AFNetworking 2: How to cancel a AFHTTPRequestOperationManager request?

Question

I migrated my networking functionality from AFNetworking to AFNetworking v2 and instead of AFHttpClient I am using AFHTTPRequestOperationManager to support iOS6 as well.

My issue is that while in AFHttpClient there was the functionality to cancel a pending request using the

- (void)cancelAllHTTPOperationsWithMethod:(NSString *)method path:(NSString *)path;

method, in the AFHTTPRequestOperationManager there is no such obvious method.

What I've done up to now is subclassing AFHTTPRequestOperationManager and declaring an iVar

AFHTTPRequestOperation *_currentRequest;

When I make a request the code is something like

- (void)GetSomething:(NSInteger)ID success:(void (^)(MyResponse *))success failure:(void (^)(NSError *))failure
{
    _currentRequest = [self GET:@"api/something" parameters:@{@"ID": [NSNumber numberWithInteger:ID]} success:^(AFHTTPRequestOperation *operation, id responseObject) {
        MyResponse *response = [MyResponse responseFromDictionary:responseObject];
        success(response);
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        failure(error);

    }];
}

and I have a

- (void)cancelCurrentRequest;

methods which all that does is

- (void)cancelCurrentRequest
{
    if(_currentRequest) {
        [_currentRequest cancel]; _currentRequest = nil;
    }
}

Now, I don't think this is good practice and when the method is called I get (NSURLErrorDomain error -999.) which is why I need some advice on getting this done correctly.

Thank you in advance.
