NSURLResponse – How to get status code?

Cast an instance of NSHTTPURLResponse from the response and use its statusCode method.

[NSURLConnection sendAsynchronousRequest:myRequest queue:queue completionHandler:^(NSURLResponse *response, NSData *data, NSError *error) {
    NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse *) response;
    NSLog(@"response status code: %ld", (long)[httpResponse statusCode]);
    // do stuff
}];
