ios - AFNetworking (iOS) - 响应不是 NSDictionary

Question

我知道我的请求格式正确，但我从网络服务获得的响应不是 NSDictionary。

1. 为什么它不是 NSDictionary？

2. 如何判断“responseObject”是哪种对象？

   AFHTTPRequestOperation *operation = [[AFParseAPIClient sharedClient]  HTTPRequestOperationWithRequest:request success:^(AFHTTPRequestOperation *operation, id responseObject) {
       if ([responseObject isKindOfClass:[NSDictionary class]]) {
           NSLog(@"Response for %@: %@", className, responseObject);
           [self writeJSONResponse:responseObject toDiskForClassWithName:className];
       }else{
           //NSLog(@"Response NOT NSDictionary: %@", [responseObject class]);
           NSString *str = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
           NSLog(@"str: %@", str);
       }
   } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
       NSLog(@"Request for class %@ failed with error: %@", className, error);
   }];
   

这是我得到的:

//Response NOT NSDictionary: <7b227265 73756c74 73223a5b 7b22636f ...>

编辑:这是我得到的结果:

str: {"results":[{"desc":"My description.","device_iPad":true,"device_iPhone":true,"createdAt":"2012-09-05T18:36:11.431Z","updatedAt":"2012-09-05T22:00:52.199Z"}]}

只需在创建操作后添加这行代码

operation.responseSerializer = [AFJSONResponseSerializer 序列化器];
