AFNetworking 2.0 cancel specific task

Question

I am trying out afnetworking 2.0 and just trying to figure out how to cancel specific tasks. The old way would be to use something like

[self cancelAllHTTPOperat         


        

Answer 1

You can store the task in a variable so you can access it later:

NSURLSessionDataTask* task = [self GET:path parameters:nil success:^(NSURLSessionDataTask *task, id responseObject) {
            completionBlock(responseObject);
        } failure:^(NSURLSessionDataTask *task, NSError *error) {
            errorBlock(error);
        }];

Then simply cancel it with [task cancel].

Another way would be to save the task ID of the task and later ask the URL session for its tasks and identify the task you wish to cancel:

// save task ID
_savedTaskID = task.taskIdentifier;

// cancel specific task
for (NSURLSessionDataTask* task in [self dataTasks]) {
    if (task.taskIdentifier == _savedTaskID) {
        [task cancel];
    }
}
