iPhone SDK: Setting the size of UISearchDisplayController's table view

The key to solving this one was finding out when to change the geometry of the table view. Calling:

[self.searchDisplayController.searchResultsTableView setFrame:someframe];

after creating the UISearchDisplayController was futile. The answer was this delegate method:

-(void)searchDisplayController:(UISearchDisplayController *)controller didShowSearchResultsTableView:(UITableView *)tableView {
    tableView.frame = someframe;
}

Note, I had also tried -searchDisplayController:didLoadSearchResultsTableView but it did no good in there. You have to wait until it's displayed to resize it.

Also note that if you simply assign tableView.frame = otherTableView.frame, the search results table overlaps its corresponding search bar, so it is impossible to clear or cancel the search!

My final code looked like this:

-(void)searchDisplayController:(UISearchDisplayController *)controller didShowSearchResultsTableView:(UITableView *)tableView {

    CGRect f = self.masterTableView.frame;  // The tableView the search replaces
    CGRect s = self.searchDisplayController.searchBar.frame;
    CGRect newFrame = CGRectMake(f.origin.x,
                                 f.origin.y + s.size.height,
                                 f.size.width,
                                 f.size.height - s.size.height);

    tableView.frame = newFrame;
}
