iPhone App Rejection due to "iOS data storage Guidelines". Need help.

[rambo]

My iphone app has got rejected recently & with below mentioned reason :



"We found that your app does not follow the iOS Data Storage Guidelines, which is not in compliance with the App Store Review Guidelines."



For this app I was storing database (sqlite file) in /Documents/ directory for iOS 5.0.1 & above & for iOS 5.0 & below versions I used Library/Cache directory.

For other data like PDF & artwork images which I was downloading from server I followed the same approach as above like: iOS 5.0.1 & Later: Saved these data into /Documents/ directory iOS 5.0 & earlier versions: Saved data to Library/Cache directory.



Is the above approach correct?



As per Apple guideline: 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 /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.



Also very confused about that "do not back up" attribute assignment for the data stored for iOS 5.0.1 & later. For which files i need to assign this flag ? Can i use it for database?.

Need to get rid of these rejection as it has happened twice. Please provide some guidance for storing the data for my app.



I am using a 1) sqlite DB file, 2) pdf files,3) csv file & 4) images in my app where csv,pdf & images are dynamic content.



Thanks in advance. Looking forward for the firm solution.

Well, if you read what the guidelines states, you will understand your problem. Apple does not want unnecessary resources being backed up to iCloud.
You must mark your files with the No-backup extended attribute, its easier if you put everything in a folder and mark your folder with the attribute.
