Changing a custom accessoryView in a uitableviewcell?

I'm trying to change the custom accessoryView of a uitableviewcell immediately after the user clicks on the cell. How would I do this?

For the record, I'm using Matt Gallagher' custom table view tutorial:

http://cocoawithlove.com/2009/04/easy-custom-uitableview-drawing.html

Download link for source: http://projectswithlove.com/projects/EasyCustomTable.zip

EDIT

Tried this code, but it just changes the accessory AFTER touch-up. Also tried willSelectRowAtIndexPath with same result.

- (NSIndexPath *)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    UIImage *indicatorImage = [UIImage imageNamed:@"indicatorSelected.png"];
    UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:indexPath];
    cell.accessoryView = [[[UIImageView alloc] initWithImage:indicatorImage] autorelease];
    return indexPath;
 }

EDIT

Problem solved by making the background image of the cell contain the accessories. so the accessory was 'faked' by making it part of the image

Use the highlightedImage property of UIImageView:

UIImageView* arrowView = [[UIImageView alloc] initWithImage:normalImage];
arrowView.highlightedImage = selectedImage;
cell.accessoryView = arrowView;
[arrowView release];

Perhaps you can try to reload the cell in willSelectRowAtIndexPath/didSelectRowAtIndexPath:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    UIImage *indicatorImage = [UIImage imageNamed:@"indicatorSelected.png"];
    UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:indexPath];
    cell.accessoryView = [[[UIImageView alloc] initWithImage:indicatorImage] autorelease];
    [tableView reloadRowsAtIndexPaths:[NSArray arrayWithObjects:indexPath,nil] withRowAnimation:NO];
 }

Another recommendation: didSelectRowAtIndexPath returns void not NSIndexPath.

You could change the accessoryView in the selection method as shown:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
    cell.accessoryView = newView;
}

This just grabs the current cell that was selected and then changes the accessory view of it. Your view object would go where newView is.
