UITableView cell上的button和label问题

 int  isGet = [[dic objectForKey:@"IsGet"] intValue];

    if (isGet == 0)

    {

        [cell.takeTaskButton setTitle:@"已完成" forState:UIControlStateNormal];

         cell.completeLabel.text = @"";

        [cell.takeTaskButton setBackgroundImage:nil forState:UIControlStateNormal];

        cell.takeTaskButton.titleLabel.font = [UIFont fontWithName:@"Heiti SC" size:15];

        [cell.takeTaskButton removeTarget:self action:@selector(buttonWithGetTask:) forControlEvents:UIControlEventTouchUpInside];

        [cell.takeTaskButton setTitleColor:[UIColor colorWithRed:49.0/255 green:48.0/255 blue:48.0/255 alpha:1.0] forState:UIControlStateNormal];

        cell.takeTaskButton.userInteractionEnabled = NO;

   }

    else if (isGet == 1)

    {

        cell.completeLabel.text = [NSString stringWithFormat:@"%i",times];

        [cell.takeTaskButton setBackgroundImage:Nil forState:UIControlStateNormal];

        [cell.takeTaskButton setTitle:[NSString stringWithFormat:@"进行中  \r\r /%i",Conditions] forState:UIControlStateNormal];

        cell.takeTaskButton.titleLabel.numberOfLines=3;

        cell.takeTaskButton.titleLabel.textAlignment = NSTextAlignmentCenter;

        cell.takeTaskButton.titleLabel.font = [UIFont fontWithName:@"Heiti SC" size:12];

        cell.takeTaskButton.titleLabel.textColor  = [UIColor colorWithRed:28.0/255 green:86.0/255 blue:135.0/255 alpha:1.0];

        cell.takeTaskButton.userInteractionEnabled = NO;

        [cell.takeTaskButton removeTarget:self action:@selector(buttonWithGetTask:) forControlEvents:UIControlEventTouchUpInside];

    }

    else if (isGet == 2)

    {

        cell.takeTaskButton.userInteractionEnabled = YES;

        cell.completeLabel.text = @"";

        cell.backgroundColor = [UIColor clearColor];

        [cell.takeTaskButton setSpriteButtonWithHDFile2:@"hall_task_take_btn" HDFloat:P_DISPLAY];

        [cell.takeTaskButton setTitle:@"" forState:UIControlStateNormal];

        [cell.takeTaskButton addTarget:self action:@selector(buttonWithGetTask:) forControlEvents:UIControlEventTouchUpInside];

        cell.takeTaskButton.tag = indexPath.row;

    }

在每次赋值之前，要先清空之前赋的值，才能不会重用，不然会有重用问题的出现
