推荐答案

是的，可以在委托方法-didRecieveResponse中获取状态码:

Yes, you can get status code in delegate method -didRecieveResponse:

- (void) connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response{
   NSHTTPURLResponse* httpResponse = (NSHTTPURLResponse*)response;
   int code = [httpResponse statusCode];
}
