V2 Obj-C equivalent to [DBFilesystem sharedFilesystem].status.anyInProgress

Is there a V2 Obj-C equivalent to the Sync API [DBFilesystem sharedFilesystem].status.anyInProgress ?

That is, how can I test if there are uploads in progress after fileRoutes batchUploadFiles is called but before the responseBlock is run?

Hi Steve, no, unfortunately the SDK doesn't offer anything analogous to status.anyInProgress, but I'll be sure to pass this along as a feature request. You'll need to keep track of this state via your app's logic instead. (I.e., set some state when kicking off the operation, and unset it when the response block runs.)

Thanks Greg.

The specific situation I'm trying to accommodate is where a user repeatedly changes a file (e.g. editing an online document or cropping a photo). Is it sufficient to just call fileRoutes batchUploadFiles repeatedly and the document at Dropbox reflects the last invocation? Or do I need to add logic to queue repeated updates to the same document?

The exact behavior in that case would depend on which of the calls succeed first, and what write mode you're using, so it would be safer to queue these up in order.

The asynchronous and non-deterministic nature of the API will make that (ahem) "interesting".

One final question: do you know of any situation (apart from the app terminating) where the responseBlock in a fileRoutes batchUploadFiles API call will fail to run?

There are some complications around background sessions. You can find more information about that here:

Steve, an `uploadsInProgress` method has been added to the batch upload logic in the latest version of the SDK. Let us know if you have any problems with it.

Thanks Stephen. I plan to use it to detect if a background batch upload session has abnormally terminated for any reason (unlikely, but it can happen). If that occurs I can re-initiate the batch upload.
