是什么。 –

@RinkiNegi基本上我有一个对象，其中有另一个名为“数据”的数组。我只需要解析数据数组 –

请写下你写的邮政编码和你得到的错误 – anhtu

关键products的值是一个字典，而不是一个数组，guard评估退出的错误范围：

guard let products = json["products"] as? [String: Any] else { return }

产品数量是正确的，但删除括号并在as后面加上感叹号（我不知道为什么编译器建议括号）：

self.product_count = json["product_count"] as! Int

现在得到的项目（再次用一个后卫）：

guard let items = products["data"] as? [[String:Any]] else { return }

和迭代直通环路

for item in items { 
    let oProduct2Datas = Product2Data() 

    oProduct2Datas.id = item["id"] as? Int 
    oProduct2Datas.name = item["name"] as? String 
...

我必须为next_page_url编写代码 –

它在'products'级别：'let nextPageURL = products [“next_page_url”] as？字符串' – vadian

你能帮我回答这个问题吗？我想通过点击按钮来检测tableview单元格中的一个按钮。这里是链接https://stackoverflow.com/questions/48970198/how-to-detect-one-button-in-tableview-cell?noredirect=1#comment84948065_48970198 –

试试这个：

func demo() 
{ 
let str : String = "urlString" 
let url = NSURL(string:str) 
let request = NSMutableURLRequest(URL: url!) 
request.HTTPMethod = "POST" 
request.setValue("application/json", forHTTPHeaderField: "Content-Type") 
Alamofire.request(request) 
    .responseString { response in 
     switch (response.result) { 
     case .Success(let JSON): 
      let data = JSON.dataUsingEncoding(NSUTF8StringEncoding)! 
      do { 
       let responseString = try NSJSONSerialization.JSONObjectWithData(data, options: []) as? [String:AnyObject] 
       print(responseString!) 
       self.prodName = [] 
       let dict = responseString!["products"] as! NSDictionary 
let arr = dict["data"] as NSArray 
       for j in 0..<arr.count{ 
        let dic = arr[j] as! NSMutableDictionary 
        self.prodName.addObject(dic.valueForKey("name")!) 

       } 
      } catch _ as NSError { 
       //print(error) 
      } 
      break 
     case .Failure: 
      print("FAILURE") 
      break 
     } 
}}

是否有可能没有Alamofire？ –

与sharedSession相同的代码也可以做 –

可以不用alamofire重新编码请 –

在swift中解析json对象内的对象
