问题 I had the previous question here about database location. What different between store database in different locations in iOS? I'm confused in copying pre-seeded database to the writable location. Now, every time I run and build my app, the in-use database will be replaced by pre-seeded db. And in the future, if I update my app version, how do I prevent the database from being replaced? 回答1: how do I prevent the database from being replaced?

问题 I have 1 table with multiple columns. On the app, we are looking forward to add 4 dynamic filters like (cat, size, color,shape).
