iOS http post response to NSDictionary or NSArray

Question

我正在制作一个HTTP Post，我想知道如何将响应转换为NSDictionary，或NSArray。下面是我的代码:

NSString *post = [NSString stringWithFormat: @"SomeData=text", text];
        NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
        NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]];
        NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
        [request setURL:[NSURL URLWithString:@"https://www.my.site/receiver"]];
        [request setHTTPMethod:@"POST"];
        [request setValue:postLength forHTTPHeaderField:@"Content-Length"];
        [request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
        [request setHTTPBody:postData];
        NSURLResponse *response;
        NSError *err;
        NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&err];

编辑:

转换后的响应如下所示:

NSString *string = [[NSString alloc] initWithData:responseData encoding:NSASCIIStringEncoding];

您需要为此使用某种解析器。如果响应是XML格式，则可以使用NSXMLParser。在这里你可以找到如何使用它的教程。同样的概念也适用于任何其他类型的数据。你必须事先知道会发生什么，这样你才能正确地解析它。
