Swift - Detect text enter on UISearchBar

Question

How do I detect when a user types into a UISearchBar? Should be really easy. Cannot find any help in the Class Reference. Is not this supposed to print?

func searchBarShouldBeginEditing(searchBar: UISearchBar) -> Bool{
    println("Started Editin'...")
    return true
}

Did you look at the docs for `UISearchBarDelegate`? – rmaddy Feb 13 '15 at 18:53 — rmaddy, Feb 13 '15 at 18:53

That would be because it is the responsibility of the UISearchBarDelegate to inform you of the text changing in a UISearchBar.

You have a good question, I struggled with a similar one in the past. @thatidiotguy is correct, you're going to need to implement the UISearchBarDelegate in order to be notified.

I believe the method that you're looking for is: filterContentForSearchText. It's a UISearchBarDelegate method that will send all the text in the box to this method each time you type or delete a character.

Can you suggest how the method works? With Code example, if possible. – tika Feb 13 '15 at 19:10
The code examples can be rather in-depth, can I refer you to this tutorial? It will help you get the full idea, in context: http://www.appcoda.com/search-bar-tutorial-ios7/ Please let me know if you have any other questions. – kbpontius Feb 13 '15 at 19:13
