如何在iOS5中将JSON数据对象发布到服务器？

我想使用 JSON数据类型使用POST方法将在iOS上创建的新对象发送到接收服务器.根据我对从iOS服务器接收数据的了解,苹果公司通过引入iOS 5简化了所有JSON处理.但与GETting JSON对象相比,POST这些并不是我能找到的任何地方. .

我尝试解决问题的第一步看起来如下：

//build an info object and convert to json
    NSDictionary *newDatasetInfo = [NSDictionary dictionaryWithObjectsAndKeys:name,@"name",language,@"language",nil];

    //convert object to data
    NSData* jsonData = [NSJSONSerialization dataWithJSONObject:newDatasetInfo options:kNilOptions error:&error];

    NSMutableuRLRequest *request = [[NSMutableuRLRequest alloc] init];
    [request setURL:someURLSetBefore];
    [request setHTTPMethod:@"POST"];
    // any other things to set in request? or working this way?

    [[NSURLConnection alloc] initWithRequest:request delegate:self];
    // What to do with NSURLConnection? Or how to send differently?

但我真的不知道如何使用POST方法将JSON对象发送到服务器.
有人可以帮帮我吗？

解决方法

我通过尝试一下来解决这个问题,这是我的代码：

//build an info object and convert to json
    NSDictionary *newDatasetInfo = [NSDictionary dictionaryWithObjectsAndKeys:name,nil];

    //convert object to data
    NSData* jsonData = [NSJSONSerialization dataWithJSONObject:newDatasetInfo options:kNilOptions error:&error];

    NSMutableuRLRequest *request = [[NSMutableuRLRequest alloc] init];
    [request setURL:someURLSetBefore];
    [request setHTTPMethod:@"POST"];
    [request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
    [request setValue:@"application/json" forHTTPHeaderField:@"Accept"];
    [request setHTTPBody:jsonData];

    // print json:
    NSLog(@"JSON summary: %@",[[Nsstring alloc] initWithData:jsonData
                                                     encoding:NSUTF8StringEncoding]);
    NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
    [connection start];
