How do i know if the success or failure block was executed in AFNetworking

I am working with AFNetworking. I created a class called MyRequest which extends NSObject. I created a method called requestForPost that 

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
NSDictionary *parameters = @{@"foo": variable1};
[manager POST:@"http://app.com/resources" parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSLog(@"JSON: %@", responseObject);


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

}];

When i am going to call a webservice, i pass the parameter dictionary to the above method so it'll execute the webservice.

How, am i suppose to know if the webservice request was a success or a failure. How am i supposed to pass the result back to the ViewController that i called the above webservice.

Create your custom network layer class to interact with server, where you can make custom handling of any request results/errors. And then use this class in your view controllers.

In this case you can change code in one place and can be sure that everything will be changed for all app, where you use this network layer class

Use the same way as AFNetworking do: use blocks. One for the success, one for the failure. Using this way in your UIViewController, you will know if your request was a success or failure, and the object returned.

In your API file:

- (void)yourAPIMethodWithSuccess:(void (^)(id responseObject))success failure:(void (^)(NSError *error))failure {
    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
    NSDictionary *parameters = @{@"foo": variable1};
    [manager POST:@"http://app.com/resources" parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {
        NSLog(@"JSON: %@", responseObject);
        success(responseObject);

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

In your controller:

- (void)fetchDataForRequest{
    YourAPIInstance yourAPIMethodWithSuccess:^(id expectedObject) {
        NSLog(@"Success: %@", expectedObject);
    } failure:^(NSError *error) {
        NSLog(@"Request failed: %@", [error localizedDescription]);
    }];
}
