Need to execute only one HTTP operation in AFNetworking and cancel the previous one

I use the AFNetworking framework and need to implement this logic to my web requests:

I see that AFHTTPRequestOperation is a NSOperation subclass, so I can write my own request manager but as I see there is AFHTTPRequestOperationManager in the framework. I only found that I can make a concurrency queue here so my requests will be executed one after another. Can I get the described behavior with AFHTTPRequestOperationManager? Thanks!

I will put this as an answer as well. So the idea is to do the following:

-create property for AFNetworkingOperation:

@property AFHTTPRequestOperation *post;

-in your initializer:

self.post = nil;

-in your function where you call request:

if(self.post){
    [post cancel];
}

-you need to assign self.post later:

self.post = [manager POST:nil parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
  self.post = nil;
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
   // error handling.
}];
