RestKit: Getting HTTP status code when a request fails

Question

I'm using RestKit in an iOS app and I need to have special handling for certain HTTP error codes. How can the the response HTTP status code be checked inside of request:didFailLoadWithError:? Is there some entry in the userInfo dictionary of the NSError?

I couldn't find anything in the RKRequestDelegate documentation.

Here's the interface for the delegate method:

- (void)request:(RKRequest *)request didFailLoadWithError:(NSError *)error

Answer 1

For people using the new version of RESTkit and objectManager, you can fetch the statuscode from the RKObjectRequestOperation:

operation.HTTPRequestOperation.response.statusCode

Answer 2

It turns out that didFailLoadWithError: is not called for HTTP errors. The request:didLoadResponse: method is still called for HTTP errors, so the response (and hence the status codes) are available.

Answer 3

The statusCode property found on RKResponse works for me:

- (void)objectLoader:(RKObjectLoader*)objectLoader didFailWithError:(NSError*)error 
{
    switch ([[objectLoader response] statusCode]) {
        case 409:
    ...

}
