ios - coredata sqlite location, Library/Application Support and iCloud -

we got rejected during review process following issues:

==========

2.23

we still found app not follow ios data storage guidelines, required per app store review guidelines.

in particular, found on launch and/or content download, app stores non user-generated content in icloud backup directories, not appropriate. check how data app storing:

• install , launch app
• go settings > icloud > storage & backup > manage storage
• if necessary, tap "show apps"
• check app's storage

the ios data storage guidelines indicate content user creates using app, e.g., documents, new files, edits, etc., should backed icloud.

temporary files used app should stored in /tmp directory; please remember delete files stored in location when user exits app.

data can recreated must persist proper functioning of app - or because customers expect available offline use - should marked "do not up" attribute. nsurl objects, add nsurlisexcludedfrombackupkey attribute prevent corresponding file being backed up. cfurlref objects, use corresponding kcfurlisexcludedfrombackupkey attribute.

==========

our (ios 6 only) app holds user's collection of favourite cars.

we prepopulate collection collection of classic cars can delete, or edit please within app. entire databse of cars, including user creates , preloaded entries, should backed icloud.

currently, each car, whether created user or 1 of starting collection, stored within /library/application support/com.company.appname/datamodel.sqlite understand backed icloud. car entries have image file saved in same directory sqlite database file.

the cars presented in tableview using fetchedresultscontroller , standard core data code.

having read through these, still unclear how conform guidelines if have database needs backed must start preloaded, user modifiable/deletable items?

use separate persistent store seed data. backup seed cars have been modified user.

this easy do. @ recent apple examples wwdc 2013. scenario reason apple invented nspersistentstorecoordinator.

you introduce attribute indicates if entry "seed" or not (you set false once edited , copy on other store).
