Hi, adding to an old thread, but is this implemented for Objective C Library?

 

When I try to use cancel(), the app crashes with:

 

Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'You must override cancel in a subclass'

 

Thanks!

Hi Jiho, yes, this is available in the Objective-C SDK, but that's a known issue in version 2.0.6 in particular. You can use 2.0.5 as a workaround for now.

      The override issue in 2.0.6 is fixed now in version 3.0.0.

      Do we need to explicitly cancel the upload requests, or is it enough to release the objects by setting it to nil? Example, I have

       dbUploadTask = client?.files.uploadSessionStart(input: data)
 dbUploadTask?.response(completionHandler: { [weak self] (result, error) in

}

      Then is it safe to set the object to nil while upload is in progress? Or is it necessary to call cancel() before setting it to nil?

      dbUploadTask = nil

        DS6 If you want to cancel the request, you should explicitly call `cancel`. (I can't guarantee that `nil`ing the object will be sufficient.)
