RESTKit POST Request Tutorial

Question

I would like to know if there is a specific tutorial on how to do a POST request with RESTKit. I have looked at some tutorials but I haven't found any that say, "This is exactly how you do a POST request with RESTKit." Help is much appreciated.

Answer 1

Assuming you already have a mapped model, you can simply perform this:

First, set a requestDescriptor with the inverseMapping of your responseDescriptor, assuming you have one with your mapping.

//This is used for mapping responses, you already should have one of this. PS:[Data mapping] is a method that returns an RKObjectMapping for my model. You should create yours or use a previous created one
RKResponseDescriptor *responseDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:[Data mapping] pathPattern:nil keyPath:@"data" statusCodes:statusCodeSet];
[[RKObjectManager sharedInstance] addResponseDescriptor:responseDescriptor];

//Inverse mapping, to perform a POST
RKRequestDescriptor *requestDescriptor = [RKRequestDescriptor requestDescriptorWithMapping:[[Data mapping] inverseMapping]  objectClass:[Data class] rootKeyPath:nil];
[[RKObjectManager sharedInstance] addRequestDescriptor:requestDescriptor];

After that, to perform a POST, just simply call the method below. Restkit will get the instance that you are trying to post, serialize it and send to the path chosen.

[[RKObjectManager sharedInstance] postObject:instanceOfYourModel path:yourPathHere parameters:nil success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) {
    NSLog(@"Success");

} failure:^(RKObjectRequestOperation *operation, NSError *error) {
    NSLog(@"Error");
}];

If you don't have a mapped model, let me know so we can try something else.
