        static NSString *myCellIdentifier = @"LifeShopsList";
        LifeShopsList *cell = (LifeShopsList *)[tableView dequeueReusableCellWithIdentifier:myCellIdentifier];
        
        if (cell == nil) {

                    }
                    else
                    {

                    }
                    cell.address.text=news.address;
                    cell.times.text=news.time;
                    switch ([news.level integerValue]) {
                        case 1:

                            break;

                            break;
                        default:
                            break;
                    }
                    
                    cell.contentView.backgroundColor = [UIColor clearColor];
                    UIView *aView = [[UIView alloc] initWithFrame: cell.contentView.frame];
                    UIColor *cellColor = nil;
                    if ([[NSUserDefaults standardUserDefaults] boolForKey:@"nightMode"]){
                        
                        cell.title.textColor = [UIColor colorWithRed:164.0/255 green:165.0/255  blue:169.0/255 alpha:1.0f];

                    }else{

                    }
                    
                    aView.backgroundColor = cellColor;
                    cell.selectedBackgroundView = aView;  // 设置选中后cell的背景颜色
                    break;
                }
            }
            
            
        }
        return cell;这是我的一段代码，注意看红色部分

Answer 2

self.commentsCell = [[[NSBundle mainBundle] loadNibNamed:@"HomeNewsTableCell" owner:self options:nil] lastObject];
也可以这么写

Answer 3

您的代码好复杂呵，阅读后我的理解是，您的代码意思是如果是第0行，则隐藏那些控件，其他行则显示，这些都是在一个xib内进行的。您的xib只有一个，我有二个xib哦。如何根据不同行加载不同的xib，能否给出更明确的提示？

Answer 4

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    if (indexPath.row==1) { //第一行
              static NSString *simpleTableIdentifier = @"SimpleTableCell";
                SimpleTableCell *cell = (SimpleTableCell *)[tableView               dequeueReusableCellWithIdentifier:simpleTableIdentifier];
            
        if(cell == nil) {
                 cell= [[[NSBundle mainBundle] loadNibNamed:@"SimpleTabelCell" owner:self options:nil] lastObject];;
         }
         cell.imageview_1 = [UIImage imageNamed:@"1.png"];
         cell.imageview_2 = [UIImage mageNamed:@"2.png"];
         return cell;
      }
   
    if (indexPath.row==2) {  //第二行
           static NSString *simpleTableIdentifier = @"SimpleTableCell2";
           SimpleTableCell2 *cell = (SimpleTableCell2 *)[tableView                       dequeueReusableCellWithIdentifier:simpleTableIdentifier];
             
       if(cell == nil) {              cell= [[[NSBundle mainBundle] loadNibNamed:@"SimpleTableCell2" owner:self options:nil] lastObject];;
           }
        cell.imageview_1.image = [UIImage imageNamed:@"3.png"];
        cell.imageview_2.image = [UIImage imageNamed:@"4.png"];
        cell.imageview_3.image = [UIImage imageNamed:@"5.png"];
        return cell;
    }
    return nil;
}

Answer 5

indexPath.row==0 是第一行。indexPath.row==1 是第二行  。

Answer 6

修改为indexPath.row=0和indexPath.row==1，程序没有崩溃，但显示的二行中，每行都只有二个图片。还是达不到第一行放二个图片，第二行放三个图片的效果。
