将JSON放入数组中 [英] Putting JSON into an Array

问题描述

在请求和JSON方面，我是一个菜鸟。在我的应用程序内部，我发送到服务器并获取东西，所以我当然可以使用它。我尝试查找不同的东西，但似乎没有一个看起来像我正在寻找的东西。所以我回到了似乎是JSON格式的东西。我想知道怎么做是把它放到NSMutable数组中。我获得此JSON的方式是使用AFNetworking的AFJSONRequestOperation。

I'm a noob when it comes to requests and JSON. Inside my app I send to the server and get back stuff so I can use it of course. I tried looking up different things but none really seem to be what I'm looking for. So I'm getting back what seems to be formatted JSON. What I want to know how to do is put it into a NSMutable array. The way I get this JSON is by using AFNetworking's AFJSONRequestOperation.

我的回答是这样的。

{
    id = 38;
    name = "St. Martin Hall";
},
    {
    id = 40;
    name = "Assumptions Commons";
},
    {
    id = 41;
    name = "Vickroy Hall";
},
    {
    id = 42;
    name = "St. Ann Hall";
},
    {
    id = 37;
    name = "Duquesne Towers";
}

推荐答案

如果您的JSON格式如{ mainKey：[{}，{}，...]}

if your JSON format like {"mainKey":[{},{},...]}

 NSError* error;
    NSDictionary* json = [NSJSONSerialization 
        JSONObjectWithData:responseData //1
         options:kNilOptions 
        error:&error];

    NSArray* dataArray = [json objectForKey:@"mainKey"]; //2

否则您的JSON格式如[{}，{}，...]

else your JSON format like [{},{},...]

NSError* error;
    NSArray* dataArray = [NSJSONSerialization 
        JSONObjectWithData:responseData //1
        options:kNilOptions 
        error:&error];

我认为你的格式是案例2：[]对象数组{}

I think your format is case 2: [] Array of Object {}
