Concurrent task in AFNetworking

Currently I am running 3 task concurrently using AFNetworking.But my problem is that I need to refresh tableview once all the above three task complete.But as in AFNetworking all the operation are async. So any operation can finish first. I am not getting a point where I need to refresh my tableview. I am planning to do some critical section type implementation.Is there can other way to accomplish the above.

Use the built-in batched request operation feature of AFNetworking. The completion handler for the batch would include the logic to refresh your data source once all of the operations have finished.

Maybe having some sort of 'active requests array' is a solution for you.

  • Every time you make a request, add it to the (mutable) array.
  • When the request finishes, remove it from the array.
  • Every time a request finishes, check the array length (count).
  • If your array has become empty again, all request have been finished and you can reload your tableview.
