iOS iCloud Data Storage Guidelines

Oct 10, 2011 4:27 PM

If you have used the Digital Publishing Suite to create a multi-folio viewer for the iPad, you've probably gotten a message from Apple indicating that you should store data in a different location. With the v14 format and earlier, the Viewer Builder stored downloaded folios in the Documents folder, which is backed up in iTunes. With the v15 format and later, the Viewer Builder will store downloaded folios in the caches folder, and it will not be backed up in iTunes. This is true of both the current iOS4 and the new iOS5 soon to be released. With the iCloud feature in iOS5, storing folios in the Documents folder is undesirable.


To comply with Apple's guidelines, please rebuild your multi-folio viewer app using the v15 version, and submit your update app to Apple. Note that you do not need to update your folio tools. The v15 viewer is backwards compatible with all folios created with previous tools.


Once Apple approves your viewer app update and customers update the app on their devices, all folios they've downloaded are moved automatically from the Documents folder to the caches folder. These folios remain in the caches folder until customers archive their folios or update the iOS. If your customers update to iOS5 and then update your viewer app, they will not have to re-download any folios. If they update your viewer app and then install iOS5, they'll have to re-download their folios.

    Is there a running log of all updates, changes, etc. regarding DPS? If I am away from this forum for a few days, something like this could get lost.


    A running feed on would be great. More than just software updates. The above post for example, and the release of VB1.5.1.

    I agree, the announcement about the new Folio Producer tools has disappeared

    Have to agree,


    the new folio tools quietly disappeared any reasons why Adobe.

    "We're working on a way to make announcements and notifications..."
