I used a combination of @boliva's answer and also @radiospiel's answer to a different SO question:

@interface SearchViewController : UIViewController  {
    // all of our ivar declarations go here...
    BOOL shouldBeginEditing;
    ....
}

...
@end

@implementation SearchViewController
...
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {
    if ((self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil])) {
        ...
        shouldBeginEditing = YES;
    }
}
...

- (void) searchBar:(UISearchBar *)theSearchBar textDidChange:(NSString *)searchText {
    // TODO - dynamically update the search results here, if we choose to do that.

    if (![searchBar isFirstResponder]) {
        // The user clicked the [X] button while the keyboard was hidden
        shouldBeginEditing = NO;
    }
    else if ([searchText length] == 0) {
        // The user clicked the [X] button or otherwise cleared the text.
        [theSearchBar performSelector: @selector(resignFirstResponder)
                        withObject: nil
                        afterDelay: 0.1];
    }
}

- (BOOL)searchBarShouldBeginEditing:(UISearchBar *)bar {
    // reset the shouldBeginEditing BOOL ivar to YES, but first take its value and use it to return it from the method call
    BOOL boolToReturn = shouldBeginEditing;
    shouldBeginEditing = YES;
    return boolToReturn;
}
@end
