Question

我试图非常深入地访问嵌套的JSON数据，但我只能在嵌套的JSON中获得这么远，这似乎还不够。< / p>

这是JSON数据：

目前，我只能访问每个页面中的插槽，但我想创建一个变量，让我确定每个插槽中的哪个slotId正在使用。这是我的意思：

let slotId = slot["runeSlotId"] as? [[String : AnyObject]] {

 if slotId == "runeSlotId: 1" {

     println(slotId)

 }
}

然而，这段代码不有效，但当我说我想创建一个变量让我确定每个插槽中的哪个slotId时，这就是我的意思。

这是我的代码：

 if let json = NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions.MutableContainers, error: &err) as? NSDictionary, let include = json.objectForKey("\(self.idNumber)") as? NSDictionary {

                    println("json working")

                    //println(json)

                    if let pages = include["pages"] as? [[String : AnyObject]] {


                        println("stat summary working")


                        for page in pages {

                           //println(page)

                            for slot in page {

                                //println(slot)

                                //this is where it determines each slot and where I would like to put the code below but it results in an error

                                /*if let slotId = slot["runeSlotId"] as? [[String : AnyObject]] {

                                    if slotId == "runeSlotId: 1" {

                                        println(slotId)

                                    }
                                }*/
                            }


                            if let name = page["name"] as? String {

                                    //println(name)

                                    self.runeNamesArray.append(name)
                                    //println(self.runeNamesArray)

                            }

                            if let id = page["id"] as? NSNumber {

                               // println(id)



                            }
                        }

上面代码中处理的数据是我在顶部提供的JSON数据！

如果有人对我的意思感到困惑，请留言，我会编辑帖子！

slotId是一个字典数组，而不是字符串。也许一旦你得到slotId，在你对它进行任何比较之前打印它以进一步检查JSON。看起来你走在正确的轨道上，但是使用嵌套的词典，只需要一点时间来了解你目前正在看什么类型的收藏品。将它分解成小块，或者“一次剥去一层洋葱”，你就可以得到它。获得字典数组后，遍历每个项目以查看每个字典中的内容，然后您可以获得所需键的值。
