How do I set basic authentication with RestKit 0.20.0? - restkit

Question

I'm trying to use RestKit to call an endpoint that requires basic authentication.
RKObjectMapping *mapping = [RKObjectMapping mappingForClass:[JSNCategory class]];
[mapping addAttributeMappingsFromDictionary:#{
#"id": #"catId",
#"name": #"name"
}];
NSIndexSet *statusCodes = RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful);
RKResponseDescriptor *responseDescriptor
= [RKResponseDescriptor responseDescriptorWithMapping:mapping
pathPattern:#"/api/v1/categories"
keyPath:nil
statusCodes:statusCodes];
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL
URLWithString:#"https://rest.example.com"]];
RKObjectRequestOperation *operation
= [[RKObjectRequestOperation alloc] initWithRequest:request
responseDescriptors:#[responseDescriptor]];
[operation setCompletionBlockWithSuccess:
^(RKObjectRequestOperation *operation, RKMappingResult *result) {
JSNCategory *cat = [result firstObject];
NSLog(#"Mapped the category: %#", cat);
} failure:^(RKObjectRequestOperation *operation, NSError *error) {
NSLog(#"Failed with error: %#", [error localizedDescription]);
}];

Answer 1

Using the objectmanager this would be something like:
NSURL* url = [[NSURL alloc]initWithString:#"http://rest.url.com"];
RKObjectManager* objectManager = [RKObjectManager managerWithBaseURL:url];
[objectManager.HTTPClient setAuthorizationHeaderWithUsername:#"username" password:#"password"];
Then, after setting the correct request/response you can use the objectmanager to do a get/post/etc:
[objectManager getObjectsAtPath:endpoint parameters:parameters success:
^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) {
// do something
}
failure:^(RKObjectRequestOperation *operation, NSError *error) {
// do something
}
];
