Iphone 帮助我从json提要中获取每个元素？请

我有以下JSON数据：

 {
    "data":{
        "mat_149":{
            "id":"149",
            "title":"The closing of 40% profit within 9 month",
            "teaser":"profit within 9 months only which is equal to 52% annual profit",
            "body":" The auction was presented in a very high and commercial lands.\u000d\u000a",
            "files":{
                "911":{
                    "fid":"911",
                    "filename":"22.JPG",
                    "filepath":"http://mysite/files/22_0.JPG"
                }
            }
        },
        "mat_147":{
            "id":"147",
            "title":"Company launches the city ",
            "teaser":"demands for distinguished lands.",
            "body":" The area size is quare meters This is evident through projects and many other projects.\u000d\u000a\u000d\u000a",
            "files":{
                "906":{
                    "fid":"906",
                    "filename":"2D7z.jpg",
                    "filepath":"http://mysite/dlr/files/2D7Z.jpg"
                }
            }
        },
        "mat_link":"mysite.com/"
    }
}

我使用json框架对其进行如下解析：

NSString *response = [[NSString alloc] initWithData:receivedData encoding:NSASCIIStringEncoding] ;
SBJSON *parser = [[SBJSON alloc] init];  
NSDictionary *data = (NSDictionary *) [parser objectWithString:response error:nil];  
NSLog(@"Data : %@", [data valueForKey:@"data"] );

我得到数据：

NSLog(@"Data : %@", [data objectForKey:@"data"] );

我正在获取数据，但我应该如何获取“文件”项，如“fid”、“文件名”、“文件路径”。如何从“数据”n“文件”中获取每个元素并将其存储到某些NSString中

---

有人能指出我要做什么吗？请

它们都是子字典，不是吗， 只需尝试记录整个词典，就可以：

NSLog(@"%@", data);

然后你可以看到它的结构

要获取所有其他数据，需要创建一个数据模型来保存所有数据，该模型知道调用哪些键来获取特定字符串

或者你可以调用[数据所有键]； 通过迭代，获取您拥有模型对象的字典

例如：

//你在什么地方申报这个

NSArray *keys = [data allKeys]
for (NSString *key in [data allKeys]) {
NSDictionary *oneObject = [dictionary objectForKey:key];
MyObjectModel *object = [[MyObjectModel alloc] init];
object.id = [oneObject objectForKey:@"id"];
object.title = [oneObject objectForKey:@"title"];
//etc

//then you create another dict for files
}
