AFNetworking 2: How to cancel a AFHTTPRequestOperationManager request?

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.
