Yes, you can. In checkBoxClicked:, save the row of the checked item in an instance variable. Then, reload the row so that cellForRowAtIndexPath is called again. Something like-
self.checkedRow = sender.tag;
[self.tableView reloadRowsAtIndexPaths:[NSArray arrayWithObject:[NSIndexPath indexPathWithIndex:sender.tag]] withRowAnimation:UITableViewRowAnimationNone];
Then, in cellForRowAtIndexPath:, check for self.checkedRow and add a label. Something like-
if(indexPath.row == self.checkedRow)
{
UILabel* label = [[UILabel alloc] init];
//label.text = [NSDate date]; //use date formatters here
[cell.contentView addSubview:label];
}
