细胞subviews消失，而滚动的uitableview

Question

我正在做下面的代码。问题是，当我在滚动一个单元将会无形部分，当我们再次来到可见部分细胞的子视图都走了样标签等

代码：

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { 

    static NSString *CellIdentifier = @"playcell"; 
    CustomCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; 
    if (cell == nil) { 
     [[NSBundle mainBundle] loadNibNamed:@"CustomCell" owner:self options:nil]; 
    } 
    if (indexPath.section == 0) { 
     if (indexPath.row == 0) { 
      [cell.backgroundCellBtn setBackgroundImage:[UIImage imageNamed:@"header.png"] forState:UIControlStateNormal]; 
      cell.backgroundCellBtn.userInteractionEnabled = NO; 
      cell.nameTextLbl.hidden = YES; 
      cell.playtimeLbl.hidden = YES; 
      cell.lineSperatorImageView.hidden = YES; 
     }else if (indexPath.row == self.yourTurnPlayList.count +1) { 
      [cell.backgroundCellBtn setBackgroundImage:[UIImage imageNamed:@"footer.png"] forState:UIControlStateNormal]; 
      cell.backgroundCellBtn.userInteractionEnabled = NO; 
      cell.nameTextLbl.hidden = YES; 
      cell.playtimeLbl.hidden = YES; 
      cell.lineSperatorImageView.hidden = YES; 

     } 
     else { 
      int pathValue = indexPath.row -1 ; 
      if (pathValue > (-1) && pathValue < self.yourTurnPlayList.count) { 
       [cell.backgroundCellBtn setBackgroundImage:[UIImage imageNamed:@"sample.png"] forState:UIControlStateNormal]; 
       [cell.backgroundCellBtn setBackgroundImage:[UIImage imageNamed:@"sample.png"] forState:UIControlStateHighlighted]; 
       [cell.backgroundCellBtn setBackgroundImage:[UIImage imageNamed:@"sample.png"] forState:UIControlStateSelected]; 

       GamePlay *gamePlay = [self.yourTurnPlayList objectAtIndex:pathValue]; 
       cell.backgroundCellBtn.tag = pathValue; 
       cell.nameTextLbl.text = [self getCurrentPlayerFormattedName:gamePlay]; 
       cell.playtimeLbl.text = [NSString stringWithFormat:@"played %@",[Helper getLastPlayedStringFromUnixTime:gamePlay.lastMoveTime]]; 
      } 
     } 
    } else if (indexPath.section == 1) { 
     if (indexPath.row == 0) { 
      [cell.backgroundCellBtn setBackgroundImage:[UIImage imageNamed:@"header2"] forState:UIControlStateNormal]; 
      cell.backgroundCellBtn.userInteractionEnabled = NO; 
      cell.nameTextLbl.hidden = YES; 
      cell.playtimeLbl.hidden = YES; 
      cell.lineSperatorImageView.hidden = YES; 
     }else if (indexPath.row == self.theirTurnPlayList.count +1) { 
      [cell.backgroundCellBtn setBackgroundImage:[UIImage imageNamed:@"footer2.png"] forState:UIControlStateNormal]; 
      cell.backgroundCellBtn.userInteractionEnabled = NO; 
      cell.nameTextLbl.hidden = YES; 
      cell.playtimeLbl.hidden = YES; 
      cell.lineSperatorImageView.hidden = YES; 

     } 
     else { 
      int pathValue = indexPath.row -1 ; 
      if (pathValue > (-1) && pathValue < self.theirTurnPlayList.count) { 
       [cell.backgroundCellBtn setBackgroundImage:[UIImage imageNamed:@"sample.png"] forState:UIControlStateNormal]; 
       [cell.backgroundCellBtn setBackgroundImage:[UIImage imageNamed:@"sample.png"] forState:UIControlStateHighlighted]; 
       [cell.backgroundCellBtn setBackgroundImage:[UIImage imageNamed:@"sample.png"] forState:UIControlStateSelected]; 
       cell.backgroundCellBtn.userInteractionEnabled = NO; 
       GamePlay *gamePlay = [self.theirTurnPlayList objectAtIndex:pathValue]; 
       cell.nameTextLbl.text = [self getCurrentPlayerFormattedName:gamePlay]; 
       cell.playtimeLbl.text = [NSString stringWithFormat:@"%@",[Helper getLastPlayedStringFromUnixTime:gamePlay.lastMoveTime]]; 
      } 
     } 
    } 

    return cell; 
}

由于电池是由你隐藏。当他们重新使用，他们是隐藏的，所以你sholud设置隐藏是NO，重复使用
