Subject [jira] [Commented] (CB-1561) Using Storage API - rejected by Apple
Date Thu, 18 Oct 2012 19:56:03 GMT

    [ https://issues.apache.org/jira/browse/CB-1561?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13479305#comment-13479305

Michal Mocny commented on CB-1561:
----------------------------------

Samuel,
Localstorage was never directly backed up to iCloud before ios6, and while we did accidentally
backup a COPY of localstorage (was only intended to be a local backup), apps are now apparently
starting to get rejected by apple app review for doing this, so that needs to be disabled.

No one wants to break Localstorage, and we are re-evaluating whether to enable icloud backup
on ios6 for other reasons, but if you want to have user data backed up to iCloud, we suggest
using the FileSystem API.  Localstorage is not considered data generated by the user.

> our App uses the Sotrage-API to store data which is being loaded upon first launch. 
> The app is rejected given the following reasoning:
> 'Your app does not follow the iOS Data Storage Guidelines, as required by the App Store
Review Guidelines.
> Please be sure to set the "Do not back up" attribute for all data which is not generated
or modified by the user. To check how much data your app is storing:
> - Install and launch your app
> - Go to Settings > iCloud > Storage and Backup > Manage Storage
> - If necessary, select "Show all apps"
> - Check your app's storage
> The iOS Data Storage Guidelines indicate that only content that the user creates using
your app, (documents, new files, edits, etc.) may be stored in the /Documents directory -
and backed up to iCloud.
> Temporary files used by your app should only be stored in the /tmp directory. Please
remember to delete the files stored in this location when the user exits the app.
> Data that can be recreated but must persist for proper functioning of your app or because
customers expect it to be available for offline use should be appended with the "do not back
up" attribute. For NSURL objects, add the NSURLIsExcludedFromBackupKey attribute to prevent
the corresponding file from being backed up. For CFURLRef objects, use the corresponding kCFURLIsExcludedFromBackupKey
attribute.
> For more information, please see Technical Q&A 1719: How do I prevent files from
being backed up to iCloud and iTunes?.
> Please revise your app so that it adheres to the iOS Data Storage Guidelines.'
> Is there a possibility to set this flag for the WebSQL Database file(s)?
> At least for us this is a blocker ...
