如何使用 JSON-Framework 解析 iPhone SDK (XCode) 中的 JSON 对象 [英] How to parsing JSON object in iPhone SDK (XCode) using JSON-Framework

问题描述

我有这样的 JSON 对象:

I have JSON object like this :

{ "data":
  {"array":
    ["2",
       {"array":
          [
            {"clientId":"1","clientName":"Andy","job":"developer"},
            {"clientId":"2","clientName":"Peter","job":"carpenter"}
          ]
        }
     ]
   },
 "message":"MSG0001:Success",
 "status":"OK"
}

我想使用 JSON 框架获取数组 [0] 值 (2) 和数组 [1] 值(clientId、clientName、job).你知道怎么做吗?

I want to get the array[0] value (2) and array[1] value (clientId, clientName, job) using JSON-Framework. Do you have any idea how to do that?

推荐答案

假设您已遵循 安装 JSON-Framework 到您的项目的说明，这是您如何使用它(取自 此处的文档) :

Assuming you've followed the instructions to install JSON-Framework into your project, here's how you use it (taken from the docs here) :

// Parse the string into JSON
NSDictionary *json = [myString JSONValue];

// Get the objects you want, e.g. output the second item's client id
NSArray *items = [json valueForKeyPath:@"data.array"];
NSLog(@" client Id : %@", [[items objectAtIndex:1] objectForKey:@"clientId"]);
