Really got stuck on this little code challenge. Here is my answer which is obviously wrong. Why oh Why don't they post an answer…?

I would really appreciate any help.

// This code is excerpted from the didSelectRowAtIndexPath method of a view controller

UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];

// Add your code below to mark rows as selected or not! if (cell.accessoryType == UITableViewCellAccessoryNone) { cell.accessoryType = UITableViewCellAccessorynone;

you have the right idea

this code is run when the user taps a cell. first you check to see if the cell doesnt have a checkmark. if it doesnt, add a checkmark. else (it already has a check) remove the check mark.

// This code is excerpted from the didSelectRowAtIndexPath method of a view controller

UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];

// Add your code below to mark rows as selected or not!

//check and see if it DOESNT have a checkmark when its tapped
if (cell.accessoryType == UITableViewCellAccessoryNone) {
        //not checked yet, so we need to add a check to the cell
        cell.accessoryType = UITableViewCellAccessoryCheckmark;
}
else {
       //already checked, remove the checkmark
       cell.accessoryType = UITableViewCellAccessoryNone;
}
