ios - 如何打印来自简单有效的 POST 方法的响应

Question

我有一个看起来像这样的 post 方法:

NSString *totalPostURL = [NSString stringWithFormat:@"%@registerDevice",self.textUrl];

NSMutableURLRequest *request = [NSMutableURLRequest
                                    requestWithURL:[NSURL URLWithString:totalPostURL]];


NSError *error;
NSData *postData = [NSJSONSerialization dataWithJSONObject:self.finalDict options:0 error:&error];
[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[request setHTTPMethod:@"POST"];
[request setHTTPBody:postData];
NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];

代码工作正常，但我不知道如何打印这篇文章的回复。欢迎提出任何建议，因为我是 iOS 开发的新手。

您可以打印如下响应:

NSData *returnData = [ NSURLConnection sendSynchronousRequest: request returningResponse: nil error: nil ];
NSString *returnString = [[NSString alloc] initWithData:returnData encoding: NSUTF8StringEncoding];

NSLog(@"Response:%@",returnString);

但是请记住，作为新手，不要忘记阅读调用 web 服务的教程。 Interacting with webservices.
