How to get status code in AFNetworking

Question

I have a method, for authorizing user. I need Basic authorization.

    NSString *url = [NSString stringWithFormat:@"%@/rest/api/person/auth", host];
    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
    [manager setRequestSerializer:[AFHTTPRequestSerializer serializer]];
    [manager.requestSerializer setAuthorizationHeaderFieldWithUsername:_loginField.text password:_passwordField.text];
    [manager setResponseSerializer:[AFJSONResponseSerializer serializer]];
    [manager GET:url parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
        [self parseResponseForUser:responseObject];
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        NSLog(@"Error %@ ",error);
    }];

The main problem here is determining error type. I may have error for authorization and error for network connection problem (host is not reachable). When login and password don't match criteria, failure block runs. For example, If I put wrong password and login I take this error message.:

Error Domain=NSCocoaErrorDomain Code=3840 "The operation couldn’t be completed. (Cocoa error 3840.)" (JSON text did not start with array or object and option to allow fragments not set.)

How should i catch error types?

Answer 1

Finally found answer, may be it will be helpful for someone. I just needed to use:

NSInteger statusCode = operation.response.statusCode;

And i can catch it like:

    [manager GET:url parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
        NSLog(@"response:%@", responseObject);
        [self parseResponseForUser:responseObject];
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        NSInteger statusCode = operation.response.statusCode;
        if(statusCode == 401) {
        } else if (statusCode == 404) {
        }
    }];
