I have the indexPath of type NSIndexPath*,a reference to the tableView, I want to use 开发者_运维技巧these to get a handle on the corresponding cell.How dp I do this?

UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];

But note that that method returns nil if corresponding row is not visible at the moment (or indexPath is out of the table's range)
