【英文标题】：allignment of images in table view cell is not proper

【问题描述】：

我已经创建了带有图像的表格视图，但图像不在正确的行中。我希望所有图像都在同一行 帮助我在模拟器中显示所有图像，因为我有超过 7 个案例处于切换状态。

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

    static NSString *simpleTableIdentifier = @"SimpleTableCell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];



    if (cell == nil) 
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:simpleTableIdentifier];
    
  UIImageView *imageView=[cell.contentView viewWithTag:1];
    switch (indexPath.row) 
        case 0:
            cell.textLabel.text = @"wake up";
            cell.detailTextLabel.text = @"wake up at 6 am and get ready for office";
            cell.imageView.image=[UIImage imageNamed:@"wake-up-early-200.jpg"];
           break;
           case 1:
            cell.textLabel.text = @"remainders";
            cell.detailTextLabel.text = @"today is ajay's bday wish him ";
            cell.imageView.image=[UIImage imageNamed:@"remainders.jpg"];
            break;
        case 2:
            cell.textLabel.text = @"shopping";
            cell.detailTextLabel.text = @"buy vegetables,fruits,dresses";
            cell.imageView.image=[UIImage imageNamed:@"shopping.jpg"];
            break;
        case 3:
            cell.textLabel.text=@"meeting";
            cell.detailTextLabel.text=@"meeeting at lanuch pad by 4pm";
            cell.imageView.image=[UIImage imageNamed:@"meeting.jpg"];
            break;
          case 4:
            cell.textLabel.text=@"airport";
            cell.detailTextLabel.text=@"bala is coming receive him on time";
            cell.imageView.image=[UIImage imageNamed:@"airport.jpg"];
            break;
        case 5:
            cell.textLabel.text=@"games";
            cell.detailTextLabel.text=@"time for refresh";
            cell.imageView.image=[UIImage imageNamed:@"games.jpg"];
            break;
        case 6:
            cell.textLabel.text=@"lunch";
            cell.detailTextLabel.text=@"go to lunch by 1pm";
            cell.imageView.image=[UIImage imageNamed:@"lunch.jpg"];
            break;
        case 7:
            cell.textLabel.text=@"coffee";
            cell.detailTextLabel.text=@"go to ccd at 3pm";
            cell.imageView.image=[UIImage imageNamed:@"coffee.jpg"];
        case 8:
            cell.textLabel.text=@"super market";
            cell.detailTextLabel.text=@"buy household items";
            cell.imageView.image=[UIImage imageNamed:@"market.jpg"];
            break;
        case 12:
            cell.textLabel.text=@"iPhone app";
            cell.detailTextLabel.text=@"iPhone app development training";
            cell.imageView.image=[UIImage imageNamed:@"iphone.jpg"];
            break;
    case 11:
            cell.textLabel.text=@"home";
            cell.detailTextLabel.text=@"going to home by 11pm";
            cell.imageView.image=[UIImage imageNamed:@"home.jpg"];
            break;

        default:
            break;
    




    //cell.textLabel.text = [todoitems objectAtIndex:indexPath.row];
    //cell.detailTextLabel.text = @"This Is A Very Very Long String";

        return cell;

【问题讨论】：

请正确格式化您的问题（使用 control+K 修复缩进问题，目前这很难阅读）

图片大小一样吗？没有透明框？

我明白了..我有很多案例，但只有 5 个案例被拿走并显示在模拟器中..为什么会这样？？

请更好地解释您的需求，以便我可以帮助您

能否添加输出图片以便我们理解？

【参考方案1】：

todoitems=[NSMutableArray arrayWithObjects: @"1.wake up",@"2.remainders",@"3.shopping",@"4.meeting",@"5.airport",@"6.home",nil];

应该改为：

todoitems=[NSMutableArray arrayWithObjects: @"1.wake up",@"2.remainders",@"3.shopping",@"4.meeting",@"5.airport",@"6.home",@"games",@"lunch",@"coffee",@"super market",@"iPhone app",@"home",nil];

我必须包括我在开关盒中使用过的所有项目.. 那是我犯的错误

它的数量是 6，你的案例是 12。修复你的数组

【参考方案2】：

你的 cell.imageView 是 UITableViewCell 的默认大小。我建议你去界面生成器并在 UITableViewCell 中拖动一个 UIImageView 并定义它的大小并将 UIImageView 标记值设置为 1。

Here in cell for Index path delegate access UIImageView this way

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

    static NSString *simpleTableIdentifier = @"SimpleTableCell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];


    if (cell == nil) 
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:simpleTableIdentifier];
    
UIImageView *imageView=[cell.contentView viewWithTag:1];

    switch (indexPath.row) 
        case 0:
            cell.textLabel.text = @"wake up";
            cell.detailTextLabel.text = @"wake up at 6 am and get ready for office";

        imageView.image=[UIImage imageNamed:@"wake-up-early-200.jpg"];
           break;
           case 1:
            cell.textLabel.text = @"remainders";
            cell.detailTextLabel.text = @"today is ajay's bday wish him ";

        imageView.image=[UIImage imageNamed:@"remainder.jpg"];
            break;
    default:
        break;

我已返回待办事项计数

确保 - (NSInteger)numberOfRowsInSection:(NSInteger)section return 12; 它返回 12 行检查您在 NSLog 中打印的数组大小并检查其大小
