UISearchDisplayController

Question

I do not find anything good in the textbook or anything in the search bar.

I do not understand how this works.

Can you help me or give me a good link or sample code (I see Apple's TableSearch sample code, and this is ultimately bad.)

Update:

I forgot to say that I am working with a SQLite database.

I saw a lot of good lessons in the search bar, but the problem is in my database. Well, I need to mix the predicate and searchBar.
