如何将json数组按位置保存到数组中？

Question

我在尝试阅读以下 json（示例）数组时遇到了困难：

[
 {
  "id":"173",
  "user":"44",
  "value":"100.00"
 },
 {
  "id":"158",
  "user":"44",
  "value":"1000.00"
 }
]

代码：

NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
NSDictionary * parameters = @{@"entitty":self.entity};
NSString *url = [[defaults objectForKey:@"url_api"] stringByAppendingString:@"/blabla"];

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer = [AFHTTPResponseSerializer serializer];

[manager POST:url parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {

    NSDictionary* json_string = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
    NSDictionary *json_dict = (NSDictionary *)json_string;

//it does not fail but is copying the same information as json_dict and what I actually need is to save position by position
    NSArray * array = json_dict;

    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        NSLog(@"%@", error);

}];

请帮忙。

使用 AFJSONResponseSerializer 而不是 AFHTTPResponseSerializer，您将在 responseObject.

中收到已解析的 NSArray 或 NSDictionary
