ios6 - How to get list of existing entities(tables) in core data -


How to get a list of existing entities (tables) for a particular schema (managed object model) The concept has begun implementing and is stuck with these points, please

something like: SELECT COUNT (*) from info_schema.tables WHERE table_schema = 'dbName';

Thanks

You should read. To obtain organizations for a specific NSManagedObjectModel , you will use one of the following (assuming that you have NSManagedObjectModel named objectModel Is):

  NSArray * myEntities = [objects model entities]; // The array of all entities in the model   

or

  NSDictionary * myEntities = [Object Model Entry Binam];   

You can read more in.

It seems that you are coming from a SQL background (like I was). Core data has many concepts that are different - sometimes to get better, once you understand them, sometimes you need more work than a simple SQL statement, I think SQL is important to access core data without "stuff" and behave in the same way as if you are using a database for the first time - it will help to avoid frustration.
