      UIButton *btnUncheck=[[UIButton alloc] initWithFrame:CGRectMake(260, 35, 20, 20)];

    //btnUncheck=[UIButton buttonWithType:UIButtonTypeCustom];
     btnUncheck.tag=indexPath.row;
 [btnUncheck setImage:[UIImage imageNamed:@"NO.png"] forState:UIControlStateNormal];

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-

是的你可以。在checkBoxClicked:中,将已检查项的行保存在实例变量中。然后,重新加载该行,以便再次调用cellForRowAtIndexPath。就像是-

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-

然后,在cellForRowAtIndexPath:中,检查self.checkedRow并添加标签。就像是-

if(indexPath.row == self.checkedRow)
{
       UILabel* label = [[UILabel alloc] init];
       //label.text = [NSDate date]; //use date formatters here
       [cell.contentView addSubview:label];
}
