API v2 - Longpoll Objective C

[Raheel S.]

Hello,

I want a good example of a using ListFolderLongpoll, I am getting cursor errors and find little documentation as to how to receive changes notification.

I am using ObjC SDK V2.

Hi Raheel, you can find the documentation for listFolderLongpoll itself here.

Using it would look like this:

// cursor should be the Files.ListFolderResult.cursor as retrieved by the last call to listFolderContinue
DropboxClientsManager.authorizedClient?.files.listFolderLongpoll(cursor: cursor).response(completionHandler: { (result, error) in
    if ((result) != nil) {
        if (result?.changes)! {
            // There are changes, so call listFolderContinue to retrieve them
        } else {
            // listFolderLongpoll didn't report changes, so call listFolderLongpoll again
        }
    } else if ((error) != nil) {
        // Perform whatever error handling you want here
    }
})

Thanks Greg, I just figured that out. 

The new SDK is getting some used to.
