Question

I want to display results instantly while user enters some information (like google search). For now, I am doing this using a button. Is there a way to do it instantly? Thanks for any help.

Answer 1

Yes, if the search field is a UISearchBar in its delegate you can implement:

- (void)searchBar:(UISearchBar *)srcBar textDidChange:(NSString *)searchText {
[self performSelectorInBackground:@selector(backgroundAutocomplete:)
                           withObject:searchText];
}

and do something useful in the “backgroundAutocomplete” method, like populating a UITableView with suggestions.
The method will be called every time a user types a character…
