I think the documentation is (as so often) just wrong. In experimenting with this for my book, I found the UIViewController searchDisplayController property useless except in the special case where the whole thing is set up automatically in the nib. I ignore the searchDisplayController property and simply retain the UISearchDisplayController myself in a retain-policy property designed for that purpose. See the example here: <https://github.com/mattneub/Programming-iOS-4-Book-Examples/tree/master/p536p550searchableTable> And, for what I mean by "where the whole thing is set up automatically in the nib", here: <https://github.com/mattneub/Programming-iOS-4-Book-Examples/tree/master/p557p571automaticSearchPopover> (But, as my book says, I find that second arrangement very unpleasant, because you're not given access to the stuff you need access to, like the popover controller.) m. -- matt neuburg, phd = m...@tidbits.com, <http://www.apeth.net/matt/> A fool + a tool + an autorelease pool = cool!
