试图访问嵌套的JSON数据

Question

我试图访问的JSON数据是嵌套相当深，但我只能得到嵌套的JSON，这似乎不够远。

这里是JSON数据：

目前，我只能访问最多在每个页面的插槽，但是我想打一个变量，让我确定slotID用于在每个时隙正在用过的。继承人我的意思：

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

if slotId == "runeSlotId: 1" { 

    println(slotId) 

} 
} 

此代码然而，不的工作，但是这就是我的意思是，当我说我想要一个变量，可以让我确定slotID用于在每个插槽。

这里是我的代码：

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) 



          } 
         } 

数据的代码被处理上面是我在顶部提供的JSON数据！

如果有人对我的意思感到困惑，请留下评论，我将编辑帖子！

slotId是一个字典数组，而不是一个字符串。也许一旦你得到slotId，打印之前，你做任何比较它进一步检查JSON。它看起来像是在正确的轨道上，但是对于嵌套字典，只需要一点时间来了解目前您正在查看的集合类型。把它分成小块，或者“一次剥下一层洋葱”，然后你就可以得到它。获取字典数组后，遍历每个项目以查看每个字典中的内容，然后可以根据需要获取该值。
