iphone - Why my application installed from cydia can't access core data? -

I wrote an application that uses coredata via cqrite works fine on simulator or on device Installing from Xcode I need to provide a trial version of the application for some others, such as UI Designer or QA, I decided to use Cydia for this work. Although it installs properly, it can not initially initialize the Store Coordinator: addPersistentStoreWithType reports zero and error objects COCO error 258 (It seems that NSFileReadInvalidFileNameError, am I right?). What's wrong with installing Cydia? Is anyone facing such a problem? Is there any other way to distribute an application between groups of people (not everyone in the appstore)? I think ad-hoc is not my case because they all live in different places.

You want to distribute your application: AdHoc method
