iOS Tutorial on Polling Start

[mazzuna]

In the iOS Tutorial it says:

---

Enable Automatic Synchronization After Changes are Detected:

You’ll need to turn on remote change polling immediately after the document sync manager has finished registering, so add the following into the relevant delegate method:

• (void)documentSyncManagerDidFinishRegistering:(TICDSDocumentSyncManager *)aSyncManager { ... [aSyncManager beginPollingRemoteStorageForChanges]; }

---

If the whole stores need to be downloaded this causes the sync changes to be downloaded and "applied" before the whole store is downloaded - causing some of those changes not be applied. I was mainly seeing the problem for deletions. It could also be due to how I have application structured. My own documentSyncManagerDidFinishRegistering: method is as follows:

(this is after I changed it so that it works correctly for me)

• (void)documentSyncManagerDidFinishRegistering:(TICDSDocumentSyncManager *)aSyncManager {

  if (self.shouldDownloadStoreAfterRegistering) { [aSyncManager initiateDownloadOfWholeStore]; } else { [aSyncManager initiateSynchronization];

  [self.documentSyncManager beginPollingRemoteStorageForChanges];

  }

  self.documentSyncManagerReady = YES;

  NSUserDefaults * ud = [NSUserDefaults standardUserDefaults]; [ud setBool:YES forKey:OPTIONS_SYNC_WITH_DROPBOX_ON];

}

If a download of the whole stores is necessary I put [self.documentSyncManager beginPollingRemoteStorageForChanges] in documentSyncManagerDidFinishDownloadingWholeStore:.

That's a good catch Mazen, thanks.
