Best way to implement a custom UITableViewCellAccessoryType to use as check mark (like a to-do list).

Question

I need to create a checklist using a UITableView with the accessoryView as a custom check box and tick, what would be the best (fast & efficient) way to do this?

Also what would be the best way to tick/untick it from within accessoryButtonTappedForRowWithIndexPath and store/retrieve the current state of the row (checked/unchecked) for example:

-(void)tableView:(UITableView *)tableView accessoryButtonTappedForRowWithIndexPath:(NSIndexPath *)indexPath {
   if (something==isChecked) {
       change accessoryView to unchecked
       // do stuff
   } else {
       change accessoryView to unchecked
       // do stuff
   }
}

Thanks!

I'm not sure how close this is to what you want but it's an example of a to do list that I used to learn about SQLite. http://icodeblog.com/2008/08/19/iphone-programming-tutorial-creating-a-todo-list-using-sqlite-part-1/

I have just found Apple has created an example of exactly this! Here is a link for anybody looking for the same thing:
