nsdictionary获得指定key值

问题描述：

在nsdictionary中保存json解析的结果：

[plain]
{ 
 "statusCode":"200", 
"body":[ 
  { 
     "status":"success", 
     "remarks":null 
  } 
], 
 
"data":[ 
     "abcd":[ 
        { 
           "category":"a", 
           "title":"b", 
           "id":"24" 
        }, 
        { 
           "category":"c", 
           "title":"crd", 
           "id":"65" 
        }, 
        { 
           "category":"ds", 
           "title":"sd", 
           "id":"18" 
        } 
 
     ] 
  }, 
  { 
     "efgh":[ 
        { 
           "category":"ds", 
           "title":"sd", 
           "id":"18" 
        }, 
        { 
           "category":"sd", 
           "title":"sd", 
           "id":"1" 
        } 
 
                             ] 
  }, 
  { 
     "ijkl":[ 
        { 
           "category":"ds", 
           "title":"sd", 
           "id":"18" 
        }, 
        { 
           "category":"sd", 
           "title":"sd", 
           "id":"1" 
        } 
 
     ] 
  } 
 ] 
} 

{
 "statusCode":"200",
"body":[
  {
     "status":"success",
     "remarks":null
  }
],

"data":[
     "abcd":[
        {
           "category":"a",
           "title":"b",
           "id":"24"
        },
        {
           "category":"c",
           "title":"crd",
           "id":"65"
        },
        {
           "category":"ds",
           "title":"sd",
           "id":"18"
        }

     ]
  },
  {
     "efgh":[
        {
           "category":"ds",
           "title":"sd",
           "id":"18"
        },
        {
           "category":"sd",
           "title":"sd",
           "id":"1"
        }

                             ]
  },
  {
     "ijkl":[
        {
           "category":"ds",
           "title":"sd",
           "id":"18"
        },
        {
           "category":"sd",
           "title":"sd",
           "id":"1"
        }

     ]
  }
 ]
}
关键字@data的数据可以保存在数组中：

[plain]
NSMutableArray *getdata=[[NSMutableArray alloc]init]; 
getcat=[results objectForKey:@"data"]; 

NSMutableArray *getdata=[[NSMutableArray alloc]init];
getcat=[results objectForKey:@"data"];

补充：移动开发 , IOS ,

上一个：DTCoreText备忘
下一个：ARC forbids explicit message send of'retain'
