get responseObject on failure block AFNetworking 3.0

Question

how can I get the response string from failure block in AFNetworking 3.x,

In the 2.x version the way to do it was:

[manager GET:path parameters:param

I've found solution at GitHub:

@interface ResponseSerializer : AFJSONResponseSerializer
@end

@implementation ResponseSerializer

- (id)responseObjectForResponse:(NSURLResponse *)response
                       data:(NSData *)data
                      error:(NSError *__autoreleasing *)errorPointer
{
    id responseObject = [super responseObjectForResponse:response data:data error:errorPointer];
    if (*errorPointer) {
        NSError *error = *errorPointer;
        NSMutableDictionary *userInfo = [error.userInfo mutableCopy];
        userInfo[@"responseObject"] = responseObject;
        *errorPointer = [NSError errorWithDomain:error.domain code:error.code userInfo:[userInfo copy]];
    }
    return responseObject;
}

@end

And then assign it to your manager:

self.manager.responseSerializer = [ResponseSerializer serializer];
