Autocomplete word as you are typing

I am trying to figure out how I would go about doing an autocompletion 
of a word as you are typing.  I am trying to do something like any 
autocomplete done on the web where you start typing in your 
information and if there is a 1 to 1 match against a list it suggests 
a completion to the word.  I know there is the 
"textView:completions:forPartialWordRange:indexOfSelectedItem:" 
delegate method, but I want something that will happen as the person 
types without hitting the escape key.


Does anyone have any examples, advice, delegate methods to look at.

Thanks in advance
