I have used core data in my apps. My application works fine in online and offline mode . I have doubt about, how to write a query in Core data(Similar SQLite). I wrote a query and used in SQLite. But I want to know about, how to write a query(select, insert, update, etc,.) using core data.
Please guide me and give me some useful links.
You should read though Apple’s tutorial on Core Data. It goes through the process of making a very simple app that used Core Data. For more complicated queries you will want to make a predicate to restrict the returned values.
