Searching in iOS apps

I want to store about 10000 strings in my iOS app. I want the ability to quickly search these strings (similar to searching on the devices themselves when you swipe to the left of the home screen). Searching should include a form of "suggest" or auto-comp开发者_JAVA技巧lete. For example typing "food" into the search box should bring up a list containing "food stores" "food recipes" etc.

How can I implement this type of search? Perhaps a sqlLite database and ... ?

Cheers!

Have a look at Core Data

Depends on a case you can follow two ways:

1. Integrate Core Data as Diederik Hoogenboom suggested.

2. Use filteredArrayUsingPredicate method of NSArray and build a predicate for your needs as described in following document Predicate Programming Guide

   I am personally prefer option #2, it is easier to start and depends on solution's performance and memory footprint you can always switch to more complex #1 option.
