I have used many hours on how to solve this issue. Im using Restkit 0.9.3 with Object Mapping 2.0. All data is in JSON. I can make GET, POST, PUT and DELETE operations corre
For version 0.10.0 this response error can be mapped as follows:
RKObjectMapping *errorMapping = [RKObjectMapping mappingForClass:[RKErrorMessage class]];
[errorMapping mapKeyPath:@"message" toAttribute:@"errorMessage"];
[[[RKObjectManager sharedManager] mappingProvider] setErrorMapping:errorMapping];
Requests that return an error will call the following delegate method:
- (void)objectLoader:(RKObjectLoader *)objectLoader didFailWithError:(NSError *)error {
NSArray *errorMessages = [[error userInfo] objectForKey:RKObjectMapperErrorObjectsKey];
RKErrorMessage *errorMessage = [errorMessages objectAtIndex:0]; // First and only object in your case.
NSString *message = [errorMessage errorMessage];
NSInteger code = [[objectLoader response] statusCode];
NSLog(@"ERROR: [%d] %@", code, message); // => ERROR: [401] Unauthorized
}
