使用AFNetworking解析JSON响应 [英] Parse JSON response with AFNetworking

问题描述

我在Objective-C中使用 AFNetworking 设置了一个JSON帖子，并使用以下代码将数据发送到服务器：

I've setup a JSON post with AFNetworking in Objective-C and am sending data to a server with the following code:

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
NSDictionary *parameters = @{@"name": deviceName, @"model": modelName, @"pin": pin};
manager.requestSerializer = [AFJSONRequestSerializer serializer];
[manager.requestSerializer setValue:@"Content-Type" forHTTPHeaderField:@"application/json"];
[manager POST:@"SENSORED_OUT_URL" parameters:parameters

success:^(AFHTTPRequestOperation *operation, id responseObject)
{
    NSLog(@"JSON: %@", responseObject);
}

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

我通过相同的请求收到信息，并希望将数据发送到的NSString 。如何使用 AFNetworking ？

I'm receiving information through the same request, and want to send the data to a NSString. How would I go about doing that with AFNetworking?

推荐答案

responseObject 是NSArray或NSDictionary。您可以在运行时使用 isKindOfClass检查：：

responseObject is either an NSArray or NSDictionary. You can check at runtime using isKindOfClass::

if ([responseObject isKindOfClass:[NSArray class]]) {
    NSArray *responseArray = responseObject;
    /* do something with responseArray */
} else if ([responseObject isKindOfClass:[NSDictionary class]]) {
    NSDictionary *responseDict = responseObject;
    /* do something with responseDict */
}

如果你真的需要JSON的字符串，可通过查看 operation.responseString 获得。

If you really need the string of the JSON, it's available by looking at operation.responseString.
