UISearchBar searches history

I'd like to show use开发者_运维技巧r history of his previous searches in UISearchBar so he can choose from the list instead of retyping.

Is there any built-in control in xcode for this, or i have to implement it myself?

There's no built-in control that does what you want. Searchbar doesn't even know what was previous search terms. You have to save it somewhere (Array or dictionary) for all or last 10 search terms and display in whichever you want.
