How to get response body in an AFNetworking failure block #AFNetworking

gistfile1.m

// I can never, ever remember how to do this, so here's how: 

failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSData *data= error.userInfo[AFNetworkingOperationFailingURLResponseDataErrorKey];
    NSString *failureResponse = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
    NSLog(@"Failure response: %@", failureResponse);
}

Can also do it like this, if server returns error in plaintext:

failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        NSLog(@"Response from server: %@", operation.responseString);
}
