NSUrlConnectionDelegate - Getting http status codes

Question

in iOS, how can I receive the http status code (404,500 200 etc) for a response from a web server. I am assuming it's in the NSUrlConnectionDelegate.

Objective-C or Monotouch .NET answer ok.

Answer 1

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]; } 

Answer 2

NSHTTPURLResponse* urlResponse = nil; NSError *error = nil; responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&urlResponse error:&error]; 

The aSynchronous request should also have a way to get the NSHTTPURLResponse..

You get the status code like this:

int statusCode = [urlResponse statusCode]; int errorCode = error.code; 

In the case of some much used error codes (like 404) it will get put in the error but with a different code (401 will be -1012).
