Yes, this is exactly what I'm wondering too. Without it, we can't build any apps that download content without the risk of the content being deleted.

Here's the background before Apple introduced the new "do not back up" attribute:

Fortunately, Apple addressed it after that blog post in 5.0.1. See bullet #4 here, quoted below

https://developer.apple.com/icloud/documentation/data-storage/

Q:  My app has a number of files that need to be stored on the device permanently for my app to function properly offline. However, those files do not contain user data and don't need to be backed up. How should I store those files in iOS 5?

 

A: Starting in iOS 5.0.1 a new "do not back up" file attribute has been introduced allowing developers to clearly specify which files should be backed up, which files are local caches only and subject to purge, and which files should not be backed up but should also not be purged. In addition, setting this attribute on a folder will prevent the folder and all of its contents from being backed up.

 

Important: The new "do not back up" attribute will only be used by iOS 5.0.1 or later. On iOS 5.0 and earlier, applications will need to store their data in <Application_Home>/Library/Caches to avoid having it backed up. Since this attribute is ignored on older systems, you will need to insure your app complies with the iOS Data Storage Guidelines on all versions of iOS that your application supports.

Now we just need Adobe to support the attribute in the AIR SDK. What do you say Adobe?

You might want to check out our ANE (Adobe Native Extension) solution that enables your FB projects to abide by the Apple's Data Storage guidelines.

Hi all,

Any current info as to the status of this issue? I did find the jampot solution, but that appears to be for Flash Builder only and it'd be nice to have a simpler solution.

Will AIR 3.2 address this issue?

Would be nice if Adobe integrated a method to flag document directory/user accessible files, as per Apple's requirements, that should not be backed up to iCloud.

Thanks.

Thanks for the info, sinious.

Where you'll spend most of your time perhaps is getting adt to compile a proper ipa. It wasn't worth my time, Flash Builder solved the issue completely (albeit with some project tweaking, and I had no idea what flex was prior).

 

 

There's the problem. It doesn't work (effectively) for those of us with Flash CS 5.5.

Need a solution, Adobe.

Thanks!

I don't understand.

This doesn't sound like it "works fine" to me.

I'm a new app developer (though previous experience with AS), a one-man team. So the $700 Flash Builder as a solution is simply not an option.

I understand Adobe wishes to provide cross-platform support, but how soon they respond to compatibility issues like this with iOS will directly influence how long I remain an Flash/AIR developer versus looking towards learning a different language (already making sure all my code is object-oriented to prepare for a possible transition). Apple's app store is where the money's at and I don't see this changing anytime in the near future.

Thanks for the links. I'll give 'em a try. Hopefully Flash Pro 6 is coming soon and will be updated for ANE, or better yet, address the iOS storage directory issue directly!

Can I get instructions for how to use this with Mac Flash Pro? Do I need both Mobile Backup and Data Storage to be listed as extensions in the app xml file? Also how do I use the Data Storage and Mobile Backup classes? Any help is appreciated. I just finished a big app that requires offline access of files and this is holding me back from publishing.
