How to find out when the text in the search bar changes

I have a search bar and I need to be notified when the bar text changes, how can I do this? I need to reload the table view every time the string value of the search string changes

Create an IBOutlet for your search, then add the searchBar properties to your delegate.

This method should be called when the text in the search bar changes:

- (void)searchBar:(UISearchBar *)searchBar textDidChange:(NSString *)searchText;

Of course, you should add protocols for your viewController monitor:

    <UISearchBarDelegate, UISearchDisplayDelegate>
